Further, studies have found melamine to have adverse effects on the male reproduction system at doses between 5 and 25 mg/kg bodyweight including testes, sperm morphology and increased apototic index of spermatogenic cells at the higher dose [10]. When added to food products it indicates a higher apparent protein content but can cause kidney stones and kidney failure. In 2004, the global capacity amounted to about 1 million ton annually, with approximately 10% being used in food contact materials. Melamine is the same chemical that … The Dept of Health ordered the removal from the market of any Chinese foodstuffs containing milk and related ingredients including infant formulas, sweets, toffees, chocolates, biscuits, etc., and set about monitoring all baby formulas in South Africa. Melamine was also associated with massive pet food recall in the USA in 2007. Non-intentionally added substances (NIAS), Per- and polyfluoroalkyl substances (PFASs), Bradley, E.L. et al. Contaminants of Milk and Dairy Products: Contamination Resulting from Farm and Dairy Practices. Toxicological and health aspects of melamine and cyanuric acid. In cases where the amount of protein in a product is important, higher protein levels will fetch higher prices. Melamine is used in the production of melamine resins, typically by reaction with formaldehyde. Other sources of melamine in foods: The report subsequently published by the WHO set the lower benchmark dose (BMDL10) at 35 mg/kg body weight/day based on the development of urinary bladder stones [15]. It is used industrially to make hard wearing, heat resistant counter tops such as are used in kitchens and canteens. Melamine has a half live of approximately 6 hours in humans and undergoes renal clearance. In the European Union where melamine is authorized as a monomer and an additive in plastic food contact materials, the TDI was subsequently also lowered to 0.2 mg/kg body weight and the specific migration limit set at 2.5 mg/kg food (Commission Regulation 1282/2011). The Food Packaging Forum provides independent and balanced information on issues related to food packaging and health. Switzerland. In doing so the Food Packaging Forum addresses all its stakeholders, including business decision makers, regulators, media and communication experts, scientists and consumers. A TDI of 0.2 mg/kg body weight was derived from that estimate. The infant formula had been illegally stretched with melamine, because the substance mimics higher protein content. Unfortunately, when the milk is spray dried the melamine content is concentrated and when used as the basis of an infant formula, often a baby’s only source of food, the concentrated and continuous exposure can lead to kidney failure, kidney stones and death as experienced on a very large scale in China. Melamine food pans are great for cold applications like deli displays, buffets, salad bars, and more. Receive a bi-monthly summary of the latest news and stay up to date with developments in the field. 2012. Melamine is used to make resins and table ware amongst other applications. Melamine dishes were popular when introduced during the 1950s and 60s, but when Corelle arrived on the scene in the early 1970s, Melamine faded into the background. R.1054. Melamine has emerged as one of the major food adulterants world over. (2012). In the year 2008 there were several reports that high levels of melamine have been detected in food and feed from around the world which triggered large-scale melamine testing of food products. In what Products has Melamine been Found? Presence of melamine in pesticides and fertilizers As melamine is high in nitrogen it is reported to be a component in some fertilizers. Consequently, low levels of melamine can migrate into milk and dairy products from food contact material. “Melamine induces human renal proximal tubular cell injury via transforming growth factor and oxidative stress.” T, Puschner, B. et al. “A worldwide food safety concern in 2008 – melamine-contaminated infant formula in China caused urinary tract stone in 290,000 children in China.”. Melamine made from carbamide and one of the side products that is formed during production is cyanuric acid. Melamine is a mildly toxic, odourless, white crystalline powder that melts at 347 Degrees Centigrade. It is also used as an ecto-parasiticide in veterinary medicine. 