What is Microbial Testing?

With applications to our daily lives, microbial testing is used to detect, isolate, identify, and enumerate potentially harmful pathogens in everyday items including food, beverages, and drinking water. 

Why is Microbial Testing Important?

We live in a world surrounded by microbes, thus microbiology has many important applications in the medical, environmental, food, agriculture, pharmaceutical, cosmetic, and many other industries. Of the microbes that exist in our ecosystem, some are beneficial and perform essential functions such as cycling nutrients, while others can be detrimental to human health and cause infection or disease. Therefore, it is critical to determine the possible presence of harmful microbes in products before they are consumed. 

Symbio Laboratories conducts high-quality microbiological testing with rigorous standards set by regulatory agencies such as the Environmental Protection Agency (EPA), current Good Manufacturing Practices (cGMP), The California State Water Boards, The Association of Official Agricultural Chemists (AOAC), and The Transnational Institute (TNI).
