S.G.
I have never had a food borne illness that I know of. I suppose a few of the times I have had a bad stomach virus it could have been food borne. I do buy meat that is on clearance because it is close to the sell by date and freeze it. I managed a restaurant for many years so I have food handler training and I am pretty careful with meat. I never thaw at room temperature, always in the fridge or under cold running water. I am careful about cross contamination and cooking temperatures.
For many food items I do not go by the "sell by" or "use by" dates alone. Most food items do not magically go bad on the date marked on the package.
