Is 20-year-old bottled water safe to drink? Generally, it’s not recommended to consume bottled water that is 20 years old. Over time, the quality and safety of the water can degrade due to factors like plastic leaching, microbial growth, and changes in taste.
What Happens to Bottled Water Over Time?
Does Bottled Water Expire?
While bottled water itself doesn’t "expire" in the way food does, it can become unsafe or unpleasant to drink over time. Most bottled water has a shelf life of about 2 years, primarily due to the packaging rather than the water itself. The plastic bottles can degrade, potentially leaching chemicals into the water.
How Does Plastic Affect Water Quality?
Plastic bottles are made from materials such as PET (polyethylene terephthalate), which can break down over time. This degradation can lead to the release of chemicals like antimony and bisphenol A (BPA), especially if bottles are exposed to heat or sunlight. These chemicals can affect the taste and safety of the water.
Can Microbial Growth Occur in Bottled Water?
Yes, microbial growth is possible, especially if the seal of the bottle is compromised. Over time, even a small breach can allow bacteria or mold to enter and grow, particularly if the bottles are stored in warm or humid conditions.
Is It Safe to Drink 20-Year-Old Bottled Water?
What Are the Risks of Drinking Old Bottled Water?
- Chemical Contamination: As mentioned, chemicals from the plastic can leach into the water.
- Microbial Contamination: Bacteria and mold can develop if the seal is broken.
- Taste and Odor Changes: Even if not harmful, the water may taste stale or have an off odor.
How to Determine If Bottled Water Is Safe?
- Check the Seal: Ensure the bottle’s seal is intact.
- Inspect the Bottle: Look for any signs of damage or discoloration.
- Smell and Taste: If it smells or tastes unusual, it’s best not to drink it.
Proper Storage of Bottled Water
How Should Bottled Water Be Stored?
- Cool, Dark Place: Store in a location away from sunlight and heat.
- Stable Temperature: Avoid areas with fluctuating temperatures, like garages or attics.
- Upright Position: Keep bottles upright to prevent leaks.
Why Is Proper Storage Important?
Proper storage helps maintain the quality and safety of bottled water by minimizing the risk of chemical leaching and microbial growth. It also helps preserve the taste and freshness of the water.
People Also Ask
Can Bottled Water Go Bad?
Bottled water doesn’t spoil like perishable items, but its quality can degrade over time. Factors such as exposure to heat and sunlight can accelerate this process, leading to potential safety concerns.
How Long Can You Store Bottled Water?
Ideally, bottled water should be consumed within 2 years of purchase. This timeframe helps ensure the water remains fresh and free from potential contaminants introduced by the packaging.
What Happens If You Drink Expired Bottled Water?
Drinking expired bottled water might expose you to chemicals leached from the plastic or microbial contaminants if the bottle’s seal is compromised. The taste and odor may also be unpleasant.
Is It Safe to Drink Bottled Water Left in a Hot Car?
Leaving bottled water in a hot car can cause the plastic to break down, releasing chemicals into the water. It’s best to avoid drinking water that’s been exposed to high temperatures for extended periods.
Conclusion
While water itself doesn’t expire, the packaging and storage conditions significantly impact its safety and quality over time. For optimal safety, it’s advisable to consume bottled water within its recommended shelf life and store it properly. If you’re unsure about the safety of old bottled water, it’s better to err on the side of caution and dispose of it.
