If you really have no idea how warm the roast got and for how long, you're better off discarding it. You have no idea what bacteria and toxins may have developed.
It depends on the food, but in the grocery store where I work we have to throw frozen meat out within three hours of losing power. If you are planning to cook the meat right away it should still be good. Especially if the meat is still cold. If kept in the fridge it should be okay for another day or two.
No. Any meat that is left out for more than three hours should definitely be thrown away. When the temperature of food stays above 41 degrees, that's when bacteria starts to grow and it spoils. You can get a few hours out of it, but definitely not overnight. Same if it was frozen. Always thaw frozen foods in the refrigerator or in an ice water bath.
Yes, you can still cook perogies if they thawed out while frozen, as long as they were thawed safely in the refrigerator and not left at room temperature for too long. Simply cook them according to your preferred method—boiling, frying, or baking. However, if they were thawed at room temperature for an extended period, it's best to discard them to avoid food safety risks. Always ensure they are heated thoroughly before serving.
Unless you live somewhere that the inside of your car stays at least as cold as the inside of the fridge, this is probably a bad idea. They could have dangerous bacteria levels that are not even creating a bad smell yet. The exception to this is may be if they were frozen and were still quite cold when you retrieved them.
This is inadvisable.
No.
Maybe not for eating, but it can be used as a paperweight
Sniff it. Butter gone bad will have a rancid, stinky smell. If it still smells sweet, it's good to eat.
Frozen chicken nuggets should not be left out at room temperature for more than 2 hours. Bacteria can start to grow rapidly between 40°F and 140°F, known as the "danger zone." To ensure food safety, it is best to thaw and cook frozen chicken nuggets according to package instructions or store them in the freezer until ready to use.
the giblets still cook and you can open the bag and eat them
Yes actually you can because my son did it.
It is not safe to consume frozen meat that has been left out for 12 hours. The meat may have reached unsafe temperatures and could be contaminated with harmful bacteria. It is best to discard it to avoid the risk of foodborne illness.
