The following is an exchange of emails between a pet owner (O) and a pet food company (PFC) claiming to be producing cold-processed canned foods. The letters were sent to Wysong asking assistance in evaluating the claims.

PFC: "That means that the protein is cooked at the lowest temperature possible for the shortest amount of time to kill any bacteria yet without killing the enzymes. It helps the dogs actually simulate the protein instead of passing it."
O: "I am thinking of recommending your canned food to some of our customers. But before I do, if your patience still persists with me, I still need to understand your explanation of the protein being cooked at the lowest possible temperature to kill the bacteria … Please tell me what that temperature is that does not destroy enzymes yet makes it safe to eat canned food without the bacteria.

Several errors are made by PFC—
