Research – Retail Packed Chicken and Microorganisms

Food Safety News imagesCAYZ5I84

It won’t all harm you, but some of it might. That’s the caveat in the latest Consumer Reports analysis of tests on raw chicken breasts purchased at retailers nationwide. The analysis found that 97 percent of tested chicken breast samples “harbored bacteria that could make you sick.”

While it is true that the detected bacteria could cause infections if improperly handled, a smaller proportion has the potential to cause foodborne illness in the classic sense.

Research – High-Pressure Processing and Boiling Water Treatments for Reducing Listeria monocytogenes, Escherichia coli O157:H7, Salmonella spp., and Staphylococcus aureus During Beef Jerky Processing

Science Direct

Beef jerky is a convenient, ready-to-eat meat product, but requires processing lethality steps to ensure the safety of the product. Previous outbreaks involving various jerky products have highlighted the risks associated with jerky and the importance of utilizing pathogen interventions during processing. In this study, two alternative interventions were evaluated for reducing pathogen populations during jerky processing. Results demonstrated that high pressure processing (HPP; two treatments of 550 MPa, 60 s) could produce significant (p < 0.05), but variable reductions (6.83 and 4.45 log10 CFU/strip) of Salmonella spp. and Escherichia coli O157:H7, respectively, on resulting beef jerky. HPP treatments, however, produced minor reductions (p < 0.05) of Gram-positive pathogens, resulting in reductions of 1.28 and 1.32 log10 CFU/strip of Listeria monocytogenes and Staphylococcus aureus, respectively. Alternatively, boiling water (100 ± 2 °C) treatments (20–30 s) used after marination and prior to dehydration, reduced Salmonella spp., E. coli O157:H7, L. monocytogenes, and S. aureus populations >5.0 log10 CFU/strip in resulting beef jerky. Thus, 20 or 30 s boiling water (100 ± 2 °C) treatments could be effective interventions for commercial jerky processors or home food preservers. Future validation of these processes in-plant could provide processors and regulators with alternative strategies for safe and shelf-stable jerky products.

Research – Food Poisoning and Online Food Shopping

Liebert Open Access

Food sold over the internet is an emerging business that also presents a concern with regard to food safety. A nationwide foodborne disease outbreak associated with sandwiches purchased from an online shop in July 2010 is reported. Consumers were telephone interviewed with a structured questionnaire and specimens were collected for etiological examination. A total of 886 consumers were successfully contacted and completed the questionnaires; 36.6% had become ill, with a median incubation period of 18 h (range, 6–66 h). The major symptoms included diarrhea (89.2%), abdominal pain (69.8%), fever (47.5%), headache (32.7%), and vomiting (17.3%). Microbiological laboratories isolated Salmonella enterica serovar Enteritidis, Salmonella Virchow, Staphylococcus aureus, Bacillus cereus, and enterotoxigenic Escherichia coli from the contaminated sandwiches, Salmonella Enteritidis and Salmonella Virchow from the patients, and Salmonella Enteritidis and Staphylococcus aureus from food handlers. Pulsed-field gel electrophoresis genotyping suggested a common origin of Salmonella bacteria recovered from the patients, food, and a food handler. Among the pathogens detected, the symptoms and incubation period indicated that Salmonella, likely of egg origin, was the probable causative agent of the outbreak. This outbreak illustrates the importance of meticulous hygiene practices during food preparation and temperature control during food shipment and the food safety challenges posed by online food–shopping services.

USA – Texas – Shigella and Botulism Outbreaks

Shigella BlogShigella_stool

Shigella outbreak continues to hit Grayson County hard. Health Department officials say new cases are being reported every day.

News 12 last reported there were 36 cases just before Thanksgiving. But, in just 13 days that number has jumped to 61 confirmed cases in Grayson County.

A command center has been set up at the Health Department, where they say employees are working to stop Shigella from spreading.

Botulism Blog

On Friday, the Health Department was informed of the first potential case here in Amarillo. They soon began investigating and discovered three other possible cases.

Two of the patients matched the criteria and were given the antitoxin. Doctors say they are slowly improving.

All four patients are adults and are currently hospitalized.

“We’ve got a small group of people who know each other in some manner, we hope that there are no other cases, but we just want to do our due diligence and make sure that we are protecting our community by providing information,” Casie Stoughton who is the Assistant Director of the City of Amarillo Public Health Department.

Listeria: Why so deadly to the Elderly and Pregnant Women

Food Poisoning Bulletin – Full Article at this link.

Listeria is the common name for the pathogenic or disease-causing bacterium known as Listeria monocytogenes.  It is a foodborne bacterium that, when ingested, causes an infection known as listeriosis.[1]  Approximately 2,500 illnesses and 500 deaths are attributed to listeriosis in the United States annually.[2]

Listeria is ubiquitous in the environment, and can be isolated from wild and domestic animals, birds, insects, soil, wastewater, and vegetation.  The bacterium easily comes into contact with farm animals, as it has been found to be present in grazing areas, stale water, and poorly prepared animal feed.  In addition to being present in the environment, Listeria can live in the intestines of humans, animals, and birds for long periods of time without causing infection.

USA – Vibrio Outbreak Raw Oysters

Food Poisoning BulletinVibrio

Vibrio outbreak associated with eating raw oysters and raw clams has sickened at least 104 people in 13 states over the last six months, according to the Centers for Disease Control and Prevention (CDC). Six people have been hospitalized.

Public health investigators have traced the source of some of these illnesses to shellfish harvest areas in Connecticut, Massachusetts, New York, and Virginia. Massachusetts issued a recall of oysters,  Connecticut issued a recall of oysters and clams. Implicated harvest areas in Virginia were closed in July and remain closed.  In Massachusetts, they were closed in August and remain closed. In New York they were closed in June and reopened in mid-September. In Connecticut, they were closed in August and reopened in mid-September.

An NHS investigation has failed to find the source of a salmonella outbreak that hit Dundee toddlers.

Eight youngsters from the city’s Technotots nursery were struck down with salmonella, with NHS Tayside’s health protection team and city council environmental health officers launching a “wide-ranging” investigation.

However, they were unable to confirm where the Brunel Road nursery’s outbreak stemmed from.
