We love reusable water bottles for being environmentally friendly and their cost effectiveness. According to 2016 data, reusable bottles can have as many or more organisms as some of our most germ-infected items (think tooth brush holders, toilet seats and pet toys). Researchers collected 12 swabs of three different types of water bottles that hadn’t been washed for a week. They analyzed the swabs in a lab and found some of the bottles had approximately 300,000 colony-forming units of bacteria per square centimeter. A used pet toy, on average, has less than 3,000 units per square centimeter, according to the analysis.
