Abstract

Food adulteration and contamination are as old as the civilization itself. It is the consequence of the development of civilization, over utilization of nature, industrialization and in a price for the progression. It is highly prominent in Urban areas of Bangladesh. It is the consequence of commercialism of business people who are doing this knowingly to maximize profit. Higher degree of awareness shown by the people with higher educational background. Government regulatory agencies are less confident regarding food standard testing, as reported in the study. Educated people show higher degree of awareness of how the quality of food should be maintained. Regulatory authority is found to be in confidant in testing the food standard which also reflects their negligence. Safe food means, in general, there will be no danger from harmful elements that are deliberately added to food products in the country. The economic development of this country rarely reveals the basic literacy and consciousness of mass people. Necessary steps are to be taken to protect the environment for our own existence.

 

Purpose of the study: Brief review of chemical induced food contamination, their consequences and control. Healthcare providers/Policy makers have a major role play to concerned field.

 

Materials and Methods: Comprehensive literature search followed by consulting healthcare professionals about adulteration and food contamination. Hospital, clinic, newspaper journalists, NGO workers were interviewed and asked help for necessary books, journal, newsletters. A few western magazine and newspapers also observed to get necessary concern. Projections were based on various types of adulteration in food served/sold to general people from variety of sources.

1. Introduction
Contamination is the presence of an unwanted substance where it should not be or at concentrations above recommended. Pollution is contamination that causes adverse biological effects to resident communities. Food contaminants and adulterants gave a new dimension in city life, together rest of the country. Rural people are less exposed to adulteration than urban people because of busy life, arrangement of food/spice item are mostly obtained from nearby grocery stores, chain shops and nearby open markets. Recent media reports on the misdeed in the food sector has revealed alarming scenario leading to massive public outcry. Although there is no official statistics regarding food borne illness, it is realized to be a major problem in urban areas of Bangladesh. Contaminated food, filthy and grimy environment of urban cities result in health hazard which may even cause deaths. The healthcare providers/policy makers’ role in environmental health is related primarily to being alert to the conditions prevailing in the community and of working with others to adequately control any of the attendant hazards.

 

2. Gross Outcomes of Chemical Contamination
Food remains a significant vehicle of disease organisms. Foodborne disease, more commonly but often incorrectly called “food poisoning,” is grossly underreported. In most instances the illness produced by contaminated food is mild and of short duration, but more severe outbreaks (such as hepatitis A, most commonly seen in public restaurants) can occur. Epidemics of food-borne disease are dramatic and sudden, and most people become sick within 6 to 24 hours after consuming the contaminated foodstuffs. The epidemic pattern of food-borne disease presents differently from the gastrointestinal symptoms (e.g. nausea, vomiting, and diarrhea) induced by intestinal enteroviruses. The safety laws and regulations of Bangladesh are as given in Table 1. WHO published-chemical exposure to toxic level is suspected to be involved in causing-

  • Carcinoma
  • Cardiovascular disease
  • Kidney, liver dysfunction Hormonal Imbalance
  • Premature birth
  • Suppression of Immune system
  • Impaired development of nervous system
  • Mental health problems and
  • Learning disabilities/Cognitive dysfunction

3. Results and Discussions
Food adulteration is the most notorious enemy of mankind. Civilization has its own drawback that even causing destruction of itself. Very few people raised voice on this but crippled by the facts of commercialism. The scope of this article is confined to chemical food contaminants and adulterants. A few discussions based on real life experience and recent studies or reports from various journals and news articles are summarized here.

 

3.1 Food and supply water contamination
Food and Supply Water Contamination Dhaka city, among huge amount of solid wastes every day from industrial discharge, fossil fuels, fertilizers, sewage sludge, municipality wastes and they are the major sources of heavy metals exposed to crops, vegetables and other food items from soils, causing serious health hazards to human beings [1-3]. A significant deportation of heavy metals like arsenic, cadmium, chromium, copper, lead, mercury, nickel, zinc, molybdenum and vanadium took place from soils to locally grown vegetables (spinach, tomato and cauliflower) grown in industrially polluted soils of Konabari at Gazipur and Keraniganj in Dhaka [4]. Due to absence of effluent treatment plants (ETP), the factory wastes are unloaded to farmlands, and conclusively contaminate the farm produce. In our country we have allowed things like food contamination and pollution to run riot. Till now, neither health ministry or the ministry of science and technology nor the ministry of industries, has conducted any examination of the pesticide- residue levels or toxic chemicals in the foodstuff being marketed [5]. Apart from these, the slum areas are both populated and are in greatest risk of notorious pathogen found both in food sample and supplied water (Table 2).

