BioScience Laboratories uses the approved ASTM E2946-13 method as well as other methods to conduct these studies. Subjects contaminate hands with E. coli incorporated into a medium or heavy organic soil (beef broth or hamburger, respectively), which then is distributed over all surfaces of the hands and fingers to result in a minimum baseline recovery population of ≥107 colony forming units (CFU)/hand. Test material effectiveness is measured by comparing the number of challenge bacteria recovered from contaminated hands after a single application of the test material to the number recovered from contaminated hands not exposed to the test material.
BSLI has designed custom studies to test these kinds of products, as well as to evaluate transmissibility of bacteria from contaminated foodstuffs to hands and back to foodstuffs, and whether use of gloves made of various materials for food-handling is protective of the consumer or actually adds to the public health risk of failure to wash hands that gloving originally was intended to solve. Some of BSLI’s most inventive study design work has been directed at testing the effectiveness of antimicrobial processes for controlling the numerous human factors that contribute to incidence of food-borne diseases.
Our start-to-finish solution for clinical trials begins with understanding our client’s end goals for the study and aiding them in the study design. Throughout the project we remain in on-going contact with our sponsors to ensure that the project is managed with the best interest of the client in mind.…