2009. It has also been employed as a non-protein nitrogen, appearing in soy meal, corn gluten meal and cottonseed meal used in cattle feed. The US Food and Drug Administration (FDA) opened offices in three Chinese cities in order to assess and keep abreast of the situation. Because melamine is such a great insulator, it's also ideal for cold food and buffet displays. CH-8045 Zurich (2010). Melamine is illegally added to food and food ingredients in order to give the impression that the protein content of the food is higher than it really is. et al. Melamine may migrate from coatings, table ware and household appliances into food. As a result of this dilution the milk has a … Many of these foods proudly display their American-made status on their websites. In many countries, food manufacturers who deal with milk and milk products now use the newer screening technologies to ensure that the melamine is within the regulated limits. Articles are written by trained technical food and nutrition professionals who source information from respectable scientific sources throughout the world. In 2008, melamine was found in the products of … The Dairy Standards Agency and the SA Milk Producer’s Organisation alerted members and producers to the scare and specifications of all incoming materials was rigorously checked. “Melamine-induced renal toxicity is mediated by the gut microbiota.”, Yang, Y. et al. • Cyromyzine is a systemic insecticide, which get absorbed in to plant tissues. However, melamine contamination is still possible in American-made foods. The study looked at 12 individuals. Melamine may induce neurotoxicity [11, 12], altered TCA cycle, and gut microflora structure [13]. Food manufacturers were adding melamine to artificially increase the protein content in the milk. “Evaluation of metabolomic profiling against renaltoxicity in Sprague-Dawley rats treated with melamine and cyanuric acid.”, Reimschuessel, R. et al. The TDI is not applicable in case of significant concomitant exposure to cyanuric acid or another substance increasing the risk of urinary crystal formation. (2010). Migration levels up to 332 µg/kg food were observed by Bradley and colleagues [1]. Other applications are furniture, the construction industry, banknotes, printed textiles, concrete additives and flame retardants. In 2008, the U.S. FDA lowered the TDI from 0.63 to 0.063 mg/kg body weight. The addition of melamine to foodstuffs and feed is not approved by the World Health Organisation nor by any national authority anywhere in the world. For example, in the case of wheat gluten used for animal feed, the product may be diluted with cheaper low protein materials and then “boosted” with melamine. Opinion of the Scientific Panel on food additives, flavourings, processing aids and materials in contact with food on a request from the Commission related to 2,2-bis(4-hydroxyphenyl)propane (Bisphenol A). Over thirty dairy companies were found to be involved in the scam which was reported to have affected production between March and August 2008. Melamine is listed on the Swiss inventory list of substances authorized for the use in printing inks. In the U.S., melamine is authorized as adhesive and component of coatings in food packaging. Melamine, the chemical that has tainted milk formula in China and made thousands of children ill, may have been part of the food chain in China for a long time, say food experts. 1-13. doi:http://dx.doi.org/10.1016/B978-0-08-100596-5.00698-3, The FACS objective is to provide consumers with scientifically correct information on food and nutrition issues. In mammals, melamine can also be converted to cyanuric acid by the gut bacterium Klebsiella terrigena (FPF reported) [9]. “Assessment of melamine and cyanuric acid toxicity in cats.” J, Kim, T.H. Melamine is primarily found in products made in China. It gives the dishes a harder, more durable feel than standard plastic. It was said that “melamine migration was detected from all samples” that were tested. The melamine-contaminated milk incident in China was one of the most serious events considering that young children are relatively vulnerable to food contaminants. While not legally binding, the levels allow countries to ban importation of products with excessive levels of melamine. Migration levels up to 332 µg/kg food were observed by Bradley and colleagues. The migration process is influenced by the temperature of the heat treatment and to some extend by the time of the heating and the acidity of the food [1, 2]. Why was melamine added into milk and powdered infant formula In China, where adulteration has occurred, water has been added to raw milk to increase its volume. Because of its high nitrogen content, this chemical has been illegally added to foods such as milk powder to increase the total nitrogen concentration, which is used as an indicator to estimate the protein content. A January 2013 study published in JAMA Internal Medicine found that melamine can leach from dishes into food, and consequently your body, if you use melamine tableware with hot foods. Melamine is used as a monomer in the production of melamine