According to Dhaka Water Supply and Sewerage Authority (DWASA), it can currently supply 75% of water demand, out of which 85% is from groundwater sources (Deep Tube wells). The presence of toxic metals in Elephant road, Dhaka University, Jatrabari, and Demra area and toxic Pentachloro-Phenol (PCP) and existing pathogenic bacterial load in the WASA supplied drinking water sample from different areas of Dhaka city were found to be unacceptable for human consumption (Table 3).

3.2 Arsenic issue of drinking water
Twenty million people in Bangladesh are still drinking water contaminated with arsenic, a potentially deadly toxin discovered in supply two decades ago [8]. The Bangladesh government is failed to take initiatives to naturally occurring arsenic in drinking water across large areas of rural Bangladesh, as reported by Human Rights Watch. Approximately 20 years after initially coming to international attention, an estimated 20 million people in Bangladesh-mostly rural poor-still drink contaminated water over the national standard [9]. Bangladesh’s health system largely neglects the consequence of arsenic exposure on public health. An estimated 43, 000 people die every year from arsenic-related contagion in Bangladesh, according to another study [10]. The government identifies people with arsenic-related contagion primarily via skin abrasion, although the vast majority of those with arsenic-related illnesses don’t develop them. Those exposed are causative agent of cancer, CVD, and lung disease as a result, but many receive no health care at all [11].

 

3.3 Food adulterants
Important food hazards include microbial contamination, pesticide remainder, misused additives, chemical impurities, including biological toxins and adulteration. Although microbiological contamination and chemical hazards are taken into account, it is realized that food adulteration and fraud should not be overlooked considering their consequence in public health [12]. Food adulteration includes various forms of practices, such as mixing, altering, camouflaging the quality of food by mis-labelling, putting up decomposed or expired food, and adding toxic substances [13]. About the proportion of adulterated food items in the market varied between 70% to 90%. Around 80% food items in the market were found adulterated in an incidental survey by public health laboratory of Dhaka City Corporation in 2004 [14, 15]. International Centre for Diarrheal Disease and Research, Bangladesh (ICDDR, B), estimated 150 food items in the country. More than 50% of the food samples they tested were adulterated reported by the Institute of Public Health (IPH). Textile dyes, which are highly noxious to health, are being openly used as food coloring agent [16]. Clay powder is mixed with the mixture of turmeric powder and cold toxic yellow dye to make it yellow. Water and salt are well mixed with these species to increase the weight. Mangoes, watermelon, litchi, watermelon, pineapple, papaya and bananas are artificially ripened using a carcinogenic chemical called ethylene oxide (Table 4). In bananas, calcium carbide is used that becomes a spray Acetile-gas to generate heat.

Dalda (hydrogenated vegetable oil/ fat popular in South Asia) used in cooking is an example of a worst case false. "Our stomach temperature is 37 degrees Celsius and the melting point is 54 degrees Celsius Dalda. So, there is no reason that Dalda can be engrossed by the body [18]. Most sweetened condensed deserts sold in the market actually comprises palm oil which is used as an alternative for cow’s milk and therefore most sweetened condensed milks out there do not contain milk at all [19]. Fish is considered to be an essential protein for people of all ages. Many fish sellers spray formalin in fish in an assorted manner, it makes the fish or fruits stiff and keeps them looking fresh for longer (Table 5). Undoubtedly human health is now under the domination of formalin, in our country about 400 tons formalin is being imported which are goes to human stomach, creates deadly mistreats on long term exposure (Table 6), even though for laboratory or research purposes 100 tons of Formalin is more than enough, 80% of the imported formalin is directly related to business purposes. Three-fourths of the marketed vegetables, fruits, and fish contain pesticides and formalin residues. The consumption of such foods might lead to serious diseases [20].

