We have a milker on pen. Trying to find withdrawal for people. Also...curious about using this milk for kids. My first instinct is that it woudl be fine to pasteurize this for the lambar, but then I read "Penicillin G is distributed into milk; in food animals the distribution is sufficient to cause violative residues. However, (label dose) the concentrations of penicillin produced in milk are subtherapeutic for most bacteria. In sheep, 0.11% of an intramuscular injection of sodium penicillin G was distributed into the milk." So I wonder...will the small amts of residual pen left in milk create a risk for antibiotic resistance?
