You've just finished an intense workout, and you reach for a cold bottle of water. The main one is government bureaucracy: Water is a consumable food product, and as such, it is subject to laws requiring expiration dates on all consumables, from bologna to lemonade.You crack open the seal and as you bring the bottle to your lips, you notice the expiration date says the water expired two months ago. Besides that, the expiration date on bottled water has certain benefits for the manufacturer.Zuckerbrot explained the three most common dates are Sell-By Date, Use-By Date, and Expiration Date. Sell-By Date: Refers to the last day a retailer can display a product for sale; typically a food is safe to eat for 10 days after the Sell-by Date if refrigerated properly.Use-By Date: Refers to the last day a product will maintain its optimum freshness, flavor, and texture.The FDA permits “reasonable variation,” meaning manufacturers are given a little leeway, so long as the any medication marketed in the United States contain between 90 percent to 110 percent of the amount of the active ingredient claimed on the label.“Just having the slight variation of 90 to 110 percent, well, it would be very difficult, from a manufacturing standpoint, to hone it down even more than that,” Dr.Lee Cantrell, of the California Poison Control System and UC San Francisco School of Pharmacy, told .
On "The Early Show on Saturday Morning," dietitian Tanya Zuckerbrot, author of "The F-Factor Diet," shared some advice for this dietary dilemma and what the dates stamped on food products really mean.
Finally, expiration dates are usually only one element of a printed code that also identifies the date, bottling plant, and other information.
Even though the expiration date itself is meaningless in terms of water going bad, the manufacturing information could be useful in tracking down contamination, bottling errors or product recalls.
Beyond this date, the product begins to deteriorate although it is still edible.
Expiration Date: Means what it says - if you haven't used a product by this date, toss it. So how do you know what is good and what is not safe to eat?
