OK, another case of listeria hysteria, it wasn't on the forbidden list ten years ago in my
1st PG but now that it is, I've been pretty careful about it!

Listeria is one of those bugs that is heat sensitive, so I do sometimes zap a slice of ham in the microwave until it's sizzling and then indulge! Likewise for salami on your woodfired pizza. However, make sure it's super fresh. Same goes for other cold meat (ie left over chicken, roast meat, etc) make sure it has been stored properly and eat it the next day!

If you want some official reading, google Listeria food standards australia, and the 1st hit will be their guidelines on what to avoid and more importantly, what you can still safely have!