resin. Food contamination continues to occur in modern times. We determined the concentrations of melamine, ammeline, ammelide, and cyanuric acid in meat, fish and seafood, cereal products, beverages, cooking oil, and vegetables (n = 121) collected from Albany, New York, United States.In addition, food packaging (n = 24) and animal feed (n = 12) were analyzed to determine the sources of melamine and its derivatives in foods. For this topic Food Packaging Forum has prepared an in-depth dossier, Staffelstrasse 10 Transfer of melamine from melamine-containing feed to cow’s milk has been reported. The infant formula scandal in 2008 let the WHO to convene an expert meeting in 2009 [14]. To help avoid melamine in pet food, you can purchase foods that are manufactured in the United States. R. 1054. By March 2009, about one year after the adulteration of milk had begun in China, the melamine issue in South Africa had been fully contained. “Effect of melamine on potassium currents in rat hippocampal CA1 neurons.”, Xie, G. et al. 1. The migration process is influenced by the temperature of the heat treatment and to some extend by the time of the heating and the acidity of the food [1, 2]. Melamine is a chemical compound that has a number of industrial uses, including the production of laminates, glues, dinnerware, adhesives, molding compounds, coatings and flame retardants. See, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). What are the Symptoms of Melamine Poisoning? Melamine is a name used both for the chemical and for the plastic made … Reference Module in Food Sciences. The United Nations' food standards body, Codex Alimentarius Commission, has set the maximum amount of melamine allowed in powdered infant formula to 1 mg/kg and the amount of the chemical allowed in other foods and animal feed to 2.5 mg/kg. Detection was probably thought to be unlikely because melamine is not expected to be in food and has never been routinely tested for. “Acute low-dose melamine affects hippocampal synaptic plasticity and behavior in rats.”, Yang, J.J. et al. Several children died of kidney failure and the number that ultimately received attention may have reached 100,000. Melamine is widely used in plastics, adhesives, countertops, dishware, whiteboards. The high levels of melamine in infant milk resulted in China in very severe health effects in infants and young children. Some approved uses of melamine in the United States are as an indirect food additive as a component of glues and adhesives, and in Europe as a monomer and as an additive in plastics. The TDI is basically the amount that an adult can consume on a daily basis over a lifetime without an appreciable risk to health. The Food Packaging Forum Foundation is a science communication organisation. Melamine is rich in nitrogen, a property that is similar to protein. The Service is administered by SAAFoST – a non-profit organisation for food scientists and other technical food professionals. In the case of milk adulteration, water may be added and then “boosted” with melamine to yield normal “protein” levels. Melamine In the second week of September 2008, the Commission was made aware that high levels of melamine were found in infant milk and other milk products in China. “Metabonomic evaluation of melamine-induced acute renal toxicity in rats.”, Chen JS. By February 2009 the number of reported contamination events had reached a very low level. It may be toxic to the kidney, and has been associated with an increased risk of kidney cancer. These levels are typically below 1 mg/ kg1. Melamine is a triazine compound with the molecular formula of C 3 H 6 N 6 and is composed of 66.6% Melamine is a synthetic chemical used in a variety of industrial applications including the production of resins and foams, cleaning products, fertilizers and pesticides. Elsevier, pp. Low levels of melamine appeared in local milk for a short time as a result of contaminated animal feed that had been fed to cows. Melamine is a minor metabolite of the pesticide cyromazine and is used in some fertilizers. Melamine is a chemical used in the manufacturing of plastic dishes, cups, and other tableware. R1054. Melamine may migrate from coatings, table ware and household appliances into food. A number of companies also instituted monitoring mechanisms to mitigate the risk for contamination, by frequently checking the raw /source ingredients that are traditionally used in milk and other products. Some approved uses of melamine in the United States are as an indirect food additive as a component of glues and adhesives, and in Europe as a monomer and as an additive in plastics. Fortunately, the adulteration problem remained confined to China and Chinese products which facilitated safety