How Long Foods Stay Fresh In Fridge

ShopSmart Magazine's Lisa Lee Freeman Gives Fridge Shelf-Lives Of Many Common Items

  •  (CBS/The Early Show)

(CBS)  It's easy to put something in the refrigerator and forget about it.

But foods don't stay fresh in the fridge forever, and the day will come when you take something out and wonder if it's still good to eat or has gone bad.

On The Early Show Monday, ShopSmart magazine Editor in Chief Lisa Lee Freeman had the lowdown on how long foods last in the fridge.

ShopSmart consulted a panel of experts to determine which foods could be spoiling by just sitting in the fridge.

Freeman says it's not always the best idea to rely on labels. Some foods don't have them, and the ones on others can be confusing.

Also, most people don't realize that once they open certain popular items found in containers or cans, a new freshness clock starts ticking.

So, it's important to know which foods have a shorter lifespan once placed in the fridge.

If items that have been sitting in the fridge too long are eaten, they can lead to food poisoning and, in some cases, serious health problems.

BABY FOOD: LASTS 1 - 3 DAYS IN FRIDGE ONCE OPENED

An open jar of strained fruits and veggies lasts two-to-three days in the fridge. Opened cooked meat and vegetable combos need to go after a day or two. Meat and veggie combos should go after two days, tops. The bottom line: Don't leave open jars of baby food in the fridge longer than three days. A hidden danger with baby food is that parents may feed babies right out of the jar, so saliva transferred to the jar can promote bacterial growth when placed back in the fridge. If you're using a jar more than once, make sure you portion out what you're going to use, so the dirty spoon doesn't go back into the jar.

PASTA SAUCE: LASTS 5 DAYS ONCE OPENED

Once opened, tomato-based sauces are only good for five days to a week. Don't wait for the mold to form. In many cases, you won't see the mold in the sauce after five days, but it actually could be there. Some mold produce toxins that can be harmful, so why take the risk? Mold grows in very wet environments. What promotes the mold is the high moisture content. No amount of cooking will kill the toxins. So, to be safe, you need to throw it away.

MAYONAISE: LASTS 2 MONTHS ONCE OPENED

Mayo has a high fat content, which means it's not as susceptible to mold and bacteria growth. But the oils in mayo break down over time, so its flavor changes, and it will no longer taste good. There may be a subtle "off" smell, but you may or may not be able to smell it, so be on the safe side and dispose of it after two months, no matter what type of container it comes in. For other condiments, such as ketchup, oil, and salad dressing, refer to the expiration dates, which are normally accurate for these products.

Because it's not always easy to keep track of how long your food has been living in the fridge, Freeman suggests taking tape and a marker and writing down the date you open any glass jars or metal cans. Use the dates as your reference point. Once you've gone past the date, it is time to trash it!

CHEESE: LASTS 1 - 4 WEEKS

Softer cheeses generally have a shorter shelf-life than hard chesses. Hard cheeses ( e.g. cheddar or Swiss) last three to four weeks in the fridge after they're opened; soft cheeses (e.g. Brie) last one week. With cheeses, you can follow the "use/sell by" dates as your guide, but it's best to examine the cheese: Look for mold and smell the cheese to see if it has an odor of ammonia.

It's possible to prolong cheese's shelf life before you store it in the fridge: Remove the plastic that firm cheeses often come in, and wrap the cheese in wax paper. Finish it off with a light layer of plastic wrap.

It's also still possible to eat cheese that has mold on it, but you must be careful: Cut off an inch beyond the mold on all sides, keeping the knife clean between cuts, so you won't spread it. Re-cover it with some fresh wrap.

EGGS: LASTS 3 - 5 WEEKS

Eggs should last three to five weeks after you put them in the fridge. Keep in mind that it's very important that you don't put eggs in the front of the fridge — even if there are compartments for them there. They'll spoil earlier if they're in the front. Stick eggs along with milk, and raw food (fish, meat, and poultry) in the back of the fridge, because it's cooler there. Bacteria grow at a slower rate in colder temperatures. The back of the fridge is typically the coldest part of your fridge, so store items there that need to be kept freshest. Butter is good to keep in the front of the fridge, to keep it warmer so it's easy to cut. Butter, bottled water, and other unopened drinks are items that are less susceptible to temperature problems.

LEFTOVERS: LAST 3 - 4 DAYS

Kung Pao chicken, pepperoni pizza, or tuna salad must go in the fridge within two hours of serving to reduce your risk of food-borne illnesses, because bacteria grow more quickly at room temperature. Don't leave leftovers hanging out in the kitchen. Put them in the fridge as soon as you're done with them. Cold temperatures slow the rate of bacteria growth. For larger items, such as macaroni salad or large quantities of Chinese food, refrigerate in several shallow containers rather than large clumps. That way, the food will cool evenly and more quickly. You don't want a big clump: That risks the chance of something growing in the center because it didn't cool properly.

laura...if you and your kids (and presumably your grandkids) survived the "bad" ways that your dealt with food and leftovers, then why are you putting the list on your fridge? your good common sense got you this far--why not continue to rely on it? just because chicken little is running around in a suit screaming that the sky is falling doesn't mean we have to listen...

unless of course, you're putting the list on your fridge so you can get a good laugh now and then...

