Research – Assessment of the risk of botulism from chilled, vacuum/modified atmosphere packed fresh beef, lamb and pork held at 3 °C–8 °C

Science Direct

 

The safety of current UK industry practice (including shelf-life) for chilled, vacuum/modified atmosphere-packed fresh red meat (beef, lamb and pork) held at 3°C–8°C has been evaluated with respect to non-proteolytic Clostridium botulinum. UK industry typically applies a retail pack shelf-life at 3°C–8°C to 13 days for fresh red meat, with a maximum of 23 days for beef, 27 days for lamb, and 18 days for pork. An exposure assessment established that current commercial practice for fresh red meat provided strong protection with more than 1010 person servings marketed in the UK without association with foodborne botulism. A challenge test demonstrated that spores of non-proteolytic C. botulinum inoculated on chilled vacuum-packed fresh red meat did not lead to detectable neurotoxin at day 50 for beef, day 35 for lamb, or day 25 for pork (i.e. <40 pg type B toxin and type E toxin g−1 of meat). The products were visually spoiled many days before these end points. The exposure assessment and challenge test demonstrated the safety of current UK industry practices for the shelf-life of fresh, vacuum-packed beef, lamb and pork held at 3°C–8°C with respect to C. botulinum, and that botulinum neurotoxin was not detected within their organoleptic shelf-life.

USA – California firm ordered to stop Norovirus claims

BARF BLOG

CBS Los Angeles reports a federal court ordered a Lake Forest company to stop distributing hand sanitizer products it touts as being able to fight specific diseases.

Innovative BioDefense Inc. of Lake Forest was ordered Monday to stop distributing its Zylast hand sanitizer products until it obtains FDA approval or removes removes disease-specific claims from its product labeling, according to the U.S. Department of Justice.

Cook Islands – Teacher on Life Support – Listeriosis

CIN

Health authorities are investigating the country’s first listeria infection in more than 10 years.

A young Rarotonga primary teacher has been evacuated to hospital in Auckland, where she is critically ill with listeria.

Apii Te Uki Ou teacher Grace Archer was flown to Auckland on Air New Zealand flight 945 last Friday, after the “acute deterioration” of her health. Her partner, fellow teacher Theo Warrick, was put on an emergency flight on Sunday night, to join her.

Dumplings all seven grades do not meet the requirements of the technical regulations of the Customs Union “On safety of meat and meat products”, said Roskoshestvo. In particular, all goods specialists found dangerous to the health of consumers of Escherichia coli and products of the same brand has revealed yet and Salmonella.

in addition to the presence in the products of dangerous bacteria, it has also been observed discrepancy between the labeling information. So, dumplings, two brands were significantly lower in protein.

Research – Antibacterial activity and mechanism of Litsea cubeba essential oil against food contamination by Escherichia coli and Salmonella enterica

Wiley Online

Litsea cubeba essential oil (LC‐EO) has been reported as antibacterial agents, but there are few studies about its possible antibacterial mechanism. The antibacterial activities and the underlying mechanisms of LC‐EO against Escherichia coli O157: H7 and Salmonella enterica were investigated. The results showed that the LC‐EO was more effective against gram‐negative bacteria. The inhibition zone for E. coli O157: H7 and S. enterica were 3.1 ± 0.8 and 4.5 ± 0.6 mm, respectively. The minimum inhibitory concentration of LC‐EO against both bacteria was 0.9 μg/ml, while the minimum bactericidal concentrations were 4.5 and 9 μg/ml. Gas chromatography–mass spectrometry analysis confirmed that citral (86.8%) was the main component of LC‐EO. The results of a time–kill analysis illustrated that treatment with LC‐EO led to a rapid decrease in viable bacterial cell number. The release of electrolytes and nucleic acids from the bacterial cells increased with the dose of LC‐EO. Propidium iodide uptake revealed that LC‐EO caused cell membrane damage. Scanning electron and transmission electron microscopy showed that LC‐EO caused damage to the cell walls and membranes, resulting in cell deformation, atrophy, and large central voids. Thus, LC‐EO may provide the basis for the development of new natural food preservatives.

Research – Chicken study probes resistance to Campylobacter

Poultry World

Transplanting gut microbes from chickens that are relatively resistant to Campylobacter bacteria into chickens that are susceptible does not improve resistance, a study by The Roslin Institute at the University of Edinburgh has shown.

Campylobacter is a cause of food poisoning in people and is often found in chickens. In the UK alone, it is estimated that more than half a million people are infected with Campylobacter each year.
