Reusable bottles can accumulate bacteria due to their constant use and the humid environment they provide, which encourages microbial growth. Frequent contact with the mouth and hands also contributes to the transfer of germs. If not cleaned regularly, these bacteria can proliferate, affecting the user’s health.
The growing popularity of reusable bottles As an ecological alternative to single-use ones, it promoted research into the health risks that may be associated with their continuous use. A recent study by water treatment experts at the Water Quality Association from the USA, revealed that this type of bottles can harbor different pathogens, some of which represent serious threats to health.
Among the main findings, two types of bacteria stand out: bacilli and the gram negative bacteria. Gram-negative bacteria, such as Escherichia coli and the Klebsiellaare known to trigger serious infections, including pneumonia. In addition, certain types of bacilli can cause gastrointestinal problems, generating symptoms such as nausea, vomiting and diarrhea.
Escherichia coli, a gram-negative bacteria, is often found in contaminated environments and can cause serious infections if ingested through poorly sanitized containers, such as reusable bottles.
Added to these pathogens are other microorganisms such as Staphylococcus aureuswhich can live in people’s nasal passages and skin, and Pseudomonascapable of resisting various treatments. They have also been detected fungusand in case of storing liquids rich in proteins such as milk or broth, the bottles can even promote the growth of Salmonella due to its high nutritional content for bacteria.
To ensure that a reusable bottle is always in optimal condition, experts advise washing it every day using hot water y detergent. This daily cleaning routine removes potential beverage residue and helps keep the bottle free of odors and flavors that can build up over time. In addition, it guarantees deeper cleaning on internal surfaces, including hard-to-reach areas such as the cap and rim of the bottle. By adopting this simple habit, you prolong the life of the container, and also ensure a fresh and pleasant hydration experience with each use.

To maintain a reusable bottle in optimal conditions and safe for daily use, it is important to follow certain recommendations when maintaining hygiene. The engineer Martin Piñadirector of the Food Engineering degree at UADE, explained to Infobae that the type of bottle material is a key factor. Bottles made to be reused are usually made of plastic, glass or stainless steel, the latter being the most recommended due to its smooth surface, which makes cleaning easier and reduces the accumulation of waste.
As for washing, it is essential to do it once a day or after each use, since the risk of accumulation of microorganisms increases the longer it remains uncleaned. To do it correctly, Piña advises using hot water and detergent, and sometimes a little alcohol for additional disinfection. It also suggests the use of special brushes or sponges, ideal for reaching all surfaces of the bottle. An effective technique is to fill it with warm water and detergent, shake it well, and rinse it completely before refilling.

Finally, Piña emphasizes the importance of using bottles as items of personal useThat is, avoid sharing them and always fill them with quality drinking water. With these basic care, it is possible to extend the useful life of the bottle and keep it in safe conditions for use.
