I dont no if any got into there tank or not but they were discussing the difference between a infused quarter being milked and i geuss the sanitizing solution being used to clean a dirty jar between cows and it a getting let down into the milk line. But the farmer said he had a helper milk and infused quarter in to the tank with about 4,500 lbs of milk and it didnt test hot was curious because all i know about it is that its a sanitizer. Vet comes next tues. again for herdcheck get the whole story then, was just getting some meds and kinda easdropping , bad habbit when the convo involves cows.
