DDT was first evaluated in 1966 and has been reviewed several times since. At the 22nd (1990) and 23rd (1991) Sessions of the CCPR countries were requested to supply monitoring and other relevant data on DDT (ALINORM 91/24, para 77; ALINORM 91/24A, para 77). At the 23rd Session the existing Extraneous Maximum Residue Limits (ERLs) for DDT were converted to temporary limits awaiting evaluation by the 1993 JMPR. The 1993 JMPR proposed ERLs for carrots, eggs, meat and milks and the 1994 JMPR confirmed the existing TERL for cereal grains on the basis of the available data. The 1995 CCPR was informed that additional data on meat were available from Australia, New Zealand and the USA and decided to keep the proposal for meat at Step 3 pending the evaluation of these data by the 1996 JMPR. The 28th (1996) Session of the CCPR advanced all ERLs except that for meat to Step 8 (ALINORM 97/24, para 85).
The Meeting received national residue survey data on DDT in animal products from Australia (Anon., 1995a), Germany (Anon., 1995b), New Zealand (Anon., 1994; Jowett and Viggers, 1995), Norway (Anon., 1996), Thailand (Anon., 1995c) and the USA (Anon., 1995d) and on DDT in food of plant origin from Norway (Anon., 1996) and The Netherlands (Anon, 1995e). The Netherlands also submitted information on analytical methods and national MRLs (Anon., 1995e). Poland provided information on national MRLs (Anon., 1995f). The British annual report of the Working Party on Pesticides Residues for 1994 included information on DDT residues (Anon., 1995g). Residue data and information on the dietary intake of DDT were made available by the Global Environment Monitoring System - Food Contamination Monitoring and Assessment Programme (GEMS/Food) of WHO (WHO, 1996; Moy, 1996a,b).
