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.

UK: New diagnostic tests could hamper tracking of foodborne illness

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.

NL: Around the world in 1,475 Salmonella geo-serotypes

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.

AU: Reports on the use of nanotechnology in food additives and packaging

Food Standards Australia New Zealand: In 2015 an expert toxicologist prepared two reports for FSANZ on the potential use of nanotechnologies in existing food additives and food packaging. The reports were then peer reviewed by an expert pharmacologist and toxicologist to evaluate whether the conclusions for each of the reports were supported by the weight of evidence in scientific literature. The peer review agreed with the overall conclusions of the reports.

AU: Cassava: the staple crop that can kill you

Food Processing: Easy to cultivate and drought-tolerant, the cassava plant is eaten by a billion people around the world every day. But its popularity is also its weakness, as attacks by pests and diseases have a potentially huge impact on food security. It’s also the only staple crop that can kill you or cause chronic neurological disease if it’s not processed, potentially producing fatal levels of cyanide when drought-stressed.

US: Report: genetically modified crops pose no health risks

Food Safety Magazine: The National Academies of Sciences, Engineering, and Medicine (NASEM) has discovered that, after extensive research, there is no distinct difference between food crops that are genetically modified (GM) and those that are conventionally grown. Their research also uncovered no clear difference in risks to human health or the environment between the two types of crops.

US: Study looks at lettuce grown near livestock

The Packer: Lettuce grown too close to livestock production areas can be at greater risk of pathogen contamination. That’s the conclusion of a recent study by scientists at New York’s Clarkson University, “Bioaerosol Deposition to Food Crops near Manure Application: Quantitative Microbial Risk Assessment.”
