Hello, please, I would like to know if the meat freshly put in a freezer of the kitchen, is able to undergo a putrefaction (blue color and smell of relent) in just 2 to 3 days after? !!! because this is a case that I have just found personally and I really do not have any explanation for it and even veterinarians do not know why ..., is this putrefaction due to an action of bacteria or enzymes that work at low temperatures from -10 to -17 C?! The animal sacrificed (sheep), was it doped with hormones or other substances before its death to cause this putrefaction? Thank you