Ya know, I just wanted to post a good-natured crack about my "iron stomach" in this non-political article/forum, but there's mossmoonbat managing to scream his Bush hatred even here. Give it a break, moonbat, you'd blame Bush for moldy cheese if you could.

Anyway, what's with this cutting an inch off all sides of that old moldy cheese? There wouldn't be any left unless you started with a block about the size of a loaf of bread! I just scrape it off the surface, kinda like peeling a potato. Just think of that mold next time you order bleu cheese on your salad - that's what gives it its flavor.

just throw the remanders after opening for 1 meal in meal size portions baggies and throw in freezer. I question are these stories backed in any way by food industry? who want that pasta sauce purchasing every 5 days? Just freeze everything in smaller containers and zippie bags and never throw away again. keep your money without wasting. the food companies won't be happy, but who cares.

Im curious if any of the sources or contributors are relations to the food industry, of course they want you think pasta sauce goes bad in 5, means they will get money to feed themselves every 5 days. what you do is bag the sauce and throw in freezer in family size zippie bags! keep your money instead of food industry getting it.

I also think gucci805 is an idiot. He sounds like he is one of the 28% of Americans who think that Bush is not the worst President ever, but a hero. He is just one of the sheep. For historical perspective we impeached Nixon though had a better approval rating than Bush. Gucci805 a spell check is available on your computer (believing and our)By the way, if Potassium Sorbate is added you will increase the shelf life of products.

it amazes me that my daughters, who are now moms themselves, survived all the stuff we did or did not do that we should have-like not feed them from baby jars-they usually finished then anyway!

putting this list on my fridge.

I live alone and currently have no income; I'm living off savings. I guess I am going to have to eat ALL my meals AND SNACKS out.....
To think that my mother left a cooked roast or ham or stew sitting out ALL DAY SUNDAYS for us to just graze on throughout the day... She and my father lived to be in their 70's, my brothers and I have lived to see our 50's and 60's so far...
Okay, off I go to throw away the entire contents of the refrigerator so I don't get sick or die prematurely... ohhh, maybe I should sell the refrigerator, so I can afford more of that fast food I'll be eating forever until death do us part... now there's some food that should be investigated!!!!!!

It is obviouis that some of you are idiots. These are recomendations to help you be safe about your eating habits. Yes, sauce can last longer but to be safe, 5 days. Some of you need to get some common sense.

I have a simple question for the author:

where's your decreased life expectancy to corroborate this attempt at scaring the hell out of your readers/make more people waste more money?

it's practically a hobby in our home to take a lil gamble with the undercooked meats and the slightly stanky cheese.

wait, sorry, our cheese comes from mold to begin with, almost forgot. still, the bleeding meat, big time meal around here, has been in our family for.. centuries..

we're still hittin' the 70s and 80s for age.

For all of you disbelievers... CBS is reporting this because it is finally gaining greater scientific validation.

You may be able to give case reports of "people who grew old" eating mold - but you have to realize that there is a huge difference between the life expectancy since the depression and now (that is higher).

Also, remember that there are always stories of Grandpa living to be 90 and smoking 5 packs of cigarettes a day... Look at all of the ones who die from lung cancer or suffer disabling emphysema for years and dying sooner with that disease as well. Look at how long cigarette smoking was said to be not bad for your health.

It is clear that there are markers in a person's blood that makes them more likely to respond poorly to mold than others. There is a tremendous amount of research - and the fact is that mold is deadly and there are many studies that are actually linking mold to such diseases as cancer.

Keep you ears open as the studies are gaining greater merit and are being validated scientifically.

Don't say I didn't warn you (and no - I am not the author or any relation... just someone who has been affected and not yet found the cause of the mold - and guess what - there are tests that can determine if you suffer from mold toxicity)

WHAT HAS HAPPENED TO PLAIN COMMON SENSE? IF IT'S GREEN, CUT IT AWAY--IF IT STINKS, THROW IT AWAY. THIS IS THE DUMBEST ARGUMENT YET FOR THE TREE HUGGERS---GET A LIFE--IF YOU DON'T WANT TO EAT REAL FOOD, STAY AWAY FROM IT---DON'T TRY TO SCARE ALL THE NEWBIES INTO BELIEVINMG YOU KNOW EVERYTHING. YOU DO NOT---JUST ASK YOUR GRANDPARENTS--OR YOUR PARENTS--IF THEY HAVE SURVIVED OUIR DECADENT WAYS.

Danny Baldwin takes a piece of scotch tape and puts it across the use/sell by date on his food and writes "DRUGS" on it then immediatly shoots it into his arm...thereby making this whole article moot.

I'm getting very hungry, but I looked in the fridge and just found a note signed by "you know who". It said, "I've eaten your food and am now headed to the hospital to have my stomach pumped. Because the procedure is so painful, they will have to give me DRUGS!" Wooooo Hoooooo!" I mean..Sincerely yours.

News Flash: Daniel Baldwin has run out of drugs and now he wants to eat your old food. Don't try and resist, all he needs right now is a slight buzz. "Please pass the moldy cheese, thank you."
