USA – Hawaii – E.coli O157 Outbreak

Food Poisoning Journal

Lisa Kubota of Hawaii News Now reports that investigators with the Hawaii Department of Health are looking into at least nine people have now become ill from E. coli O157:H7.  The confirmed cases consist of three adults and six children. All of them live on Oahu except for a Canadian visitor who spent time on Oahu, but was later diagnosed on the Big Island. Officials are having trouble pinpointing the source of the infections.

Oahu healthcare providers recently received a letter from health officials warning them to be on the lookout for E. coli O157:H7. Around the same time, Dr. James Ireland saw a 67-year-old patient with symptoms like severe diarrhea and abdominal cramps.  Ireland said the man is now recovering after being hospitalized. There have been a total of 11 cases so far this year, including two unrelated to the current cluster. There were 20 last year, 9 the previous year, and 29 in 2010.

According to the state, three of the children in this latest group developed a life-threatening complication called Hemolytic Uremic Syndrome.

Research – Cranberry Antimicrobial – Multiple PCR for Pathogens

Science Direct

The antimicrobial properties of the American cranberry were studied against Escherichia coli O157:H7, Listeria monocytogenes, and Lactobacillus rhamnosus to determine the effects on growth inhibition, membrane permeability, and injury. Cranberry powder was separated using a C-18 Sep-Pak cartridge into sugars plus organic acids (F1), monomeric phenolics (F2), and anthocyanins plus proanthocyanidins (F3). Fraction 3 was further separated into anthocyanins (F4) and proanthocyanidins (F5) using an LH-20 Sephadex column. Each fraction was diluted in the brain heart infusion (BHI) broth to determine the minimum inhibitory/bactericidal concentrations (MIC/MBC). L. monocytogenes was the most susceptible to cranberry fraction treatment with the lowest MIC/MBC for each treatment, followed by E. coli O157:H7 and L. rhamnosus. Membrane permeability and potential was studied using LIVE/DEAD viability assay and using Bis (1, 3-dibutylbarbituric acid) trimethine oxonol (DiBAC4), respectively. L. rhamnosus demonstrated the highest permeability followed by E. coli O157:H7, and L. monocytogenes. L. rhamnosus demonstrated the highest recovery followed by E. coli O157:H7, and L. monocytogenes. Each cranberry fraction demonstrated membrane hyperpolarization at their native pH, while F2, F3, and F5 demonstrated membrane depolarization at neutral pH. With this knowledge cranberry compounds may be used to prevent maladies and potentially substitute for synthetic preservatives and antibiotics.

We developed a rapid and reliable technique for simultaneous detection of Salmonella Typhimurium, Escherichia coli O157:H7 and Listeria monocytogenes that can be used in food products. Magnetic nano-beads (MNBs) based immunomagnetic separation (IMS) was used to separate the target bacterial cells while multiplex PCR (mPCR) was used to amplify the target genes. To detect only the viable bacteria, propidium monoazide (PMA) was applied to selectively suppress the DNA detection from dead cells. The results showed the detection limit of IMS-PMA-mPCR assay was about 102 CFU/ml (1.2 × 102 CFU/ml for S. Typhimurium, 4.0 × 102 CFU/ml for E. coli O157:H7 and 5.4 × 102 CFU/ml for L. monocytogenes) in pure culture and 103 CFU/g (5.1 × 103 CFU/g for S. Typhimurium, 7.5 × 103 CFU/g for E. coli O157:H7 and 8.4 × 103 CFU/g for L. monocytogenes) in spiking food products samples (lettuce, tomato and ground beef). This report has demonstrated for the first time, the effective use of rapid and reliable IMS combined with PMA treatment and mPCR assay for simultaneous detection of viable S. Typhimurium, E. coli O157:H7 and L. monocytogenes in spiked food samples. It is anticipated that the present approach will be applicable to simultaneous detection of the three target microorganisms for practical use.

USA – Seattle – E.coli O157 Restaurant Based Outbreak

E.coli Blog

King County Public Health agency shut down an Ethiopian restaurant in Seattle’s central district on Wednesday afternoon after connecting the establishment to an outbreak of E. coli O157:H7, health agency spokeswoman Kathryn Ross has confirmed to Food Safety News.

At least two people have fallen ill in the outbreak, and Ross said the likelihood of others being sickened is uncertain.

In its closure notification, the agency cited Ambassel Ehtiopian Cuisine & Bar with five safety violations, including the outbreak.

Other violations included foods not being protected from cross-contamination, improperly sanitized equipment, and poor personal hygiene among employees due to inadequate handwashing facilities.

E.coli O157 present in Gouda Herb Cheese by Kilshanny Farmhouse Cheese

Wednesday, 27 February 2013

Summary
Category 1: For Action
Alert Notification: 2013.05
Product: Kilshanny Farmhouse Cheese Gouda Herb Cheese: approval number: IE 1859 EC
Batch Code: production date: 19/09/2012
Country Of Origin: Ireland

Message:

E.coli O157 has been found in a batch of Gouda herb cheese by Kilshanny Farmhouse Cheese. This product has been sold in a foodstall in the Limerick Milk Market and in a retailer in Co. Clare. The company has been ordered by the Department of Agriculture, Food and the Marine to withhold placing any further batches on the market.  Consumers are advised not to eat the implicated cheese due to the presence of E.coli O157.

Nature Of Danger:

E.coli O157 may cause severe bloody diarrhoea and abdominal cramps, although sometimes the infection causes non-bloody diarrhoea or no symptoms. In some groups, particularly children under 5 years of age and the elderly, the infection can also cause a complication called haemolytic uraemic syndrome (HUS), in which the red blood cells are destroyed and the kidneys fail.

Consumers are advised not to eat the implicated cheese.
