A lot of the information you find for micro specifications of food products pertains to human food and I am finding it hard to correlate some of it to animal feeds.
Salmonella is an easy negative but standard plate counts and coliforms are a bit more difficult. For instance, our current spec is less than 10 cfu/g for total coliforms. This is based on what we've seen from a similar human food.
I don't know if we are being too conservative with these values because I can not find good data on the micros for feeding cows. The other thing we consider is that humans are handling our products so we keep that in mind when we set our specs.
Any insights or suggested readings are appreciated.
Thanks for the help!
