SafeTsource non-animal origin microbial products can be used in a wide variety of applications where the presence of animal-derived products are of concern. The SafeTsource product line includes microbial cultures, growth media and a cryoprotectant. They are applicable for quality control testing where products are manufactured using aseptic processing.

SafeTsource microorganisms are grown on vegetable-based media and freeze-dried without contacting animal-derived materials. All SafeTsource cultures originate from pre-1980 seed stocks, meaning they have been preserved at ATCC prior to 1980, the date mentioned in FDA guidance for reducing the risk of BSE.

SafeTsource microorganisms listed below with their associated ATCC number are currently available; other strains will be available soon.
