Germ Studies

Due to common misconceptions about where the highest concentration of germs may be found in homes, schools and other environments, NSF International has undertaken several studies to help identify where germs may be hiding.

Germs are a reality of everyday life and despite our best efforts, there is no way to avoid them completely. While not all bacteria are harmful, some (such as Staphylococcus aureus and Salmonella) can pose a health risk to humans, and they’re more frequently found on common household and school items than one would think.

NSF has conducted several surveys to help identify where germs lurk in our environment. Learn more about these studies and steps you can take to reduce your exposure to germs.
