The U. S. Dept. of Agriculture (USDA) advises: Once food is thawed in the refrigerator, it is safe to refreeze it without cooking, although there may be a loss of quality due to the moisture lost through thawing. After cooking raw foods which were previously frozen, it is safe to freeze the cooked foods.
The short answer is yes, but there are a few things to keep in mind. First of all, the quality of any food is affected when you freeze it for a second time. That's because slow freezing introduces large ice crystals that damage the cells of the food once it's thawed — the culprit behind “mushy” meat or fish.
If you refreeze the food after it has been defrosted, the ice crystals will form again, but they may be smaller and not as effective at preserving the food. This can lead to the growth of bacteria and other harmful microorganisms that can cause food poisoning and make you sick.
The biggest downside of freezing and thawing and re-freezing and re-thawing is that the food becomes excessively mushy. Most food contains water. When you freeze something, the water inside expands, and the cell walls break down, leading to unrecognizable mush, says Ramsey.
If you refreeze the food after it has been defrosted, the ice crystals will form again, but they may be smaller and not as effective at preserving the food. This can lead to the growth of bacteria and other harmful microorganisms that can cause food poisoning and make you sick.
You should defrost your food in the fridge so that it doesn't get too warm, see our Danger Zone info below for why this is important. It's also important to use food within 24 hours after it's been fully defrosted – it will go bad in the same way as if it were fresh.
The more you freeze the food, the more the tissues break down, the flavor profile decreases and moisture escapes. For example, some vegetables, like green beans, will become mushy if it is thawed and frozen multiple times. They are still safe to eat, but the texture may not be as desirable.
Yes, thawing and refreezing frozen food multiple times can increase the risk of bacterial growth and foodborne illnesses. Each thawing and refreezing cycle allows bacteria to multiply. It's safer to thaw food in the refrigerator and cook it promptly.
Never thaw food in a garage, basement, car, dishwasher, plastic garbage bag, in hot water, out on the kitchen counter, outdoors or on the porch. These methods can leave your foods unsafe to eat. For safe thawing methods, see: The Big Thaw.
It's safe to defrost and refreeze meat again and again, provided you do it properly. However, what will begin to happen with repeated freezing and thawing is that the meat will become dryer and less tasty, says Donald W.
Store ready-to-eat foods such as cooked meats, pies and dairy products such as cheese, butter, cream and yoghurt in the top part of the fridge. Covering and wrapping food stops harmful bacteria from being passed from raw foods to ready-to-eat foods. It also stops food from drying out and becoming stale.
According to the U.S. Food and Drug Administration, as long as the shrimp were thawed properly in the refrigerator or in cold water, it is safe to refreeze and rethaw them. The maximum time they can be held at room temperature is 2 hours, total, over the course of thawing and refreezing.
So thawed food will have some bacteria that can multiply at room temperature, meaning that if the food is refrozen, there will be an increase in bacterial count by the time it is thawed again. This becomes a non-issue if the thawed food is reheated to an internal temperature of 75 degrees C.
These principles apply to meat, poultry, shellfish, some vegetables and cooked foods. Do not refreeze ice cream and similar frozen desserts. You can cook and eat thawed but still cold food mixtures like casseroles, pot pies, frozen dinners or pizzas but do not refreeze them.
Once food is thawed in the refrigerator, it is safe to refreeze it without cooking, although there may be a loss of quality due to the moisture lost through thawing. After cooking raw foods which were previously frozen, it is safe to freeze the cooked foods.
Refrozen food has a higher risk of causing food poisoning because when food is re-thawed, bacteria can multiply rapidly. However, if you cook defrosted food - for example turning defrosted chicken into a chicken curry - harmful bugs will be killed off, making it safe to refreeze.
Food that is stored in a freezer at zero degrees will be safe to eat indefinitely. However, if meat is frozen too long it may lose quality and taste. If you are unsure if meat is still fresh, you can determine this once it has been thawed.
Water expands when it freezes, so the freezing, thawing, and re-freezing of water over time can cause significant damage to roadways (e.g., the formation of potholes), sidewalks, and other outdoor infrastructure.
Can you refreeze meat after thawing? Refrigerator-thawed, raw or cooked meat is safe to refreeze, though the U.S. Department of Agriculture warns the meat may lose some quality due to moisture loss.
As the meat freezes and thaws repeatedly, ice crystals form and expand within the meat, causing the meat fibers to break down and creating spaces for bacteria to grow. Additionally, each time the meat is thawed, the temperature rises, creating a warm environment that is ideal for bacterial growth.
As freezing stops bacterial growth, cheese can be frozen for quite a long time – but we recommend using within six months. Beyond this the cheese's taste and texture can be very significantly altered.
Once you have defrosted your freezer and switched back on the power, you can store frozen foods straight away. It is only in the case of new freezers that you must wait a number of hours before storing frozen foods (you should consult your manufacturer's handbook for more information).
The longer food sits out, the higher its risk of growing harmful bacteria. However, placing hot foods straight into the refrigerator might raise the appliance's ambient temperature, putting the foods inside directly in the "danger zone" for bacterial growth.
While foods are in the process of thawing in the refrigerator (40 °F or less), they remain safe. After thawing, use ground meats, poultry, and fish within one or two additional days, and use beef, pork, lamb or veal (roasts, steaks, or chops) within three to five days.
