Penny S... Nope. I was worried about just what michaelr said I should be worried about in this particular case. Fact is, rendering the carcass would kill any and all bacteria BUT, if any bacteria WAS growing, their byproducts could cause severe intestinal discomfort... known hereaboutst as "The Shits". I wouldn't take that chance with me mum. Yes, it's a slight chance, but slight don't cut it with an 85 year old frail woman.