 

Reasons

Details

A cheap method to prevent Post harvest Loss

To prevent this post-harvest loss one of the cheap methods is to use formalin and other toxic chemical which helps to keep this fish fresh for a long time.

Lack of technical knowledge

Lack of proper technical knowledge contributes in use of waste material in fish culture, improper handling after post-harvest and use of formalin and other toxic elements.

Lack of ice box, unavailability of ice, high price of ice, lack of cold store to keep unsold fish.

Ice/Icebox is expensive. Main problem in the market of Bangladesh is there is lack of cold storage in the market place. As a result, there is no proper way to preserve unsold fish.

Lack of awareness

Most of the traders do not aware of the danger of using these harmful chemicals. On the other hand, customers are also not properly aware of this issue.

Lack of government initiative

Co-ordination between authorities is a major issue, does not appear to be any cohesive view regarding procedures and penalties for the same offence by officials from same organization.

Lack of policy framework

Food laws and regulations are mostly outdated and fragmented. Even the new Safe Food Act 2013 is not free from this as it is basically modeled on the Pure Food Ordinance of 1959.

Inadequate Penalties

Considering the extent of harmfulness of food adulteration, penalties mentioned in law is insufficient. For an example, the penalty for food adulteration is maximum term of six months of imprisonment or up to a maximum fine of BDT 1000 which is equivalent to EUR 10.77. Considering the gravity of the offences this punishment is not hard enough.

Table 5: Underlying Reasons Behind Adulteration Issue in Fish Supply Chain of Bangladesh [21].

 

Ironically even food color is being adulterated. Cheap food color is finding its way into many types of food. This includes the jilapi, beguni, alu’r chop, piaju. Ice cream, chewing gum, candy, chips, and even biryani may contain huge amounts of low-quality food color. Cooking oil that is so widespread too deep fry items should only be used once but many food vendors and eateries recycle burnt oil. Once the oil is used for cooking, it becomes oxidized. The more the oil is used, more pre-oxide will be created which is really disastrous for the body. It’s getting more toxic with continued usage. In 2017, police seized around 3000 eggs suspected to be artificial during a raid in Patiya upazila, Chittagong. They also arrested two men-an egg wholesaler and another is supplier-suspected to be involved in the trade and marketing of fake eggs [22]. Doubt also pointed in rice also. The term ‘plastic rice’ was focused by the online media around 2010, when China outlined its use for adulteration of a premium rice called Wuchang, which is known for its aroma [23].

 

Exposure routes

Effect on human

Carcinogenicity

Formalin has the potential effect to cause cancer, repeated and prolonged exposure increases the risk of cancers of the lung, nasopharynx, oropharynx and nasal passage

Reproductive health

It has a harmful effect on reproduction system by inducing oxidative stress.

Skin (dermal)

Prolonged and repeated contact with formalin could cause numbness (lack of feeling) and a hardening or tanning of the skin

Eye contact

Formalin solution splashed in the eye can cause injuries from transient discomfort to severe such as loss of vision

Table 6: Effect of Formalin Treated Food Consumption on Health [21].

 

The Institute of Public Health (IPH) in Dhaka and the World Health Organization (WHO) in their joint study on food adulteration in 1994 tested 52 street vendors and found that all of their food samples were contaminated with different types of pathogenic microorganisms. They also conducted another study in 2003 in Dhaka city and found that around 100% of sweetmeats, 25% of biscuits, more than 50% of breads and 60% of ice creams (Table 7) were extensively adulterated [24].

Table 7: Adulterants Used in Different Food Items of Animal Origin as Reported in Lay Press Reports [17].

