Never thaw meat on the counter or let it sit out of the refrigerator for more than two hours. In the summer, reduce this time to 1 hour. Never defrost meat in hot water.

There are 3 Safe Ways To Defrost Meat:

* In the refrigerator
* In cold water
* In the microwave

Thawing in the Refrigerator-

As long as the refrigerator temperature is between 34° and 40°F, thawing in the refrigerator will be safe. Use a plate or pan under thawing meat to make sure dripping does not spill on foods, especially foods to be eaten without additional cooking.

After thawing in the refrigerator, ground meat should be used as soon as possible. Once meat has been frozen and thawed, it will deteriorate more rapidly than if it had never been frozen. Whole meat cuts (chops, roasts) will remain useable for another 3-5 days in the refrigerator before cooking.

Meat defrosted in the refrigerator can be re-frozen without cooking, although some quality may be lost. The USDA recommends that meat defrosted by other methods be cooked before refreezing.

Thawing in Cold Water-


Meat can be safely thawed in cold, not hot, water. Be sure to thaw meat in a leak-proof package or bag. Submerge the bag in cold water, changing water every 30 minutes so that is stays cold. It is important to keep the meat out of the food spoilage temperature range of 70° to 100°F.

After defrosting, refrigerate or cook promptly. Unlike meat thawed in the refrigerator, meat thawed by the cold water method should be cooked before re-freezing.

Thawing in the Microwave-

Meat can also be safely thawed in the microwave, although it may be more difficult to retain meat quality, especially if the microwave power is set too high.
Remove store wrap and foam trays before defrosting in the microwave. Thaw on low power so that microwave energy penetrates to the center of the meat. Most microwave ovens have a "thaw" setting and
may suggest an amount of time and turn schedule to prevent loss of meat quality. Meat thawed in the microwave should be cooked immediately after thawing

i thought you werent suppose to thaw in cold water anymore?:confused::confused:

Why's that Jeff?
Gosh that's the way I did it for years in a pinch (pre-veg days)--never killed us LOL

I used to take a roast or chops out of the freezer and immerse them in a sink of cold water for a few hours.

I tried thawing some meat in a sealed bag under running cold water. I did not like the way it came out. I think using one of those aluminum "thawing plates" sitting on the counter retains the meats freshness as it thaws much better. That's my experience anyway. Fish is a different thing. I have no problem with fish that's been thawed under running water.

I started to ask a question and was afraid, I'll do it anyway.

Here is my scenario, Suppose that you had a half chicken breast and two thighs. I make them flat and seal them in a FoodSaver bag. Then it is frozen. Now we come to the thawing.

While I understand everything that was posted above, I am not trying to start a war. I do not understand why it woul dbe wrong to plunk the whole sealed bag in a bowl of hot water. That amount of meat woul ddefrost tnough to put on a platter, season and be in th eoven in 20 minutes. Cold water would not be faster and partially thawed meat would be "out" longer. A microwave coul dpartially cook the meat or at the very least make the meat much hotter than the hot water method.

Again, I am not arguing, I am just trying t ounderstane why.

P. S. This all assume sthat the meat is cooked untill properly done and checked with a thermometer.

The reason is that you should not be taking the meat into the "window". I can't right now remember the numbers - something like between 20C and 63C. Food is not supposed to spend more than two hours in this zone - the zone of optimum bacteria growth.

The reason for cold water rather than hot water is that the cold water will probably not be in this zone and that the hot water will bring up the outside of the meat almost immediately into the zone while the frozen middle may take more than the two hours to defrost, thereby risking food poisoning.

Having said that, in your example the meat should be defrosted very quickly and this would not apply. It more applies to whole chickens & joints of meat.

Over here the official line is to defrost in the fridge.

I will say that I don't tend to, I use the microwave to defrost most of the way and then cook or leave in for about 30min/1hr before cooking of I leave the meat out overnight in a cool place and fridge it the next day.

Would the same not be true in a microwave?
I wouldn't think so Andy.
Remember, if you nuke something, it's already beginning to partially cook from the inside out, and it's quicker too, thus lessening the chances of bacterial growth.
That's my reasoning anyway.

I can understand what you said Mini. For a whole bird, or a larger piece of meat, averything makes perfect sense. I also agree, fridge is the way to go.

I understand the two hours in "the Zone". My problem is / was in the quick dinner scenario above, We are talking 30 minutes, tops.

