Contaminants in the food chain

Contaminant levels in food and feed are usually too low to harm consumers and animals but they can cause effects such as food poisoning and their presence or accumulation over time might affect animal and human health.

Environmental contaminants

Industrial and consumer chemicals present in air, soil and water.

Process contaminants

Formed during processing like high-temperature cooking.

How are consumers and animals protected?

Data collection

Member States tell us if foods are contaminated and by how much.

Risk Assessment

Scientists estimate the exposure of humans and animals to contaminants and the potential risks.

Risk management

Data and advice provide a scientific basis for decision-making by risk managers.
