51 move home with a few chickens and ducks in the fridge, forget to eat, now in November, suddenly recall it, afraid of cold for a long time to eat bad stomach, consult an expert can not eat?
According to the national standard GB16869-2005 and the standards of the relevant production enterprises of fresh and frozen poultry products, frozen meat products of poultry and ducks can be stored in a frozen warehouse below -18 degrees Celsius, with a shelf life of 12 months. In that case, there's no problem eating. Only for a long time storage, nutrients will be a lot of loss, taste is not good.
Too long frozen food, if the food does not go bad, is theoretically edible. The reason why food cannot be eaten is because the nature of food has changed and some harmful substances have been produced. For example, bad food is likely to produce toxins harmful to the human body, people eat such food poisoning. And you said the frozen ducks and ducks for a long time (half a year), according to our existing scientific point of view, minus 18 degrees of animal body for six months will not degenerate. In other words, you should be safe to eat, not because of eating these chickens and ducks have adverse effects. But the long frozen food has no fresh food, and it will taste worse.
Can eat, only taste is not good. Think of a living person who can't eat or drink for less than O degrees Celsius and live for decades
