To determine Use-by dates, samples of the food are monitored in a microbiology lab, in similar packaging and environmental conditions to those of the retail outlet and the home. Food scientists then test the samples for traces of known pathogens. The use-by date is calculated according to the point where levels of the microbes start to exceed safe limits.

What does a sell-by date identify?
In the United States, a "sell-by" date identifies the date by which the item should no longer be offered for sale. That should allow the consumer enough time to use the product. It is not an "expiration" or "use-by" date. If a store is still offering food that is beyond the "sell-by", I suggest you contact the local health department with jurisdiction.
