The system of measure aimed at the prevention of disease and public health improvement reserves one of the central places to measure ensuring food safety. Modern human food, due to its multicomponent chemical pattern, besides energy sources plastics, vitamins, mineral substances and microelements, can involve a whole range of compounds, representing a potential threat to human health. Such compounds primarily include environmentally originated food contaminants: heavy metals, pesticides, nitrates, nitrites, n-nitro-scamines, bacteria and bacterial toxin, microscopic (mould) fungi and mycotoxins.
