Is it bad to eat cheese after its expiry date?
Speaking in general about expiry dates, because I haven't seen them posted in other answers to this or other questions...

Expiry dates are (in some jurisdictions) entirely optional for most goods, and determined by the manufacturer (one example, anecdotally).

Another recent-ish article, which I found enlightening, from National Geographic that suggests that strict adherence to these "dates" results in wasted food that's perfectly safe. There's no doubt a balance between economics... and helpful suggestions for general health/safety.

There's clearly also examples and counterexamples: food that's spoiled before the expiry date because of poor storage, contamination, etc.; unopened shelf-stable food that might be safe indefinitely.

Plenty more questions about this topic, in general, also by searching SA for "expiry" and/or "expiration" in addition to the other suggested search topics. 

Be safe out there! :)