 

Consumption of adulterated food items may cause asthma, sore throat, larynx constriction, bronchitis, skin infections, allergic reactions, diarrhea, hematuria, circulatory failure, numbness, dizziness, kidney failure, stomach cancer, liver cancer, nervous disorders and many other diseases (Table 8). After consumption of adulterated food items, thousands of people are becoming sick. Children are the worst victims. An estimated three million people suffered from diarrhea during 2005-2009 and about 15% of children died in 2011 as reported by the Directorate General of Health Services [25]. The long-term effects are also very severe especially the incidence of renal failure, liver damage and cancer which are alarmingly increase in Bangladesh. The accumulation of heavy metals, such as lead, chromium and arsenic accumulate in the body may causes kidney and liver failure and develop anomaly among children. Non-selective and aberrant use of antibiotics in poultry without following withdrawal period may result in unexpected residues in animal food and could cause serious health hazards to consumers. Research reports on antibiotic slags in broiler meat and liver from different farms and local markets for the presence of slags of ciprofloxacin, enrofloxacin, oxytetracycline, doxycycline and amoxicilin antibiotics revealed significant level of exposure of antibiotic residues. There’s a greater chance of declining immunological responses and can detrimentally affect intestinal microbiota in susceptible individual. According to Prof. Muniruddin Ahmed (Clinical Pharmacy and Pharmacology, Dhaka University) Cooking cannot destroy antibiotic residues, which made them resistant to antibiotic treatment [26]. Most Edible Oil are adulterated and most of the soybean oils, mustard oil and ghee sold to consumers are substandard.

Milk in rural areas is usually devalued with dirty water, which may cause hepatitis. People have now come to know about a newer milk adulteration technique where sorbitol, and detergent used as thickening. ICDDR, B recent studies shows nearly 75% samples from primary-level producers were contaminated with coliform and more than 50% with fecal coliform bacteria. At the collection points, samples were found contaminated with a high number of coliform bacteria and fecal contamination of more than 90% while more or less 40% of the samples had a high E coli count [33]. Vegetable and fruit samples collected from surrounding Dhaka (Savar, Dhamrai and Tongi) show the presence of textile dyes may cause diarrhea, food poisoning and other GI problems in the short-term, but in the long-term toxic materials will accumulate in the body with serious health implications [38].

 

3.4 Energy drinks vs carbonated drinks
The government has decided to prohibit the production, marketing and import of energy drinks under the guise of carbonated beverages with immediate effect [39]. The Bangladesh Standard and Testing Institution (BSTI) at a council meeting on also resolved to take legal action against the companies that have been advertising their products as energy drinks after having them listed as carbonated beverages with BSTI. The move came after the Bangladesh Food Safety Authority (BFSA) wrote to BSTI about the production of energy drinks in the name of carbonated beverages should be discontinued, as the ingredients of the two are significantly different. There is no standard fixed for energy drinks in the country, Industries Minister told parliament once. Authority received complaints about the use of various highly addictive substances, including caffeine and opium, in energy drinks [40]. In 2012, a test conducted by Department of Narcotics Control on energy drinks from several local and foreign merchants had found unrestrained amount of beer, alcohol, artificial caffeine and sildenafil citrate (Generic of Viagra) as ingredients [41]. The production and marketing of energy drinks under a license for carbonated beverage is deception, illegal under several laws including the BSTI Act and the Food Safety Act. Initially, the government will forbid companies to discontinue their production and marketing of energy drinks. Punitive actions will follow if they do not comply, said the official. The government will also revise the import policy in order to boycott the foreign energy drinks with harmful ingredients [42].

 

3.5 Safety issues of bottled water
So-called mineral water supplied to household and offices in jars are not tested at all. Mostly, the water is filled in the jars right away from the tap and sometimes in the empty bottles of some of the well-known mineral bottle brands [43]. The Bangladesh Agricultural Research Council (BARC) has of late made a sensational revelation regarding the quality of water different companies supply for drinking in and around Dhaka. According to the findings of the government study, 'coliform bacteria' (pathogens from feces of humans and animals) has been found in 97% of so-called filtered water supplied in jars to households, shops and offices in the capital city of Bangladesh. A team of BARC researchers determined the 'horrifying' data while studying the level of minerals in jars and bottled water marketed in Dhaka city. The researchers sampled 250 jars from across the city's familiar places Gabtoli, Mirpur, Mohakhali, Mohammadpur, Dhanmondi, Airport, Uttara, Banani, Gulshan, Rampura, Malibagh, Bshabo, Motijheel, Jatrabari, Keraniganj, Sadarghat, Chaawk Bazar, New market, Elephant Road, Karwan Bazar, Farmgate and on the city's outskirts at Aminbazar, Savar and Ashulia. The level of 'coliform bacteria' in the samples collected from Gulshan, Banani, Bashabo, Chaw Bazar, Elephant Road areas areas was found significantly high in the research [20, 44]. Meanwhile, a mobile court busted six fake mineral water plants in Bosila area, near Dhaka’s Mohammadpur and convicted six staffers to different terms of jail. The team also seized 2000 jars of water and destroyed those later [45].

