A study by Universidad Manuela Beltrán in Colombia found that all 32 helmets analyzed from transportation platforms contained some type of microorganism, including aerobic bacteria, coliforms, fungi, and yeast. The research highlighted the presence of E. coli, which is associated with fecal contamination, though researchers clarified that this does not necessarily mean users would become ill. The study recommends measures such as using disposable covers, ensuring the helmet lining is dry, avoiding sharing personal items like scarves, and washing hands after rides. It also calls for drivers to regularly clean and disinfect helmets to reduce microbial buildup.
