In the meantime, what may be complicating the fish consumption issue further is the potential for misuse or mistreatment of the fat-based Codex MRLs. As pointed out earlier (Slide No. 13), the Codex Alimentarius Commission has not yet provided any MRLs for OCPs in fish. For OCPs in meat other than marine mammals, the commission sets the MRLs on fat basis by adopting a daily fat intake of 50 g (e.g., JECFA, 2006) from their standard diet assumed for meat eaters. As expected, their focus on fat basis is built upon the notion that due to their great lipophilicity, OCPs (and other POCs as well) tend to concentrate and stay in fatty tissues.
