Any deli meat that is stored cold for over 24 hours has the potential for a build-up of listeria that could be dangerous for the baby, regardless of whether it is straight from a deli or in your fridge. Don't eat it unless you have cooked it for long enough to kill any bacteria - if I get a craving for a toasted ham, cheese and tomato sandwich I cook the ham off in a frypan first.
