Research – Dairy Products are Most Common Source of Listeria Outbreaks

Food Poisoning Bulletin

Dairy products were the most common source of Listeria outbreaks that occurred between 1998 and 2012, according to a new federal study by the Food Safety Analytics Collaboration of the Centers for Disease Control and Prevention (CDC), the U.S. Food and Drug Administration (FDA) and U.S. Department of Agriculture (USDA). The study was conducted to provide information that can be used to develop better food poisoning prevention measures.

Of the 952 outbreaks attributed to one pathogen during the 14-year study period, 24 were Listeria outbreaks. Dairy products were the source of half them. Turkey was the source of four; pork and sprouts each caused two; and beef, chicken, fruit and row crop vegetables each caused one. The fruit outbreak, the cantaloupe Listeria outbreak of 2011, sickened 147 people and killed 35.

Research – Listeria’s Resistance to Disinfectants

Listeria poses a significant risk to human health. The main transmission route involves meat and dairy products, so it is important to treat dairies and food-processing plants regularly with disinfectants to kill bacteria. Unfortunately, listeria is developing resistance to the compounds that are most frequently used. Recent work in the group of Stephan Schmitz-Esser at the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) has uncovered the mechanism for listeria’s resistance to one such agent, benzalkonium chloride. The findings have been published in the online journal Plos One.
