Japan’s Consumer Affairs Agency (CAA) has proposed new maximum residue limits (MRLs) for the veterinary drug prallethrin in various animal-derived food products, as part of ongoing revisions to the Food Sanitation Act. This initiative is aimed at enhancing food safety by regulating prallethrin levels based on scientific risk assessments and international standards

The proposed MRLs include:

0.2 ppm for cattle and pig muscle
3 ppm for animal fat
0.05 ppm for eggs
These limits are designed to ensure that residues of prallethrin—commonly used in veterinary applications—remain within safe thresholds for human consumption. The CAA’s proposal is grounded in Japan’s Positive List System, which prohibits the sale and distribution of food products containing agricultural chemical residues above approved levels unless specific MRLs are established

The draft regulation has been notified to the World Trade Organization (WTO), inviting international feedback during the public comment period before formal adoption. This step reflects Japan’s commitment to transparency, global harmonization, and consumer protection in food safety governance
