A treatment to infuse hardened metal surfaces with naturally occurring antimicrobial peptides has been developed by researchers at Purdue University.
In other words, the Purdue research team’s technology can create hard metal surfaces that kill bacteria trying to attach to it.
David Bahr, team leader and professor of materials engineering at Purdue, said this technology applies primarily to food processing and cutting surfaces, which can be especially vulnerable to bacteria growth because of the materials and surface designs.
This technology can reduce the risk of cross-contamination. Cross-contamination is the transfer of harmful bacteria to food from other foods, cutting boards, utensils, etc. This is especially true when handling raw meat, poultry, and seafood, as placing them on the same hard surface as already cooked or ready-to-eat foods and fresh produce can spread harmful bacteria.
