The food standards agency of the United Nations, Codex Alimentarius Commission (Codex) has framed new norms for melamine contamination in food items. Though the norms are applicable to exported Indian foods, it may not have much impact, as melamine is not common in India.
Melamine contamination had created great furore recently in China when baby milk powder was found to have high levels of melamine in it. It resulted in over 10,000 children falling sick and four dead. Earlier, pet foods made in China were recalled from the US market following detection of dangerous levels of melamine.
Presence of melamine in food is unavoidable, as it comes by contact from the containers used to store food items. However, traces of melamine present in foods do not pose health hazards. Only when the levels of melamine reach high concentrations, it is toxic. Codex has specified the maximum melamine levels permissible in food items. For baby foods, it is 1 mg/kg, while for all other food items, it is 2.5 mg/kg.
Melamine is a hard synthetic substance used mainly in making kitchenware, tableware, can coating and countertops. Even when melamine-coated containers are used in the manufacturing of food items, the melamine content in the food won’t reach toxic levels. This happens when melamine is added deliberately to foods to make them appear thicker. When melamine is added to watery milk, it will look richer and full of protein. Unfortunately, usual tests cannot detect the presence of melamine and would tag it as protein.
When consumed in large concentrations, melamine can cause renal problems. Hence it is banned all over the world.
Martijn Weijtens, chair of the Codex Committee on contaminants in foods said, “Establishment of maximum levels will help governments differentiate between low levels of unavoidable melamine occurrence that do not cause health problems, and deliberate adulteration – thereby protecting public health without unnecessary impediments to international trade.”
Codex has also specified maximum levels of aflatoxins, carcinogenic fungal toxins in foods and has given a code of practice to prevent contamination.
