I don’t know about you, but I’m growing wary of expiration dates. Reach for the Tylenol in your medicine chest, and it seems that the expiration date on the bottle has just come and gone. Same with a tube of Neosporin, a container of Airborne, or a sheet of cold tablets. Same with eye drops and rubbing alcohol. Same with vitamins. And these are non-prescription items. Prescription ones are even worse.
A doctor’s prescription is only good for a year – and I can understand that, given the all-too-frequent abuse of prescription drugs. But once you have a tube of prescription face cream in your possession, is there a problem using it past the “discard after” date on the label? Is it about potency – that the strength decreases with time? Or simply that when you toss the old one, you have to buy a new one, which means more money for manufacturers and vendors?
What made me think about this was the Thanksgiving holiday, when my son was home and looking for mayo in the fridge. There was an unopened bottle … whose expiration date was last month. He chose to use mustard on his sandwich instead. So, was there a danger in using the mayo? Had it gone bad by the expiration date, even if the bottle hadn’t ever been opened?
What about bottled water, whose expiration date is a year after it is produced? Does it go bad after that first birthday? Does canned soda lose its fizz? There looked to be plenty of fizz last month when I systematically opened a dozen cans of soda and dumped the contents because the expiration date had passed. What about all those canned juices, soups, and fish that some of us stockpile for the epidemic of bird flu about which the media terrifies us from time to time? Does it go bad by the expiration date, even if it’s sitting unopened in a cool basement?
Some things we can eyeball, like lettuce. The printing on the bag says, “Best sold by such-and-such a date,” but does that mean we shouldn’t use it after that date? What if it looks, smells, and tastes perfectly good?
Tea bags have an expiration date. Same with oatmeal. And olive oil. And toothpaste. Even my cat’s food has an expiration date, and it is dry, hard food.
Are expiration dates nothing more than scare tactics to ensure new sales? Or is there a very practical and important purpose for them?
I’d love some feedback on this. Any of you work for drug companies and want to give it a try?
