Use-by dateWe’ve written before at HuffPost UK about how properly frozen food never technically goes off, though the taste and texture are likely to become pretty impaired after months in ice. Even non-refrigerated veggies like potatoes can last for half a year if “cured,” too.But what about leftovers from food which was cooked on its last viable day? If I cook, for instance, yellow-sticker chicken on its “use-by” date, will I be able to safely consume it next lunchtime?Here’s what the experts say. Cooking extends food’s safe limit The Food Safety Authority (FSA) tells us, “You can eat food past its use by date if it is cooked or frozen.” This is because “cooking kills any pathogens in the food and gives you a little more time to use it up.” Their site says you can cook raw food until midnight on its use-by date. Once it’s cooked, they add, you have to eat or freeze it within 48 hours.Bu
