Can water expire? The truth behind water expiration dates


Most people don’t give much thought to the expiration date on their water. They assume that if there is an expiration date, it must mean that after that date, the water will become unsafe to drink.

Can water expire?




But what does expiration really really mean? Does it mean the water becomes unhealthy after some arbitrary number of days or weeks? As long as the water looks and smells okay, can you still safely drink it? Is there any expiration date on bottled water or just tap water? What happens to your body if you drink expired water? Do they really expire, or are they actually good until infinity and beyond?


How do companies decide to put an expiration date on bottles of water?


All companies have a legal responsibility to ensure that their products are safe for consumption. In order to do so, many companies include an expiration date on their products; if it is not included, they may still legally be held liable for expired foods and drinks sold to consumers. 


If a company does decide to put an expiration date on bottles of water, it is usually related to quality changes in taste and/or clarity rather than safety concerns. Water should remain fresh as long as it is not contaminated with bacteria or other toxins. When bottled water sits around too long, the plastic bottle can absorb the gases emitted by its contents (either air or liquid). When you open a bottle of this water, the gas creates bubbles which change the look and smell of the beverage.


Are there standards for how long bottled water can last?

It depends. There are no federal standards for the shelf life of bottled water, but some states have set laws and regulations that dictate how long a bottle of bottled water can be on a store shelf before it has to be pulled off (usually due to bacterial contamination). 


Most of these state-level requirements are around five years or less, which is pretty rare in terms of consumer goods. In most cases, this date does not mean the product will go bad or anything like that; instead, it means the product needs to be pulled from shelves because the producer cannot guarantee its safety and quality beyond this date. But don't worry - there's plenty of water left! 


It’s also important to note that even if you find a bottle with an out-of-date label, as long as the seal isn’t broken and the container looks clean and unopened, there’s still no reason to believe it won’t be safe.


How do you know when your bottled water goes bad?


Many people, when trying to determine if their bottled water has gone bad, will check to see if there is a visible change in taste or odor or if they just look at their bottles and decide it doesn’t look right. The problem with those methods is they’re not accurate and can end up costing you. So what are the more accurate ways of determining if your bottled water is still good? First, feel the bottle. 


If it feels like plastic, then the bottle isn't going bad anytime soon (usually). Second, twist off the cap and check for any cracks on the inside of the lid. If there are no cracks then your bottled water is probably safe to drink! Third, try unscrewing the cap and looking inside at where the lid screws onto the bottle. Is there mold around any of these areas?


Is it safe to drink expired bottled water?


Technically, yes—it’s safe to drink expired bottled water; however, it’s not necessarily good to drink expired bottled water. In general, if the date on a bottle of water is less than six months past the manufacture date (usually found on the bottom of the bottle), then it's probably safe to drink. But once that time passes, there's no guarantee as far as safety goes. If you're going to consume expired bottled water, you should boil it first for one minute and let it cool before drinking.


Do plastic bottles have an expiration date?


Some plastic bottles contain a date stamped on them as a safety measure to alert consumers of how long they will stay safe for consumption after production. However, that date typically does not indicate when the contents become unsafe for drinking; it simply alerts consumers to throw away any leftover fluids after an arbitrary length of time—usually a year or two—because they may have been exposed to light and oxygen, which can degrade some kinds of plastics over time. 


As per the FDA guidelines, bottled water is exempt from labeling with expiration dates because it’s in contact with atmospheric air at all times, which also degrades some plastics over time. Bottled water containers are designed to be sealed so you don’t need to worry about bacteria growing inside of your drink because there is no way for oxygen or light to penetrate through the container wall.


What happens if you drink expired bottled water?


Bottled water has an expiration date, but you shouldn’t drink it if it’s expired. Find out why and how long it is good after being opened. Drinking expired bottled water can be harmful to your health in some cases, so learn what you should do with an old bottle of drinking water.


 First, determine if the expiry date on the bottle is still valid by checking for a specific best before or use by the label. If there isn't one on the container or if it's been longer than six months since you last drank from the container, then don't drink it! There's no point in risking your health just because of a weird smell or taste. After all, water doesn't have an expiration date like food does. It won't spoil or turn into something else like milk will. 


You can even leave it outside in the sun without any issues as long as it doesn't get too hot (hotter than 50°C/122°F). And even if your favorite brand expires at that time, you'll still be able to purchase generic brands that are safe to drink.
