Research -Bacillus cereus-induced food-borne outbreaks in France, 2007 to 2014: epidemiology and genetic characterisation


The aim of this study was to identify and characterise Bacillus cereus from a unique national collection of 564 strains associated with 140 strong-evidence food-borne outbreaks (FBOs) occurring in France during 2007 to 2014. Starchy food and vegetables were the most frequent food vehicles identified; 747 of 911 human cases occurred in institutional catering contexts. Incubation period was significantly shorter for emetic strains compared with diarrhoeal strains A sub-panel of 149 strains strictly associated to 74 FBOs and selected on Coliphage M13-PCR pattern, was studied for detection of the genes encoding cereulide, diarrhoeic toxins (Nhe, Hbl, CytK1 and CytK2) and haemolysin (HlyII), as well as panC phylogenetic classification. This clustered the strains into 12 genetic signatures (GSs) highlighting the virulence potential of each strain. GS1 (nhe genes only) and GS2 (nhe, hbl and cytK2), were the most prevalent GS and may have a large impact on human health as they were present in 28% and 31% of FBOs, respectively. Our study provides a convenient molecular scheme for characterisation of B. cereus strains responsible for FBOs in order to improve the monitoring and investigation of B. cereus-induced FBOs, assess emerging clusters and diversity of strains.

USA -Bull calves likely source of drug resistant Salmonella outbreak

Food Safety News

Twenty-one people infected with an outbreak strain of multi-drug resistant Salmonella Heidelberg have been reported from eight states, the federal Centers for Disease Control and Prevention (CDC) reported Monday. The illnesses may be associated with dairy bull calves or other cattle.

CDC is investigating along with Wisconsin health, agriculture, and laboratory agencies, several other states, and the U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA-APHIS).

Of the eight impacted states, Wisconsin has the most cases with 12.   Minnesota and South Dakota have two each, and California, Iowa, Idaho, Missouri and Oklahoma have each reported one.

Described as a “purple blow torch” by food safety scientists, cold plasma treatment can kill 99.9 percent of norovirus on blueberries without damaging the delicate fruit, giving a food safety boost to the so-called superfood.

Brendan Niemira, a microbiologist at the U.S. Department of Agriculture’s Eastern Regional Research Center in Wyndmoor, PA, and a team of scientists already demonstrated that cold plasma (CP) can kill pathogens such as Salmonella and E. coli on blueberries.

Europe -350 sick in outbreak traced to Polish eggs; trade regs eyed – Salmonella

Food Safety News EGGS

The number of people infected by Salmonella traced to a Polish egg farm has topped 350 with 10 countries now reporting confirmed and probable cases.

The victim count has increased substantially since October when the European Food Safety Authority reported 260 illnesses across seven countries between May 1 and Oct. 12 this year.

Wozniak Poultry Farms in Poland has been identified as the egg producer. Recalls were initiated across Europe and in Hong Kong and the outbreak has stirred questions about trade regulations.
