What's the difference between best before and expiry date?

Chef's answer
Expiration dates tell consumers the last day a product is safe to consume. Best before date on the other hand tells you that the food is no longer in its perfect shape from that date. It may just lose its freshness, taste, aroma or nutrients. It does not necessarily mean that the food is no longer safe to eat.

They will be fine, don't worry, keep an eye on them, we eat out of date food all the time. You just have to use your common sense. Heavily processed food like rich ones sausages are the safest if not the healthiest food.10 Aug 2017
Use by dates are there because a lot of people cannot tell when something is spoiled. If you cooked something until is has piping hot throughout (which you WOULD do with sausages) and the food wasn't discoloured, smelly, slimy or had white bumps of mould growing on it... most likely you will be just fine.9 Jul 2010
