What poses a risk?
Contaminants are substances that have not been intentionally added to food or feed and may pose a risk to animal and human health. These substances can be microbiological or chemical and can enter the food supply at various stages of its production, packaging, transport, storage or preparation. Food manufacturers operate quality assurance systems to avoid contamination during food production.
Safe food handling at home and in establishments where food is served is also critical to reducing the risk of contamination.
