@entity10687 is a widely used @entity5139 pesticide in agricultural crops (including food) and animal feeds in China, resulting in heavy contamination. Many studies have focused on the food-processing effects on @entity10687 removal, but sufficient information is not observed for feed-processing steps. Here, @entity10687 residual behaviors in field crops and its transfers in @entity4186 pellet feed-processing steps were evaluated. In field trials, the highest residues for @entity579 grain, shelled @entity4336 , and @entity1460 seed were 12.0, 0.605, and 0.220 mg/kg, respectively. Residues of all @entity579 grain and about half of shelled @entity4336 exceeded the maximum residue limits (MRLs) of China, and five @entity1460 seeds exceeded the MRL of China. @entity10687 residue was reduced 38.2% in brown @entity579 after the raw @entity579 grain was hulled. The residue in bran increased 71.2% after milling from brown @entity579 . During the squashing step, the residue reduced 73.8% in @entity1460 meal. The residues reduced significantly (23.7-36.8%) during the process of granulating for @entity579 , @entity2829 , and @entity1460 products. Comparatively, the grinding process showed only limited influence on @entity10687 removal (<10%). The residues of @entity4186 pellet feeds produced from highly contaminated raw materials of this study were 1.01 mg/kg ( @entity2829 - @entity1460 feed) and 3.20 mg/kg ( @entity579 - @entity1460 feed), which were much higher than the generally accepted value (>0.1 mg/kg) for animal feeding. @entity10687 residues were removed significantly by processing steps of pellet feeds, but the residue of raw materials was the determining factor for the safety of @entity4186 feeding.
