Methods: The fresh milk samples of 35 farms in Beijing and Hebei districts, as well as the feed and production water as inputs from 3 large-scale farms in Beijing were collected to carry out risk monitoring of lead pollution based on the distribution of farms in these two districts. Results: There were no exceeding the standard limit requirements of lead contents in 52 feed samples and no lead detected in 6 water samples from 3 farms in Beijing district. The qualification rate of feed and water samples was 100%. The qualification rate of 35 fresh milk samples from farms in Beijing and Hebei regions was 100%. Conclusion: The farm inputs of Beijing district was safe, and there was no significant lead pollution in fresh milk from farms in Beijing and Hebei districts.
