USA – Tuna Link in Multi-State Salmonella Sushi Outbreak

Food Poisoning Journal

As of June 4, 2015, a total of 53 people infected with the outbreak strain of Salmonella Paratyphi B variant L(+) tartrate(+) have been reported from nine states. Ten ill people have been hospitalized. No deaths have been reported. Most of the ill people have been reported from the southwestern United States, or reported travel to this part of the country in the week before they became ill. The number of ill people reported from each state is as follows: Arizona (10), California (31), Illinois (1), Mississippi (1), New Mexico (6), South Dakota (1), Virginia (1), Washington (1), and Wisconsin (1).

UK – FSA Annual Report 2014 – Incident Notifications

FSA food_standards_agency_logo

This report acts as a public record of incident levels for reference purposes. It presents numbers and types of incident notifications to the Food Standards Agency (FSA) during 2014 that had the potential to impact on the safety of food or feed.

Incidents are defined broadly, and differ widely in types, causes, severity and the route of reporting. The report includes breakdowns of the number of reported food and feed incidents by incident categories, notifier, country of origin, and food commodity type.

The FSA will investigate incidents to determine whether there are any food safety implications.

Where appropriate, it will then take action to safeguard the public. The FSA’s Incident Database records the official audit trail of the investigations. It is the main source of the figures in the report.

The FSA also arranges the issue of food alerts to local authorities, other government departments, trade organisations, and Rapid Alert System for Food and Feed (RASFF) notifications to the European Commission. Furthermore, as part of its incident prevention strategy, the FSA monitors food and feed safety patterns in England, Wales and Northern Ireland and promotes awareness, good practice and information sharing.

Executive summary

In 2014, the Food Standards Agency was notified of and investigated 1,645 food, feed and environmental contamination incidents in the UK. The overall number of incidents was similar to those seen in recent years. However, in most categories, the numbers of incidents differ considerably from year to year.

The four largest contributors to the total number of recorded incidents in 2014 were:

• microbiological contamination (24%)

• veterinary medicines (13%)

• environmental contamination (12%)

• natural chemical contamination (9%)

Research – How Salmonella Synchronises its Invasion Plan

EurekAlert

A new study from the Institute of Food Research has uncovered a mechanism by which Salmonella bacteria organise the expression of genes required for infection.

Salmonella bacteria are the leading cause of food borne illness in the EU. Part of what makes them so successful is their ability to invade our bodies, overcoming our natural defences. Understanding how they do this could lead to new ways of preventing their invasion.

Most Salmonella infections result in gastroenteritis, when the bacteria invade the epithelial cells lining our gut. However, under certain conditions, Salmonella can subsequently cause a potentially lethal systemic typhoidal infection when they invade the underlying immune cells. The invasion of epithelial cells and immune cells are controlled by two separate gene clusters called Salmonella Pathogenicity Islands 1 and 2 (SPI1, SPI2) respectively.

UK – Salmonella Outbreak 2014 Report – Heartlands Hospital: Salmonella Outbreak Leads to Death

BBC News

A report has found a salmonella outbreak at a Birmingham hospital directly caused the death of a patient.

The outbreak at Heartlands Hospital in Bordesley Green, between 25 May and 18 June 2014, saw 32 staff and patients infected.

Five of those patients, who were seriously ill, later died, but salmonella was not directly responsible, the report said.

The outbreak was traced to contaminated eggs produced in Bavaria, Germany.

Prof Eric Bolton’s report found inadequately equipped wards, unmonitored food preparation, and poor cleaning helped it spread.

Research – Comparison of Oxygen- and Nitrogen-Enriched Atmospheres on the Growth of Listeria Monocytogenes Inoculated on Poultry Breast Fillets

Wiley Online Library

The growth behavior of Listeria monocytogenes in the presence of typical spoilage microorganisms on poultry breast fillets (Pseudomonas spp., Brochothrix thermosphacta, Enterobacteriaceae, Lactobacillus spp., total viable count) was investigated. The aim of the study was to compare the growth of L. monocytogenes under oxygen- and nitrogen-enriched atmospheres and to figure out possible interactions between L. monocytogenes and typical spoilage microorganisms on skinless poultry breast fillets. Therefore, the natural meat surface was inoculated with L. monocytogenes and packed under two commonly used gas atmospheres (70% O2/30% CO2 and 70% N2/30% CO2). The atmosphere was monitored over the storage period and typical sensory attributes (color, odor, texture, drip loss and general appearance) were evaluated. The results show that the storage under 70% N2/30% CO2 favored the growth of L. monocytogenes in comparison with the 70% O2/30% CO2. Under nitrogen, L. monocytogenes reached a maximal bacterial count of 5.7 (log10 cfu/g) after approximately 500 h of storage, but no specific microorganism could be identified responsible for the favored growth. The growth of L. monocytogenes was suppressed in the oxygen-enriched atmosphere, whereas B. thermosphacta dominated the spoilage flora. The results indicate that the combination of high oxygen with carbon dioxide and possible interactions with the spoilage background flora cause a delay of the L. monocytogenes growth under 70% O2/30% CO2.

Practical Applications

Fresh poultry meat has become an increasingly popular food during the last 10 years due to its beneficial nutritional composition. From the microbiological point of view, raw poultry meat is sensitive for microbial growth because of its physical and chemical properties. In this context, the prediction of the growth of foodborne pathogenic bacteria e.g., Listeria monocytogenes is of vital importance to ensure a safe poultry production. Therefore, packaging under modified atmosphere conditions is widely established to improve the quality, shelf life as well as safety aspects. Taking into account that the growth of L. monocytogenes is also influenced by the natural spoilage flora of poultry reflects that interactions between the microorganisms have to be considered while packaging poultry filets under modified atmosphere conditions. The present study shows how two commonly used gas mixtures for poultry influence the outgrowth of L. monocytogenes in the presence of the natural background flora.

UK – Thornaby’s Anson Farm suspected food poisoning: Four more salmonella cases confirmed

Gazette Live

Public Health England says that 35 people have now tested positive at the Thornaby pub :: All cases are from before control measures put in place

The number of people who have tested positive for salmonella after eating at a Thornaby pub has risen again.

There have now been 81 people who have taken ill after eating at the Anson Farm on Teesside Industrial Estate last month.

Of that number, 35 have tested positive for salmonella – four more since Monday.

All those who have tested positive contracted the bug before the pub put in a series of control measures requested by PHE and Stockton Council environmental health officers in the week commencing May 18, confirmed a PHE spokesperson.
