An animal science specialist from California State University, Fresno is overseeing a study that could result in better public protection from dangerous meat-borne bacteria such as Salmonella, E. coli, Staphylococcus aureus and Streptococcus fecalis. Veterinarian Michael Thomas, also a professor of animal sciences and agricultural education, is overseeing tests to determine if a commercial skin- protecting lotion combined with a common antibacterial compound will help control or prevent the spread of unwanted bacteria in the food service, medical and other industries. Unreported cases are likely far greater. And while more stringent food service regulations, such as requirements to cook burger patties longer, have helped reduce danger to the public, they haven't eliminated them. Workers who handle contaminated meat before it is cooked can bring the organisms onto their fingers and hands, then pass them onto other uncooked foods such as lettuce and bread during food preparation.
Workers can use antibacterial soap to remove most of the bacteria from their hands.
However, repeated contact with uncooked meats and other materials makes it nearly impossible to prevent the spread of at least some unwanted organisms. And that is what raises the importance of Thomas' work. The new compound he is testing includes a commercial skin lotion used as a protectant against chemical exposure. The lotion provides an inert, polymer coating that lasts four hours, even through washings. Combined with that is a safe antibacterial agent.
