Pharmaceutical and medical products undergo bioburden testing to prove they do not contain harmful bacteria or contaminants.

Bioburden testing, or microbial limit testing, evaluates and establishes the amount of microorganisms or bacteria present in a substance before it has been sterilised. Bioburden testing acts as a quality control measure to expose any contaminants, so that scientists and manufacturers can ensure these contaminants are removed and are not detectable in the end product.