 

3.6 Food adulteration during Ramadan
The crime of those selling adulterated and unhygienic food items is very serious and strict action needs to be taken as per law against such guilty persons. According to media reports some 600 field-level sanitary inspectors are working across the country to ensure food safety for all during the holy month of Ramadan. Even more unfortunate is the fact that this nefarious practice increases exponentially during the month of Ramadan. It was found that coloring agents are used in oils, lentils, juices, sauses, spices. Formalin and carbide used in milk, meat, fish and fruit [46]. The shopkeepers and the merchants many of them with a pious fade try to earn a large amount of profit by this unethical practice, and so they play with the life and health of the people. They mix dangerous things in the daily eatables. These merchants and traders are the enemy not only of the nation and their own children but of the entire mankind. The holy Prophet (PBUH) has disowned those who indulge in this immoral business. He said the adulterator is not one of us [47].

 

3.7 Sub-standard vermicelli (shemai) and cow fattening ahead of Eid
Adulterated vermicelli flooded different markets in the capital ahead of Eid-ul-Fitr, one of the biggest religious festivals of the Muslims, posing a serious threat to public health. A section of corrupt businessmen is busy in manufacturing low-grade vermicelli in the port city ahead of Eid-ul-Fitr as the food item has a high demand in the day. According to local sources, some of the factories are using unprocessed palm oil and animal fat to produce Laccha vermicelli while harmful chemicals and toxic color were also used to make the food items. Bangla vermicelli is produced using flour and water and Laccha is produced with sugar, flour, water and oil. Mostly, the vermicelli is dried in unhealthy condition in the rooftop of the factories [48]. An anonymous, a seasonal vermicelli maker said a section of merchant in the city bought the inferior vermicelli and sell them tagging labels of famous companies. BSTI officials left a comment as Bangla vermicelli is used to make by seasonal factory for a certain time, it is not compulsory to take license from BSTI, but the factory should take certificate issued by the Sanitary Inspector [49-52]. With Eid-ul-Azha in front, the Poribesh Bachao Andolon (Poba) has recently urged the government to monitor how cattle is being reared and fattened in the farms in the country [53]. Consciously causing such harm to public health so as to raise the price of cows is a crime, and must be dealt with swiftly. The use of steroids, antibiotics, growth hormone and other chemicals is forbidden by the Animal Feed Act 2010. Perpetrators may be faced with a year in prison, a Tk 50, 000 fine, or both. A large number of farmers are engaged in cow fattening just before 3 or 4 months of Eid-Ul-Azha (Muslim festival), when they sell the animals with lucrative price. Visiting different villages in Ataikula, Santhia, Bera upazilas of Pabna, and Baghabari, Shahjadpur areas in Sirajganj, these journalists found that almost every domiciliary was using steroids, antibiotics and other chemicals for months in overt violation of law. Everyone from cattle farm owners to landless farmers wanted to take full advantage of this. These cattle-fattening drugs are also widely used in Manikganj, Faridpur, Barisal, Nilphamari, Chuadanga and some other districts. Meat consumption from these animals poses severe health risks for humans, stated by the proficient [54]. The changes to the cattle to be slaughtered caused by these injections are not merely cosmetic-severe health damage is done to humans by the consumption of this meat. While most traders would still claim that the fattening chemicals were not harmful, there is reason to believe these chemicals may cause cancer, kidney disease, and infertility in women [55].

