How Long Foods In Fridge Stay Safe To Eat

(CBS)  Have you ever looked in your refrigerator and wondered, "Has this food gone bad?"

Tips to help you know were offered on The Early Show Monday by Amanda Walker, Senior Editor of Consumer Reports' ShopSmart magazine. She outlined how to know which foods should stay and which should go.

Whether it's leftover chow mien, moldy Muenster, or an open jar of pasta sauce, foods' shelf lives vary once you open and store them in your refrigerator.

MILK: LASTS NO MORE THAN A WEEK AFTER THE SELL BY DATE

Keep milk in the back of the fridge, and toss it no more than a week after the sell-by date. This is one item where you can use the "smell test." Don't put milk on the refrigerator door. Save the door for items you want to be a bit warmer, such as butter. Bottled water and other unopened drinks are items that are less susceptible to temperature problems. Many condiments, such as pickles and olives, have highly acidic brines that slow bacterial growth, so you can keep them for a long time, until you see mold forming.

MAYONAISE: LASTS TWO MONTHS ONCE OPENED

Mayo has a high fat content, which means it's not as susceptible to mold and bacteria growth. What does happen is that the oils in mayo break down over time, the flavors change, 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 (this is for any container -- glass or squeeze bottle). 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 so easy to lose track of how long your food has been living in the fridge, take tape and a marker and write down the date you open the item. Use that as your reference point.

PEANUT BUTTER: REFRIGERATE AFTER THREE MONTHS

Peanut butter in the cupboard is a good thing to mark, because regular peanut butter doesn't need to be refrigerated until it's been open for three months, at which point you want to put it in the fridge. Natural peanut butter, however, should be refrigerated after you open it.

BABY FOODS: LAST ONE-TO-THREE DAYS IN THE 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 is: Don't leave open jars of baby foods in the fridge longer than three days. Another hidden danger with baby food is that parents frequently may feed babies right out of the jar, and 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.

LEFTOVERS: LAST THREE-TO-FOUR 4 DAYS

King 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. Refrigerate larger items like macaroni salad or large quantities of Chinese food 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 means taking the chance of something growing in the center because it didn't cool properly.

Fridge are only to kept any leftovers for three days, or if you are not going to use your leftovers for a week it should be kept in the freezer and should be heat up as if you are recooking it. Children should not eat any leftovers at all from the fridge or freezer.

as a 60ish male, i am the oldest of 4 siblings. back in those days, as low income blacks, we ate a lot of leftovers and we very seldom threw anything out. most of what you said was common sense.........which nowadays, does not seem to be a lot of "that" around. still the smell or taste test still works! great advice! hope more young people will read this and adhere to it!

wait is this Douglas Wilson as in the postmillenial, presuppositional, federal-visionist-but-otherwise-awesome guy? If so, loved the talk at the Minneapolis conference. if not, then you just probably think I'm crazy.

Huh...this story directly conflicts with my theory that if it doesn''t actively try to evade your hand it is probably still safe to eat.

After a little scraping, anyway.

I knew a farmer/rancher that had a cow he pampered.

The cow gave spoiled milk.
(that''s a joke - for the writer''s strike)

I use a vacuum sealer on most items, and have had incredible satisfaction with that. Try one. They are especially good in the freezer, freeze liquids first, then seal the next day in solid form. I was able to eat frozen cioppino after a year, turkey soup two years later, delicious and safe....

"Stomach flu" is really food poisoning in disguise. People who frequently get "stomach flu" should read this and pay good attention. And if you haven''t cleaned out your frige in the last week or so, food-borne illnesses are being passed from one bad dish to your milk, your meat, your tuna salad, and whatever else you have in there. Whenever your frige kicks on, it''s blowing contaminated air all over the inside, and all over your freezer, too. That bowl of pudding could be a bowl of puking if you aren''t careful.

This is a bunch of hooey.

That last about peanut butter is a good point--how many of us leave the open jar back in the cupboard for the YEARS it takes to use it up???
