Although environmentally friendly, the large bottles of shower gel and shampoo in hotels pose a high risk of bacterial contamination due to inadequate cleaning and refilling procedures.
Instead of providing mini-sets of high-end brands, many hotels are now switching to large ceramic or glass containers for shower gel and shampoo. This solution aims to protect the environment and optimize operating costs by refilling the containers when guests run out. However, this change is raising significant concerns about hygiene and safety for users.
Risk of bacterial contamination from shared containers.
Dr. Charles Gerba, a professor of virology at the University of Arizona (USA), advises travelers to be cautious with these items. According to him, large containers with open lids can allow bacteria to enter from the external environment or from previous guests. Even if the container is locked and only housekeeping staff can open it, hygiene cannot be absolutely guaranteed.
Dr. Gerba's research indicates that bacteria tend to proliferate rapidly in refillable containers. Specifically, rod-shaped bacteria (coliforms) – the causative agents of intestinal diseases and diarrhea – are often found in large numbers in these containers. While adding new solution may temporarily reduce the bacterial count with antibacterial components, they quickly grow back afterward.
Gaps in hotel hygiene procedures
One of the main reasons these containers become breeding grounds for bacteria is due to inadequate cleaning procedures. In most cases, cleaning staff only wipe down the outside surface of the container when cleaning the bathroom. Completely emptying the old solution and thoroughly cleaning the inside of the container is rarely done between guests.
Furthermore, the trend of using refillable products is becoming a mandatory regulation in many places. In the US, California took the lead in banning single-use cleaning products in 2018. This was followed by Washington, and it is expected that by the end of 2024, all hotels with more than 50 rooms in the US will have to comply with regulations requiring the use of large-capacity containers to protect the environment.
Solutions to ensure the safety of tourists.
To maintain a sustainable lifestyle while protecting personal health, experts recommend that travelers prepare their own personal cosmetic containers when traveling . Bringing your own shower gel and shampoo allows users to have complete control over the quality of the products and the hygiene of the containers.
Furthermore, using personal toiletries provides peace of mind, eliminating worries about sharing hygiene products with strangers in a hotel environment. This is the best way to fully enjoy your trip safely.
