Expiration Dates

Certain items in your house practically scream "toss me" when their prime has passed. That mysterious extra white layer on the Cheddar? A sure sign it needs to be put out of its misery. Chunky milk? Down the drain it goes.

But what about that jar of olives or Maraschino cherries that has resided in your refrigerator since before the birth of your kindergartner? Or the innumerable nonedibles lurking deep within your cabinets and closets: stockpiled shampoo and toothpaste, seldom-used silver polish? How do you know when their primes have passed?

With help from experts and product manufacturers, Real Simple (http://www.realsimple.com/) has compiled a guide to expiration dates. These dates are offered as a rough guideline. The shelf lives of most products depend upon how you treat them. Edibles, unless otherwise indicated, should be stored in a cool, dry place. (With any food, of course, use common sense.) Household cleaners also do best in a dry place with a stable temperature. After the dates shown, beauty and cleaning products are probably still safe but may be less effective.

Food

Beer

Unopened: Starts to lose flavor after 110 days.
It’s best to store bottles in boxes, and then in dark place.
Stronger alcohol and higher levels of hops might extend the shelf life of a beer.
One example is Michelob Craft Specialty beers, which are often at their peak with 180 days.

Learn the Lingo of Expiration Dates

The actual term "Expiration Date" refers to the last date a food should be eaten or used. Last means last -- proceed at your own risk.

More commonly spotted terms are:

  • "Sell by" date. The labeling "sell by" tells the store how long to display the product for sale. You should buy the product before the date expires. This is basically a guide for the retailer, so the store knows when to pull the item. This is not mandatory, so reach in back and get the freshest. The issue is quality of the item (freshness, taste, and consistency) rather than whether it is on the verge of spoiling. Paul VanLandingham, EdD, a senior faculty member at the Center for Food and Beverage Management of Johnson & Wales University in Providence, R.I., tells WebMD the "sell by" date is the last day the item is at its highest level of quality, but it will still be edible for some time after.
  • "Best if used by (or before)" date. This refers strictly to quality, not safety. This date is recommended for best flavor or quality. It is not a purchase or safety date. Sour cream, for instance, is already sour, but can have a zippier, fresh taste when freshly sour (if that's not an oxymoron!)
  • "Born on" date. This is the date of manufacture and has been resurrected recently to date beer. Beer can go sub-par after three months. "It is affected by sun," VanLandingham says. The light can reactivate microorganisms in the beer. That's why you have to be especially careful with beer in clear bottles, as opposed to brown or green.
  • "Guaranteed fresh" date. This usually refers to bakery items. They will still be edible after the date, but will not be at peak freshness.
  • "Use by" date. This is the last date recommended for the use of the product while at peak quality. The date has been determined by the manufacturer of the product.
  • "Pack" date. You will find this one on canned or packaged goods, as a rule, but it's tricky. In fact, it may be in code. It can be month-day-year-MMDDYY. Or the manufacturer could revert to the Julian calendar. January would then be 001-0031 and December 334-365. It gets even weirder than that.
