Chemicals that keep drinking water flowing may also cause fouling
Many cities drinking water systems add softening agents to keep plumbing free of pipe-clogging mineral build-up. According to new research from the University of Illinois, these additives may amplify the risk of pathogen release into drinking water by weakening the grip that bacteria – like those responsible for Legionnaires’ disease – have on pipe interiors. Biofilms, which are similar to the films that grow on the glass of fish tanks, are present in almost all plumbing systems and anchor themselves to mineral scale build-ups in pipes. They are teeming with harmless microbial life and incidents of waterborne illness are rare. Read More
Many foods produced on an industrial scale include raw ingredients mixed together in enormous stainless-steel machines that can be difficult to clean. With repeated use, equipment surfaces get minute scratches and grooves, providing bacteria and biofilms the perfect place to hide. While surface scratches may appear small to the naked eye, they are like a canyon to bacteria, which are only a few micrometers in size. Surface-trapped food residue and bacteria then increase the risk of contamination from microorganisms such as Salmonella, ListeriaandE. coli. Read More
