Causes

By Mayo Clinic staff

Many people carry staph bacteria and never develop staph infections. If you have a staph infection, there's a good chance that it stemmed from bacteria you've been carrying around for some time.

These bacteria also can be transmitted from person to person. Because staph bacteria are so hardy, they can live on inanimate objects like pillowcases or towels long enough to transfer to the next person who touches them.

Staph bacteria are able to survive:

  • Drying
  • Extremes of temperature
  • High levels of salt

Even cooking won't kill the toxins produced by staph bacteria, which is why they can cause food-borne illness.
