According to a CBS News Report, a new study finds that almost half of the meat sold in America's supermarkets is contaminated with drug-resistant staph bacteria.

To conduct this study, researchers bought beef, pork and chicken in super markets in five U.S. cities. 47% of the meat sampled contained drug resistant strains of Staphylococcus aureus.

It's important to not only cook all meat thoroughly, but to take caution in how you handle it.

Experts note that staph bacteria can be killed by thoroughly cooking meat, but improper handling and cross-contamination -- such as by reusing a cutting board or knife that has come in contact with the raw meat -- can still lead to infections.

The study was released in the April 15th edition of the medical journal "Clinical Infectious Diseases".
