3. Bacteria and basic hygiene breaches
Drinking water from a used plastic bottle is almost the same as licking a toilet seat, a dog’s toy, or even worse scientists say. The amount of bacteria in such bottles often exceeds safety limits. We create the perfect growth conditions ourselves by taking the bottle with dirty hands, not rinsing it thoroughly enough, and keeping warm water in it.
What to do then? Wash bottles regularly with warm soapy water, vinegar, or antibacterial mouthwash.
Even with washing the bottles thoroughly, we may still get food poisoning or even hepatitis A. Research showed that most bacteria live on bottle necks that you can’t wash well enough. Twist caps and sliding caps teem with germs that you swallow along with water. To be on the safe side, use a straw.
