I wonder how much of the meds they give to cows comes through in their milk and hence into ABM. I also wonder how much of the insecticide/ herbicides get into cows milk from the stuff on the hay and grain they eat. I guess that OB that is worried about legalities isn't worried what the vet prescribed for the cow that made the ABM! Becky Behre Moscow, Idaho -Home to a big dairy science school, I'll have to ask!
