When you’ve ever taken a sip from the glass of day-old water, you’ve probably realized that it tastes a little bit different. You might also have seen an expiration date printed in the plastic packaging. So does that imply that water goes bad?
Does tap water go bad?
Tap water could be kept and consumed for as much as six months with low risk of adverse side-effects so long as it has been kept properly.
Then again, tap water which has been carbonated could become flat since the gas gradually goes out from the liquid, causing changes on the flavor.
Regular water also could create a stale taste as time passes, which can be brought on by carbon dioxide in the air combining with the water and turning it into a bit more acidic.
Although these kinds of water could have an off taste, they’re still often considered safe to drink for as much as six months.
When preparing tap water for storage, make use of sanitized and cleaned food-grade water bottles. Label these with the filling date and tag that they hold drinking water. Keep the containers within a cool, dry, and dark area for about six months.
Bottled Water Can Expire
Although water alone doesn’t expire, bottled water usually includes an expiration date. In accordance with the International Bottled Water Association, the Food and Drug Administration (FDA) has identified that “there isn’t any limit to the shelf life of bottled water,” and also the FDA doesn’t mandate bottled water companies to add an expiration date.
The Centers for Disease Control and Prevention (CDC) likewise considered that in the event of an emergency, bottled water is definitely the safest kind of water to have available as it could be kept for such a long time, however it needs to be stored properly. The CDC suggests keeping water within a cool, dark place and not damaging the seals on bottled water till you’re required to drink it.
The CDC likewise mentioned that it’s crucial to stay bottled water away from toxins such as pesticide sprays and gasoline, since the plastic is permeable. Additionally , they suggest keeping it away from direct sunlight, mainly because a few plastics could discharge the chemical bisphenol A (BPA), that has been tentatively associated with numerous health problems such as heart ailment and cancer.
Why Does Bottled Water Have an Expiration Date?
During 1987, New Jersey had become the first and only U.S. state to pass a law demanding that all of the food items – such as bottled water – have an expiration date of two years or less coming from the date of manufacture.
During the time this law was approved, stamping an expiration date had become an industry standard for bottled water companies all around the world.
Even so, this law was later on revised, and no more present legislation in the United States demands companies to print an expiration date in bottled water.
Even now, it’s basically not recommended to drink water coming from plastic bottles that’s way way past its expiration date.
