Environmental monitoring of Listeria spp. and Listeria monocytogenes in frozen food manufacturing

A study in the J. Food Protection (January 2020) from the University of Georgia surveyed frozen food manufacturing facilities on their practices of monitoring the environment for Listeria and Listeria monocytogenes. Food processors face serious challenges to eliminate Listeria monocytogenes contamination from their environment. A survey tool was created to obtain information on environmental monitoring programs within the frozen food industry. The survey showed that facilities are more likely to test for Listeria spp. in environmental monitoring zones 2 to 4 (nonfood contact areas) with emphasis on floors, walls, and drains. A few facilities incorporated active raw material and finished product testing for Listeria. The researchers concluded that the industry recognizes that environmental monitoring is a key component of a comprehensive food safety plan. @ https://meridian.allenpress.com/jfp/article-abstract/83/1/172/425639/Evaluating-Environmental-Monitoring-Protocols-for?redirectedFrom=fulltext
