Researchers found that two nucleoside compounds (ddA and FdCyd) can effectively kill harmful bacteria like Vibrio and Salmonella that form slimy biofilms on seafood and food preparation surfaces. These compounds work by damaging bacterial cell membranes and preventing bacteria from communicating with each other. When combined with a food additive already used in the meat industry, these nucleosides become even more effective at much lower doses, potentially making food safer while reducing residual chemical effects.
