Includes non-microbial contaminants such as pesticides, heavy metals, and other toxic substances. Learn about contamination sources such as the environment, cooking methods, and inappropriate agricultural practices.
Chemical and Physical Contaminants
Research Publications from Peer-Reviewed Journals: Chemical Contaminants
USDA. ARS. Food Safety Research Information Office.
Research publications on chemical contaminants from peer-reviewed journals. Some publications may be early view or ahead of print. Citations and abstracts are available to all users while full-text availability depends on institutional access levels.
Chapter 23: Environmental Chemical Contaminants and Pesticides
Seafood Network Information Center.
Chemical contaminants and pesticides in fresh or saltwater finfish, crustaceans, mollusks and other forms of aquatic animal life other than birds or mammals indicate potential hazards in human health. Topics included are control measures, FDA guidelines for federal tolerances and analytical procedures.
DHHS. FDA Center for Food Safety and Applied Nutrition.
Industrial chemicals, related chemicals and other chemical contaminants monitored by the FDA in relation to food safety and supply. Links to risk assessments of potential exposure to each chemical contaminant.
Chemical Contaminants in Food
Food Standards Agency.
Research programs that identify human exposure to contaminants present in food and its harmful effects. Research programs specified are emergencies involving chemical contamination, animal feed, chemical contaminants from food production, food contact materials research and mycotoxins and process contaminants, including acrylamide.
Chemical Contamination of Meat, Poultry and Egg Products
USDA. Food Safety and Inspection Service.
Includes sampling plans, national residue program data, lists of residue repeat violators, and residue related notices and directives.
Chemical Risks in Food
World Health Organization.
Adverse health affects could result from food additives and contaminants. Information links about global environment/food monitoring system, dietary exposure assessments and committees on pesticide residues and food additives can be found also.
Action taken by Health Canada in response to environmental contaminants being detected in food. Response measures include conducting risk assessments, reviewing standards and information on what you can do to reduce your exposure to these contaminants.
