The established tolerances are for DDT, DDD, and DDE. Tolerance for other pesticides is still zero, but tolerances for those may be estab lished soon. The tolerance for each or any combination of DDT, DDD, and DDE is 0.05 parts per million (ppm). This means less than one ounce in a million pounds of milk. Tolerance on a milk fat basis is get the milk fat down to the estab lished tolerance of 1.25 ppm would require about 20 weeks. One accidental exposure of cows to a freshly sprayed crop could result in contaminated milk for five or six months. The economic loss makes it essential to avoid even one accidental intake. To be competitive today, farmers need to use pesticides and they are.. According to USDA reports, farm ers spent 456 million for pesticides in 1964. This was about $300 per farm.

Likewise, any accidental contamination of feed or milk still must be avoided. Drift from nearby fields still would cause contamination. Research has shown that one feeding of a contaminated feed causes problems for weeks. When feeds containing DDT are fed to dry cows, milk produced later will be contaminated. Arizona research showed that re moving DDT contaminated feed for 30 days before calving did not help. In this study, the milk fat con tained 200 ppm the first week after calving. At 37 weeks after calving, the milk fat still contained fi.S ppm. The amount of DDT in the feed in fluenced the level and length of time DDT was in the milk. But, this work definitely shows that con taminated feeds should not be fed to diy cows. The work above was done when feed containing DDT was fed for GO days. A more recent report shows that a single dose also must be avoided. In this Arizona study, DDT was mixed in grain and given at one feeding. About V?i ounce (8.5 grams) was given to mature cows.
