In the Asia/Pacific region, Australia’s tolerance levels for pesticide residues in fish are commonly referred to as extraneous residue limits, the term used specifically for pesticide residues arising from environmental sources other than the use of a pesticide directly or indirectly on food (FSANZ, 2006). In Japan, currently their residue tolerances are mostly available as provisional maximum residue limits (pMRLs). In establishing the pMRLs, Japan considered the Codex standards first. Where Codex’s standards were lacking, Japan used the mean value of the standards available from multiple countries. In the case of pesticide residues in fish, Japan’s pMRLs tended to rely heavily on U.S. FDA’s action levels.