I would personally say that is OK, so long as you cook it straight away - however the official food police will not like it (not referring to anyone on this forum - rather the government regulations)

Thank You Sass - I am just having trouble getting my mind around such a small quantity.

I don't want to get sick and I don't want to take unnecessary changes, just trying to understand.

Good discussion, this is an important subject and by getting ideas out those the rad this later and have their questions and some buts answered as well.

my mom uses those thawing plates all the time...the black ones like this one

and so far we havent been sick. she has been using it for about 15 years now.

I wouldn't want you to get sick either Andy.. otherwise you might need me to make a housecall.:brows: haha!!

Yep, good discussion and a very important one as well.:thumb:

Some of it relates to where you get your meat from - if the supply chain is really effective, the contaimination should be less. Also the cut of meat is important, the less exposed elements the better. Steaks & joints are better than ground beef.

The important thing (according to the food safety courxe I did) is the two hour window - less is better.

Ok, I’m with Adillo and need to try a little harder to get my head around this. If you defrost in warm water, or on the counter, or leave it out too long, I understand that outer skin temps can get about 40 degrees (F) and stay there until the core is defrosted. This is the bacterial play ground.

But, bacteria is killed at 160. So if you cook the meat to 175 or above, what happens then? It’s my understanding that nearly all food pathogens are killed at 160. Mad Cow is an exception since it is a protein folding deformity and no amount of heat can change that.

There is a two fold issue, one is ensuring that the food is cooked to a high enough temp to kill the bacteria. The second is that some of these bacteria produce toxins that can cause the illness. I need to find my food saftey course booklet so I explain more accurately.

As I remember the commonest forms of food poisoning are from post cooking, either cross contamination or leaving food over the two hour window.

I will be back.

Can't find my booklet. Here are a few websites with information on.

Now it appears that the key issue with defrosting is knowing that the whole thing is fully defrosted. This is so that you can be sure it all cooks. Now for a joint of meat, that does mean using a meat thermometer if you are not sure and making sure the whole piece is fully cooked. ie avoiding the undercooked turkey problem.
You can have the issue of bacteria leaving toxins in uncooked meat if you leave it out too long.

Most food poisoning is down to poor food hygiene & cross contamination and leaving hot food out too long without been cooled down fully or kept hot enough.

In terms of safety, I believe that it is best to thaw in the refrigerator as well. I do not like thawing in the microwave because it always partially cooks the meat and I do not like the change in texture.

You can have so much bacteria on the skin and at the surface that by the time you get the inner portion of the product to an appropriately safe temperature it can be too late. By the time the product is safe to eat (and indeed it may all be safe to eat eventually) you are no longer eating chicken, you are now eating chicken and about a trillion dead microbes.:glare:

Or it is so overcooked that it has become inedible--tough and dry.

Interesting. Actually, the first thing that popped into my head wasn't chicken since it defrosts quickly and can be done fast and safely. No. Larger cuts like a Boston Butt. A Boston Butt you will run up to an internal temp of 200 - 205 where it shreds nicely. It's one of the few meats that benefits from high internal temperatures, but it is also a huge hunk that takes forever to defrost.

Alot depends on bacteria/pathigen load. Yes, 160 or so kills bacteria and most pathogens. But there is a time component as well. So, a fresh piece of beef may only require a few minutes at 160, a heavily loaded piece may require much longer.

Secondly, a heavy dead bacteria/ pathogen load will alter taste, even if all the little bugs are dead. To wit, you could cook dog chit for four hours killing every possible living th9ng in it, and would be perfectly ok to eat - would you?

To all of you who defrost on the counter overnight - count your blessings. It is not if you will end up with a pathogen driven disease, but when. I've said it before - spend a week in the hospital, and a few months delivering stool samples to the health department, and you'll see the value of "when in doubt, toss it out".

Defrost in the refrigerator. Keep your refrigerator below 40f. Keep your freezer below 0f. If you need a quick defrost - use the defrost mode in the microwave. You can use cold water for mid-range defrosting, but the water needs to be 40f or colder. Air defrosting is courting disease.

Nuff said! Waybomb wins the internet!!! :yum: :thumb:

Big items I defrost in the fridge. Smaller items I do in water (30 minutes or less). I never deforst hamburger in water as it gets too slimy (oily) to work with unless you're making curmbled beef. Since I only cook for two, and freeze for two, I do most defrost in cold water, and like I said, it's done in 30 minutes or less. I also keep a digital thermometer in the fridge, and look at it daily. It's a constant 37 degrees.
