Microorganisms are all around us and can come in contact with the food we eat and the consumer products we use. While most are harmless, some microorganisms can be dangerous to public health. UL’s microbiological testing services can evaluate your food and consumer products to determine if potentially harmful pathogens are found in your products.

Benefits of Microbiological Testing

Microbiological testing is a key component of any successful quality program. Our analyses can identify contaminations in your merchandise, determine shelf life of your product before degeneration, evaluate various types of environment for storage compatibility, and more.

For food and beverage products, microbiological testing can help detect toxic pathogens like Listeria, Salmonella, E. coli, and other microorganisms that cause food to spoil like yeast or mold. A microbiological testing program can unearth hazardous microbes before they have a chance to reach customers and potentially cause illnesses and damage to a brand’s reputation.

Food contact


Pet products


Juvenile products


Personal care and beauty


Textile, apparel and footwear


Paper products and consumables


Premiums and promotional products


Packaging materials
