Antibiotics does not affect the setting of milk with rennet

The same of course does not hold true for cultures used in cheese making, since they are bacteria as well – so the antibiotics will kill the good bacteria as well. Rennet is an enzyme, so not affected by antibiotics. The reason the milk is blue in the video, is because I used antibiotics used to treat udder infection in cows, so the antibiotic is dyed to see if it is still in the milk.
