I think the OP meant when they cook pork chops for themselves. At least that's what I thought they were referring to.
Allie, the whole trichinosis debate has been beaten to death over the years. I remember having the debate myself over on DF years ago. At the time not one person could give me any proof that any poisioning or illness related to trichinosis had actually ever occurred here in Australia. As a matter of fact it has been claimed that Australia is not even included in the list of those countries where trichinosis poisioning is a threat or risk, due to Australia's stringent control of pork meat.
So in the end many ppl avoid feeding pork to their dogs because of a belief which is (in my opinion) a complete load of crock. If anything, ppl who don''t feed pork to their dogs choose not to simply because of the fat content and the richness of the meat, which causes some dogs problems. That's why I suggest that ppl feeding pork do their research on it first. For a basic example, dogs susceptible to pancreatitis should not have much pork, if at all. Some dogs will have mild diarrhea, others will be chronic, some will vomit and froth at the mouth a lot, others will have mild digestive reactions. A lot of those reactions though possibly relate to how much pork was fed in any one given meal. Same thing for a lot of dogs regarding the feeding of offal - too much and you will find the same systems.
ETA: Symptoms - NOT systems. Duh.