checks, market withdrawals and international recalls. Read More on This Topic It has many industrial uses, including in the production of laminates, glues and adhesives, moulding compounds, coatings, and flame retardants. More than 53,000 infants have been diagnosed with severe traumas such as urinary tract complications and acute kidney failure. Irritability, high blood pressure, blood in urine, little urine, signs of kidney infection. Analysis of melamine in … Disposition of hogs and chickens from farms identified as having received pet food scraps contaminated with melamine and melamine-related compounds and offered for slaughter. Melamine (1,3,5-triazine-2,4,6-triamine) is a nitrogen-rich molecule (C 3 H 6 N 6), with 40% nitrogen by number of atoms. Although no Chinese milk or milk powders had been legally imported into South Africa since about 2003, melamine had found its way onto local shelves via imported goods from that country that contained contaminated milk as an ingredient. In 2008, 300 000 children became ill and six of them died after consuming contaminated infant formula. Study: Analysis of melamine migration from melamine food contact articles. Swiss inventory list of substances authorized for the use in printing inks. Regulation 1054. Melamine is not classifiable as to its carcinogenicity to humans due to a lack of toxicological data, and has been found not to be genotoxic in vitro or in vivo [3, 4]. Considering that the presence of cyanuric acid increases the risk of kidney stone formation, this recent finding induces further caution. Melamine through food chain • Cyromyzine is a widely used pesticide in most of the countries. Thanks to its heat-resistant properties, melamine is also great for kitchen tools that are used when handling hot soups and boiling water. Melamine itself is not used as a pesticide although it is recognized as one of the breakdown products of the pesticide cyromazin It is also used in the manufacture of plastic dishware, bottle caps, whiteboards, coatings, adhesives and insulators. “Comparison of the migration of melamine from melamine-formaldehyde plastics (‘melaware’) into various food simulants and foods themselves.”, Hsieh, T.J. et al. Secondly, it may be blended with other additives for the manufacture of dinnerware, chopsticks and electrical equipment. Ultimately, many hundreds of different products were affected. Melamine (also known as tripolycyanamide, or 2,4,6-triamino-1,3,5-triazine) is an industrial chemical used for the production of melamine resins which can be used in glues, paper, textiles, kitchen utensils, etc. (2007). No cases of sickness or death due to the ingestion of melamine are known to have occurred in South Africa However, sampling and testing by the Dept of Health and a network of co-operating organizations continues to the present. Melamine is the same chemical that was implicated in the pet food recall in 2007. The researchers used silverware (forks, spoons, knives) and tableware (plates, bowls, tumblers, cups) that were purchased at retail. The Food Packaging Forum summarizes applications, risks and regulations of the substance. Albeit a small sample size, six ate hot soup for breakfast out of melamine bowls and the other six ate it out of ceramic bowls It is not naturally occurring and is not allowed to be added to food. R 1054. “Renal crystal formation after combined or sequential oral administration of melamine and cyanuric acid.”, Zheng, X. et al. Its high nitrogen content makes it a cheaper protein alternative, resulting in illegal adulteration of food and feed. Relatively small quantities of melamine yield relatively high “protein” values which can make this fraudulent activity quite profitable as long as the perpetrators can escape detection. 1.Melamine Rapid Determination of Melamine in Food Melamine is used as the main raw material of melamine resin, a thermosetting plastic, but recently it is receiving considerable attention due to numerous incidents of food contamination with this substance. Melamine is not permitted in food or feed stuffs. Some 5,000 inspectors were deployed in the dairy industry to monitor the situation, take samples and conduct tests. Regulations Relating To The Maximum Levels Of Melamine In Foodstuffs An even bigger and much more serious scare erupted in September 2008 when melamine was found to be responsible for the hospitalization and / or treatment of tens of thousands of Chinese children suffering from kidney stones and related problems. Once again, melamine had been illegally and fraudulently added to a food product, on this occasion milk for human consumption through which it found its way into infant formulas and a wide range of products that have milk or milk powder as an ingredient. to