Cosmetics can become unsafe for consumers if they’re contaminated with harmful microorganisms, such as certain bacteria and fungi. The FDA is looking closely at the microbiological safety of cosmetics.  

Companies and individuals who manufacture or distribute cosmetics are legally responsible for the safety of their products. This includes, for example, making sure cosmetics are free of harmful microorganisms.

 Some of the questions FDA microbiologists are exploring include:

• What’s the best way to test cosmetics for microbiological safety?
• What types of preservative systems are cosmetic companies using, and how effective are they?
• What kinds of microorganisms pose health risks in cosmetics?
• How are people exposed to microorganisms in cosmetics?
