Antibiotic creams

I was thinkin about this tonight about antibodies.
I worked in a meat packing plant about 36 years ago. Started at 2.00 hr. Thats not part of the story. thats another one.>LOL<
anyhow we had a shipment of hanging pork come in one time. I worked in the cutting room where we processed it. I was boning at the boning out table and I got a scratch on my hand from a pork bone. About a day or so went by and an infection set in. I went down to the plant nurse and she gave me some antibiotic cream to use on it. I trued it for a day or two and it would not work.
Soooo I went and got a can of bag balm. Bag balm is what they use on milking cows udder for this and that so an infection would not set in. I can not remember the ingredients. I put that on the infection and the infection went away.
I went back to the plant nurse and told her the antibiotic she gave me would not work. She asked me what I used as the infection was gone. I told her bag balm. She was sorta in a little bit of thats a new one on me. >LOL<