keep Food Packaging Forum’s work going. The European Food Safety Authority (EFSA) was asked by the European Commission to provide a scientific opinion related to the presence of melamine and the structural analogues (cyanuric acid, ammeline and ammelide) in food and feed. In January 2009 the Department of Health set maximum melamine levels for all foodstuffs at 2,5 mg/kg and, for infant formulas intended for children under 36 months of age, at 1mg / kg. Melamine Pet Food Recall of 2007 On March 15, 2007, FDA learned that certain pet foods were sickening and killing cats and dogs. Updated. More recently melamine has been found to be contaminating human foods, in particular milk powder, milk and yoghurt and was reported to have been used in 22 brands of infant formula. The concern over melamine adulteration spread to include a number of different types of dry protein materials in both animal and human-food sources. Foodstuffs containing higher levels were deemed to be contaminated, impure or adulterated. (2011). Information from FACS articles, identified as such in the article index, can be freely used on condition that the source is acknowledged. No more tainted milk powder anymore . Melamine is known to cause kidney failure and kidney stones in humans and animals when it reacts with cyanuric acid inside the body. Melamine, also called cyanuramide or triaminotriazine, a colourless crystalline substance belonging to the family of heterocyclic organic compounds, which are used principally as a starting material for the manufacture of synthetic resins. Consequently, low levels of melamine can migrate into milk and dairy products from food contact material. (2013). High visibility and the potential public-health threat prompted the U.S. Food and Drug Administration (FDA) to rapidly issue a standard test method for the analysis of melamine in protein materials. “Migration of melamine from can coatings cross-linked with melamine-based resins into food simulants and foods.”, Bradley, E.L. et al. This site uses cookies, including third-party cookies. Melamine resin can be used as surface coating for paper, board and beverage cans and jar lids as well as in the production of body panels and household appliances. Standards for melamine in food. If you continue to use this site you agree to the use of cookies. Melamine had been illegally and fraudulently added to imported Chinese protein that was being used in the manufacture of pet food – it resulted in possibly the biggest ever pet food recall. Melamine is of increased toxicity when fed in combination with cyanuric acid leading to the development of severe renal dysfuntion [6, 7, 8]. (2012). One infant formula tested in China was found to contain 2, 500mg / kg of melamine! By the end of September, 27 individuals had been arrested in connection with the scandal and it was found that about 12% of the milk powder products sampled contained melamine. Treatment may include fluid infusion, urine alkalinisation, electrolyte and acid-base correction, removal of kidney stones, etc. Melamine can pass the placenta and can be transferred via breast milk. To check adulteration, food safety regulator FSSAI has proposed for the first time fixing a maximum permissible limit of melamine content in milk and related products. These levels are typically below 1 mg/ kg1. Fischer, W.J., Schilter, B., Tritscher, A.M., Stadler, R.H., 2015. The issue of melamine presence in Chinese dairy products is considered a new and separate issue from the pet food … In vitro melamine has been shown to lead to renal tubular cell injury via apoptosis, inflammation and fibrosis at concentrations up to 1000 µg/mL [5]. The World Health Organisation (WHO) set tolerable daily intake (TDI) levels for melamine ( 0,2 mg/kg body weight) but no “safe” level was ever set due to uncertainty about the specific effects that it may have on the human body, especially infants. (2010). (2010). Melamine is a nitrogen-based compound used in commercial and industrial plastics, such as eating utensils and laminates, whiteboard wall paneling, flooring and Formica countertops. Milk, milk powder, baby food and formula, yoghurt, biscuits, sweets, chocolates, toffees, tea and coffee products, instant coffee, chicken, eggs, pet food, animal feed, fish food, raising agents, etc. A melamine scandal broke out in March 2007 when the substance was found to have caused the death of many pets in various parts of the world, including South Africa. On investigation the adulteration of the food and feed melamine was traced back to China. Because normal routine laboratory tests for protein do not distinguish between protein and melamine, the final results are not questioned if they happen to fall within expected values.
