Explanation
During the Fourth Session of the Codex Committee on Pesticide
Residues, two questions regarding the previous recommendations of the
Joint Meeting were referred back for clarification. These questions
refer respectively to (1) the recommendation for a temporary tolerance
of 0.1 ppm on vegetables and (2) the recommendations for practical
residue limits in meat, milk and milk products.
RESIDUES IN FOOD AND THEIR EVALUATION
TOLERANCE RECOMMENDED ON VEGETABLES
The Meeting examined the broad group of crops which would be included
in the term 'vegetables' and, bearing in mind the caution contained in
the 1967 monograph in so far as fresh vegetables are concerned, i.e.
"from intentional and approved use and in no far as aldrin or dieldrin
have to be and are allowed to be used in individual countries on
specific crops within this category". It was agreed that the
vegetables to be covered by the recommendation should be as follows:
Asparagus Horseradish
Broccoli Lettuce
Brussels sprouts Onions
Cabbage Parsnips
Carrots Peppers
Cauliflower Pimentos
Cucumber Potatoes
Eggplant Radishes
Radish tops
Practical residue levels for milk, milk products and meat
On considering the suggestion from the Codex Committee on Pesticide
Residues that the practical residue limits for milk, milk products and
meat should be raised to 0.008, 0.2 (on a fat basis) and 0.3 ppm (on a
fat basis), various data from surveys in Australia, U.S.A. and the
U.K. respectively were considered. These showed that only a very small
percentage of the samples examined contained residues in excess of
those previously recommended, although it was recognized that some
samples might be found in practice to exceed the figures. It was
therefore decided not to alter the recommendation that had previously
been made.
