Searched more in to this today - There's a good read here (

High daily doses of very impure penicillin killed 95% of guinea-pigs within 3-4 days. When the purity was increased tenfold, 60% died. We now know that even these preparations were only 60% pure. This it is quite likely, and is actually suggested in the 1943 paper, that the impurities in the early samples of penicillin were responsible for some of the toxicity. The paper also went to great pains to emphasise that the toxicity of penicillin for guinea-pigs did not mean that penicillin was toxic for people:
“When treated with the same dose of penicillin per kilogram as the given to man guinea pigs did not die and, in fact, failed to show any signs of toxicity.”

Or, basically, the animal rights campaigners have neglected to point out that the conclusion of the study they claim shows guinea pigs die from penicillin refers to the impurities in the treatment, not to the penicillin itself.
