TRICHLORFON
Chemical names: DIMETHYL (2,2,2-TRICHLORO-1-HYDROXYETHYL)PHOSPHONATE
Synonyms: METRIFONATE
Functional class: VETERINARY DRUG (INSECTICIDE)
Latest evaluation: 2003
ADI: 0-0.002 mg/kg bw
Comments/MRLs: The MRLs recommended at the fifty-fourth meeting (2000) were not reconsidered at the sixtieth meeting (2003). MRLs (expressed as trichlorfon, in mg/kg tissue, mg/l milk): Muscle, liver, kidney, fat and milk (cattle): 0.05. At the fifty-fourth meeting (2000), the Committee noted that the concentrations of residues were very low in muscle, liver, kidney and fat. These MRLs are for guidance only and are based on the limit of quantification of the analytical method.
Report: TRS 918-JECFA 60/26
Residues: FNP 41/13-JECFA 54/103 (2000)
