I just found this on the NHS website:
Meat and poultry
What you can eat
meats such as chicken, pork and beef, as long as they're well-cooked with no trace of pink or blood; be especially careful with poultry, pork, sausages and burgers
cold, pre-packed meats such as ham and corned beef
What to be careful with
cold cured meats, such as salami, pepperoni, chorizo and prosciutto (unless cooked thoroughly)
What to avoid
raw or undercooked meat
liver and liver products
all types of pâté, including vegetarian pâté
game meats such as goose, partridge or pheasant
So it seems in terms ok the UK, you should be fine with prepacked ham and beef. I have certainly been eating them in the past few weeks. We are lucky that the food safety standards in this country are very high, so things that you might be advised not to eat in other countries, even like America, may be okay.
