Research Progress of Lead Contamination in Animal Food and Corresponding Control Technology for Feed

Lead is one of the most toxic substances to animals and human. Lead in environment could be accumulated in animal food through food chains such as feed or water, and result in problems of food safety. The sources of lead pollution, lead metabolism and factors in animals, and lead contamination in feed and animal products were reviewed in this paper. In addition, methods of feed control technologies to decrease lead content in animal products were also discussed. Moreover, future research directions were proposed.
