Quick Answer
If boiled water is stored improperly, it can become re-contaminated, causing waterborne illnesses such as cholera, dysentery, or typhoid fever. Re-contamination can occur through contact with contaminated surfaces, poor sanitation, or inadequate storage containers. This can render the boiled water unsafe for consumption.
Contamination Risk Factors
Storing boiled water in an improperly closed container or a container with a narrow opening can allow bacteria, viruses, and protozoa to enter the water. This is especially true if the container is not kept away from human contact or other contaminated sources. For example, storing boiled water in a container with a lid that is not securely closed can allow airborne bacteria to land on the surface of the water.
Storage Container Considerations
When storing boiled water, it’s essential to use a clean, covered container with a wide mouth. The container should be made of a non-reactive material, such as stainless steel, glass, or BPA-free plastic. The container should be kept in a clean, dry area, away from direct sunlight and heat sources. It’s also crucial to store the container off the ground to prevent contact with contaminated surfaces or pests.
Best Practices for Safe Storage
To minimize the risk of re-contamination, it’s recommended to store boiled water in the refrigerator or a cooler. If a refrigerator or cooler is not available, the container should be stored in a shaded area, away from direct sunlight. The container should be kept tightly sealed and stored upright to prevent spills or leaks. Additionally, the boiled water should be consumed within 24 hours or frozen for longer-term storage.
