Do 'Use-By' Dates Lead To Wasted Food?


First Posted: 06/ 2/11 12:05 PM ET Updated: 06/ 2/11 12:17 PM ET

Americans throw out 14 percent of the food they buy, and generate 34 millions tons of food waste every year. One way to reduce these numbers is by not strictly adhering to "use-by" dates found on food products. Scott Hurd, the director of the Food Risk Modeling and Policy Lab at Iowa State University tells LiveScience.com, "Officially I have to say, 'Don't use it after the use-by date,' but that's stupid. I use lots of food after the use-by date."

Even the USDA agrees with Hurd and says that use-by dates refer to best quality rather than safety.

There are many factors that can contribute to why a use-by date may actually be different than the date the product should actually be used by. A big factor is how much the product is handled and processed, and this varies by company.

The website Still Tasty, "your ultimate shelf life guide" allows users to enter thousands of products to see about how long they are good for in the refrigerator, freezer and pantry.

The charts below are USDA suggestions for when products are typically good for.

So, if the dates are just a guideline, how does one know when to eat and when to toss? Well, the powers of sight and scent are good ones - if the product looks okay, and it smells okay, it probably is okay.

if you are interested in this. Go take a university­-level microbiolo­gy class. It will scare you and you will throw food away like the educated do.

If it is slimy or smells off, throw it away.

I'm all for not wasting edible food. I have to say, however, that I believe fresh food is best. So for me, if I have beans, and I rarely eat them, and if the can is a year or so expired, I'll eat it. I just don't allow fresh veggies and meats to hang around long enough to go foul. Freeze things! And have a large container in your freezer for veggie scraps and bones to make a savory broth later.

I don't necessaril­y throw out something because its beyond the expiration date......­.. but then if the can is bloated or the item has turned green.....­...... that's a different matter....­......

When I find cans exploding on my shelf (and I recently cleaned a cupboard gunked up by exploding/­leaking cans . . .), I know I should have paid more attention to the dates on the bottoms. Some of those dates are years out from purchase date as it is.

I've never paid attention to the "use by" dates. As said in the article, they often refer to the products' maximum freshness, not their safeness to eat. I use sight and scent to determine whether or not to use it. If, for some reason, even after this, a product does not taste quite right, I immediatel­y dispose of it. I do not experience any digestive illnesses. Also, when one freezes a product, the use by date becomes useless. When it is thawed for use, the countdown really begins.

I was given 3 dozen eggs that were "past their due date" and just finished off the last of them recently. Likewise, the heavy cream in my fridge says it expired nearly a month ago and it's still fine. I expect to use that unopened package of fresh mozzarella which "expired" May 24, and the bag of refrigerat­ed shirataki noodles doesn't even have a date on it and it's nearly a month old. I lived off canned food that was well past its expiration date over the past two years and didn't die, either.

I find the recommende­d pull date for ham and bacon too short. They are cured and have lots of salt, which will preserve them longer. I keep bacon and ham in the fridge at least 3 weeks with no ill effects.

Eggs - 30 days after the expiration date on the carton. You can look it up. Dated can goods - local food-bank told me it will take contributi­ons dated up to one year after expiration date good enough for me. Meats and poultry - not more than a week in refrigerat­or when cooked. After cooking, freeze in freezer friendly leftover containers for up to a month. For uncooked meat and poultry, freeze uncooked portions within a day or two of purchase double wrapped in freezer friendly materials to avoid freezer burn which deteriorat­es presence more than anything.

I fed myself for one year on $75.00 per month to determine if I could. It was tight but I did it. The next year I raised the limit to $100 a month and came in at actually spending about $90.00 per month. But what a difference $15.00 per month made. One of the keys was what not to buy, which primarily was fast food and takeout. After all is said and done, it must be realized that a person has to live in an area where choice is available. The need for transporta­tion, and its costs, is inversely proportion­al to the distance to the purchase point. A person needs a means of preparing food, even a hot plate requires electricit­y. And lastly, a person needs a place and method for storage. The bigger the quantity purchased the lower the unit price. For the poor, it is not so easy.

Eggs usually have a "Sell By" date rather than a "Use By" date on them now.

That's why things that can be frozen and you're not planning on eating it anytime soon....FR­EEZE IT!

The smell test works, my aunt ate a sandwich made with recently expired ham and she got food poisoning. When I asked her she said that it smelled a little weird but that she ate it anyway... if it smells weird throw it away!

Very true!

I used to dump my eggs on the expiration date. Then one day I needed some eggs and the only ones I had were about two weeks past the expiry date. I was desperate so I cracked them in a separate container, did the sniff test, they smelled fine so I used them. Now I don't throw them away until I do a sniff test first. Eggs are expensive.­..at least to me.

I thoroughly researched this and uncooked eggs are good for 30 days after expiration date. Counter intuitivel­y cooked eggs only a few days. It seems when eggs are laid they have a natural film cover which serves to preserve them. This cover is removed in processing but is replaced before shipping. Boil an egg and the film cover is removes leaving the shell permeable.

Very interestin­g, I learned something new today. :) And I'm giddy to hear about the 30 day expiration date cause it usually takes me about that long to go thru a carton of eggs. Thanks for the info!

if something is over date but not yet bad cook it to be save.
12:15 PM on 6/03/2011
Isn't that the intention?

They need to make foods available in smaller portions. If I buy bacon, I'm not going to eat the entire package within a week!

For my family of four. We cut those packages of bacon in half instead of serving whole strips. It allows everyone to feel like they received more bacon than normal when really they didn't.

That's a really good idea!

I usually separate the bacon into serving sized stacks (usually 3 slices). I put the first stack on waxed paper, roll the waxed paper over it, then put on the next stack, roll it, and so on. I then wrap the waxed paper / bacon in foil and freeze until I need it. The waxed paper makes it really easy to remove just how many servings you need.

We are only two persons in this household. I divide a one pound package into four portions keep one in the fridge and the other three in the freezer. Taste wise it doesn’t make a difference after thawed.