 

3.8 Penalty imposed on famous eateries
Isn't it surprising that like many occasional drives against various crimes, the fight against unhealthy food, too, has assumed the character of an occasional activity? While this should have been a continuous and uninterrupted activity round the year across the country, scattered and infrequent moves here and there, leave no everlasting impingement on the sellers and producers of unauthentic food items of all varieties. Gazette reports say that the drive against food adulteration is a recent disport. The Bangladesh Food Safety Authority (BFSA), the state watchdog to regulate the sector is reportedly checking the capital's food markets under the supervision of an executive magistrate. One has reasons to question the logic behind the drive in the capital alone, that too with just one magistrate. The effectiveness of the drive is bound to cause nothing more than a ripple with mobile courts penalizing a few sweetmeat shops, restaurants and if at all, some kitchen market sellers. The fact that such drives, scattered and impassive, failed to bring any control in the country's food market cannot be disputed. However, famous eateries/food chains are not devoid of these cases of adulteration and substandard food staffs. Penalty imposed on these popular food chain/shops should impart an idea to general people that paying high price is not always an indicator of good quality. Even a few of them were condemn more than once or twice for the same reason but below standard food serves never ended (Table 9). For a better view references regards are attached in this table with date published.

Table 9: Eateries/Chain Shops Raid List for Adulteration/Substandard Food Serving.

 

Inadequate monitoring of food markets may have exposed people’s health to serious hazards from consumption of substandard and adulterated foods. In the absence of corrective measures, punishing the accused convicts-at times by way of colossal monetary penalties-is not permanent solution of dealing with the complication. A properly organized mechanism with efficient manpower and regular audit round the year can only bring things to some form of order. In this context, it is urgent that the BSFA and allied agencies such as the BSTI and the city corporations which also run such drives maintain a well-coordinated plan of action. It is also important that punitive actions should result in overall quality and standard improvement of food of all varieties. To monitor the situation, inspection and sudden raids are welcome, but it must not be overlooking that inspection is just one of the many ways to rein in food adulteration.

 

4. Recommendations
While contamination of food may be due to disregard, planned adulteration by noxious chmical agents for long shelf-life of products and increasing the volume in size and weight-among the many twisted methods-is so uncontrolled that it is almost impossible to find anyone who does not confront an undesired moment of food-related ailment at least once a year. Consideration of the incidence thus calls for a whole package of initiative actions. In advanced countries this involves a preventive and automated environment of manufacturing, supervision, storing and packaging foods to prevent infection and contamination in the entire chain. However, in situations predominating in this country, it is not merely about maintaining a clean chain but putting in strong preventions so that dirty pool in the business could be gridlocked. Sources of harmful stuffs must be blocked, if necessary, ban on imports or local production. Strong advocacy on the detrimental effects of consumption should be routinely done. At the same time, training on safe and scientific methods of preservation of food products should also be a high priority in an attempt to curb adulteration. Adulteration and contaminant control are a never ending, on the other hand a continuous process. It will increase with time as the civilization go ahead. Community pharmacists and allied health professionals should be familiar of the local occupations, companies, and factories and to be cognizant of the initial outcomes of disease. Again, they should become acquainted with the local community and to acclimate the principles of health and medical care to the particular situations encountered. The pharmacist’s continuing education requirements should include watching the local pattern of society and its diseases, and changing the emphasis toward evolving disease patterns and their control. Government and regulatory authorities are to play strong role in controlling food contaminants and adulteration.


5. Conclusion
With constant change to the physical, biological, cultural, social, and economic environment, both healthcare providers and citizens should cultivate an informed awareness of these changes, and health providers should adapt their methods of health education, disease prevention, and disease control to the changes in each community. This is especially true food daily consumed, which require concerted community action for their control, but providers may play a much more fundamental and personal role in controlling food-borne diseases; often, the first indication of an outbreak of food-borne disease is time-limited, with an unusually large number of people seeking relief from health hazards. The crucial role in environmental health is related principally to being alert to the circumstances predominating in the community and of working with others to sufficiently control any of the attendant hazards. Government authorities, NGOs and other private organizations (e.g. Pharmaceutical companies) should take initiatives further to ameliorate food and drinking water situation which is worst among all other previous times. General people should be aware of these facts of mischiefs and take necessary steps on their own. A year-round campaign regarding these issues in public places, electronic media and even in rural areas can bring a change as brought by diarrhea, Vitamin A campaigns back in 70’s and 80’s.
