What is the best possible means of avoiding bacterial contamination

Proper hand washing is one of the best ways to prevent bacterial infections. Although hand washing is simple and effective, it is often overlooked. Other good methods of preventing infection include covering your mouth and nose when you sneeze or cough, avoiding touching your eyes, nose or mouth, cleaning and disinfecting counters and other kitchen surfaces, cooking foods to proper temperatures, refrigerating foods promptly, following doctor's orders regarding immunizations, using antibiotics appropriately, practicing good hygiene around pets, and avoiding contact with wild animals.
