Correct me if I'm wrong but I thought fritz or polony or devon (different names for different states in Australia) was slightly carcinogenic. DH was a butcher and he told me I would never eat fritz if I saw it being made (he never would tell me what it was made from though). We had it as kids, my kids enjoyed it as do my GKs but I never have it myself now because of this reason and I wouldn't give it to my GKs either. Pop dogs are also off the menu for me, in fact, I guess I could say all manufactured meat is off the menu. Not sure if sausages fit this category, probably not but goodness knows what goes into them.
