Research – Biofilms with Listeria pose persistent threat in food production

It doesn’t matter how big or influential a company is, bacteria and biofilms don’t discriminate between multinationals like Dole with its tens of thousands of employees and operations like Hudson Valley Farms, where 10 or fewer people work.

Both of those companies have had close encounters with Listeria, which on-going research is showing can be even tougher to kill than previously thought. When the microorganism has time to set up housekeeping in a biofilm in crevices on equipment or around drains and cracks in floors it is even more difficult to evict.
