Food Safety News: Research, published Monday in the journal Nature, reports DNA analysis has unmasked Salmonella enterica bacteria as the cause of a 16th century epidemic that affected large parts of Mexico and wiped out an estimated 800,000 people in the Aztec Empire.

Fresh Plaza: [Cold plasma] has the capacity to kill microbial pathogens on the surface of fresh produce and nuts without leaving any chemical residues. Other spoilage-causing moulds can also be suppressed, offering a longer shelf-life and reduced food waste.
UC Davis Postharvest Technology Center: As a global resource, the UC Postharvest Technology Center website is visited over 3 million times a year and contains more than 660 pages and 750 documents with postharvest information and related resources.
The Packer: Consumers are much more concerned about raw chicken and raw beef being contaminated than raw fruits and vegetables, according to a new food safety survey.

Scoop: A new partnership involving nine New Zealand research organisations has been awarded $1.25 million in funding from the Ministry of Business, Innovation and Employment. The New Zealand-China Food Protection Network (NZ-CFPN) will enhance communication between research scientists, government organisations and industries here and in China
US: Metrics proposed to prevent the harvest of leafy green crops exposed to floodwater contaminated with Escherichia coli
Allied and Environmental Microbiology: In this study, the suitability of the LGMA metrics for farms in the Mid-Atlantic region of the United States was evaluated. The upper end of a spinach bed (in Beltsville, MD) established on a −5% grade was flooded with water containing 6 log CFU/ml Escherichia coli to model a worst-case scenario of bacterial movement through soil. While E. coli was quickly detected at the 9-m distance within 1 day in the spring trial and within 3 days in the fall trial, no E. coli was detected on plants outside the flood zone after 14 days.
Food Safety Watch: So-called culture-independent diagnostic tests (CIDTs) help doctors diagnose foodborne infections in a matter of hours because they do not depend on traditional bacterial culture techniques, which often take several days to complete. Unfortunately, the absence of a bacterial culture makes it difficult to obtain detailed information from the bacteria responsible for the infection, such as genetic fingerprint and genome sequencing data.
Emerging Infectious Diseases: It’s easy to remember Salmonella serotypes names, isn’t it? Surely, this is because the naming system of Salmonella serotypes is by far the most scientist friendly. Traditionally, most Salmonella serotypes have been named after geographic locations. We decided to explore the geographic locations to which Salmonella serotypes refer and describe some unexpected twists in the naming scheme. We found that 93% (n = 1,475) of the 1,585 serotypes could be categorized as geo-serotypes; that is, the name refers to a geographic location.
