Listeria biofilm under attack from new disinfectant

This disinfectant can remove biofilms containing Listeria monocytognes from meat processing facilities

Listeria monocytogenes can thrive on the work surfaces of meat processing plants because it can withstand low temperatures and can even grow in or on refrigerated foods. The hardy pathogen is also a serious public health problem.
According to the US Department of Agriculture (USDA), L. monocytogenes causes serious illness in 2,500 people a year, resulting in 500 deaths.
“Results showed that the formulation was 100 percent effective, providing total kill and more than 90 percent biofilm removal,” said Arnold. “Test evaluations also resulted in instructions for use that will meet USDA ‘zero tolerance’ regulations for L. monocytogenes.”
Summing up the results, Arnold said: “This disinfectant is more effective than currently used disinfectants in reducing L. monocytogenes biofilm growth, thus minimizing the risk of pathogenic contamination.”
Biofilms have more opportunity than ever before to develop in meat and poultry, according to ARS. Despite increased concern over safety, modern production techniques and preservatives have resulted in additional contamination risks.
“Today’s longer production runs provide more opportunity for biofilms to establish themselves, and today’s longer shelf life adds to the risk of biological contamination,” Arnold.
