A survey from the National Resources Defense Council found
that 90 percent of Americans toss out food prematurely. Much of this waste can
be attributed to a confusing food dating system that is not federally
regulated.
In fact, the United States Department of Agriculture
(USDA) states on its website that, with the exception of infant formula,
product dating is not required by Federal regulations. The food dates or
"expiration dates" we are so familiar with are actually not
indicators of food safety at all, they are simply the manufacturer's suggestion
as to when their product is at best quality.
What this means for the consumer is that we are most likely throwing out food while it's still perfectly safe to eat. The best way to combat
this waste is to familiarize yourself with common food labels and their
meanings. Below is a break down of the meanings behind these food labels, and general guidelines as to how long your groceries will actually last.
Since food labels refer to quality, not
safety, what are food labels telling us about the
quality of our food? And what's the difference between sell by, use by, best
by, and all the other labels?
Sell By
The sell-by date simply tells retailers how long to
display the product before taking it off the shelves. It's in no way an
indication of safety. Grocery stores will often try to get rid of this old
inventory through sales, so be on the lookout.
Best If Used By/Before
Probably the most commonly heeded food date is the best
by date, because, let's face it, the name is a little misleading. As with other
food dates, this label doesn't indicate when a product is "best" in
terms of safety, but rather in terms of quality. The best-by date simply refers
to when a product will be at best flavor or quality.
Guaranteed Fresh
This date usually refers to bakery items. It simply indicates
when the item will be at peak freshness, but it's still safe to eat after this
date.
Use By
This refers to the last date recommended by the
manufacturer for use of the produce while at peak quality. The only time this
refers to safety is in the case of infant formula.
Pack Date
The pack date is the code that refers to the date the
food was washed, graded, and packaged. This is most commonly found on egg
cartons. The tricky thing with this label is it's not the easiest to read. The
label will look like a three number code that represents the day of the year
that it was packed. For example, 001 would refer to January 1, and 365 would
refer to December 31.
Freeze By
This date indicates when a product should be frozen to
maintain peak quality as long as it's frozen.
How to Know If Food Has Gone Bad
These are general guidelines as to how long different
types of foods are safe to eat, the keyword here being general. What's most
important to know about food safety are the signs of spoilage.
According to the USDA, "If the date passes during
home storage, a product should still be safe and wholesome if handled properly
until the time spoilage is evident." Common signs of spoilage include an
off odor, flavor, or texture due to naturally occurring spoilage bacteria. Of
course, mold is also an indicator. But sometimes, even the sight or sniff test isn't enough
to determine whether or not food has gone bad. Refer to the chart below for
general guidelines from the USDA on when it's time to toss and when it’s not.
Keep Food Safe - Food Safety Basics
Safe steps in food handling, cooking, and storage are
essential in preventing foodborne illness. You can't see, smell, or taste
harmful bacteria that may cause illness. In every step of food preparation,
follow these four guidelines to keep food safe:
Clean: Wash hands and surfaces often.
Separate: Don't cross-contaminate and don't mix older foods with new ones.
Cook: Cook to proper temperatures, checking with a
food thermometer.
Chill: Refrigerate promptly.
