Cornell University researchers have identified five previously unknown strains of Listeria in United States soil. "This research increases the set of listeria species monitored in food production environments," said  Catharine R. Carlin, a doctoral student in food science. "Expanding the knowledge base to understand the diversity of listeria will save the commercial food world confusion and errors, as well as prevent contamination, explain false positives and thwart foodborne outbreaks."

Continuous quality improvement is the ongoing process of raising the performance of an organization (and thereby improving products, services, people, and systems) to provide added value for consumers and a better working environment for employees. 

More and more, consumer become concerned about food safety. Incidents of foodborne illness and recalls are seemingly ubiquitous as supply chains globalize and controls struggle to keep up. Manufacturers must make efforts to address these vulnerabilities in their processes. One way to do so is to adopt a widely recognized food safety and quality standard, like FSSC 22000.
