Managing Chemical Contaminants: Issues & Challenges Faced by the Food Industry

Protecting consumers from chemical contaminants in food is vitally important if food industries are to retain consumers’ trust and confidence.  This requires a thorough understanding of potential contaminant hazards from raw ingredients, as well as an understanding of potential toxins that might form during food processing.  Modern analytical techniques have improved our awareness of such chemical contaminants, which allows for them to be better controlled.  However, some of the control measures that are now possible, through those advances in analytical methodology, have brought with them unintended consequences.  Risks do not always exist in isolation, and so regulatory authorities must often balance one risk against another — as, for example, occurs between chemical hazards and microbiological hazards.  Other compounds, long thought of as being only pesticide contaminants or veterinary drug contaminants, have recently been discovered to occur naturally in foods at trace levels; making their complete prohibition unfeasible.  The food industry has an important role to play in being transparent with these new discoveries, so that food regulators are better equipped to control unwanted contaminants, whilst not inadvertently placing undue restrictions onto their citizens’ food supplies.
