At least 170 people have become ill after having been at a Christmas party at Klækken hotels on Ringerike the weekend. Possible virus.

CDC

Noroviruses are responsible for more than half of all reported outbreaks of gastroenteritis (vomiting, diarrhea, and stomach cramping caused by inflammation of the stomach and intestines). While the vast majority of norovirus illnesses are not part of a recognized cluster, outbreaks provide important information on how the virus spreads and, therefore, how best to prevent infection.

Norovirus outbreaks occur throughout the year. But, over 80% of the outbreaks occur from November to April. Also, when there are new strains of norovirus, the number of outbreaks tends to increase periodically. This occurred in the winter of 2006 to 2007 with the Minerva strain. However, a new strain that appeared in 2009 (New Orleans) did not lead to more outbreaks.

Most outbreaks are caused when norovirus is spread from infected people to others. But, the virus can also spread by consuming contaminated food or water and touching things that have the virus on them. People can get norovirus illness many times during their lifetime. Outbreaks can affect people of all ages and in a variety of settings.

The Guardian

A dream Christmas cruise has turned into the holiday from hell, according to passengers who claim as many as 400 travellers have been struck down with the norovirus winter vomiting bug.

One traveller aboard the P&O liner Oriana, which is on a 10-night Baltic cruise out of Southampton visiting Christmas markets, said people felt like they were sailing on a “plague ship”.

What do norovirus and baked-on lasagna have in common? Both can survive the dishwasher.

Researchers at Ohio State University have made a discovery that may help to explain why restaurants have a hard time controlling the spread of norovirus, the leading cause of food poisoning worldwide. About half of all foodborne illness outbreaks in the US are caused by norovirus, most of them, about 80 percent, happen between November and April, according to the Centers for Disease Control and Prevention (CDC).

USA – Another Raw Milk Recall – Possible Food Poisoning

Food Poisoning Bulletin

Raw milk produced by Kimberton Farms Dairy and sold at the Kimberton Whole Foods co-sops in Pennsylvania has been removed from store shelves after a number of illnesses were reported by consumers who drank the milk,  according to the Chester County Health Department. Those sickened have reported food poisoning symptoms that include bloody diarrhea, vomiting and abdominal cramping.

Kimberton Farms Dairy, of Kimberton, Pa., also known as Camp Hill Village or Kimberton Hills supplied the milk to  Kimberton Whole Foods co-op which sold the product at its Kimberton and Downingtown stores. The product has been removed from those locations.

Raw milk, milk that has not been pasteurized, can carry many types of disease-causing germs such as Campylobacter, E. coli, Listeria, Salmonella, Yersinia, and Brucella. These bacteria can cause severe illness with symptoms listed above. Sometimes hospitalization is required. Those most at risk include small children, pregnant women, and others with compromised immune systems. For more information, see the fact sheet produced by the Pennsylvania Department of Health. Or, check out the raw milk information compiled by the Centers for Disease Control and Prevention (CDC).

 

Research – E.coli O157 Testing in Water

Science Direct

The performances of three chromogenic agars were evaluated for the recovery of Escherichia coli O157:H7 from spiked de-chlorinated tap, ground and surface water, and treated drinking water samples. The chromogenic agars: ChromAgar O157 (CHROM), Rainbow Agar O157 (RB) and HiCrome EC O157 (HC) were compared to cefixime-tellurite Sorbitol MacConkey (CT-SMAC), commonly used for the isolation of E. coli O157:H7. Confirmation of suspect E. coli O157:H7 colonies were performed by colony real-time PCR (C-RTi-PCR) based on the presence of Shiga-toxin genes (stx1 and stx2). Recovery of inoculated E. coli O157:H7 from de-chlorinated tap water indicated that RB and CHROM agars demonstrated improved recovery when compared to HC or CT-SMAC. There was a significant drop in recovery on all agars tested after 120 hours (day 5). Twenty de-chlorinated tap and/or treated drinking water samples were inoculated with a pure culture of E. coli O157:H7 (ATCC 43894), and a mixed culture of E. coli O157:H7 (ATCC 43894), E. coli strain K-12, and Enterococcus faecalis (ATCC 063589). After a 48 hour holding time, the recovery using CHROM (99 %) and HC (12 %) from samples contaminated with the pure culture were found to be significantly different (p < 0.05). Recovery results using CHROM (39 %) and CT-SMAC (32 %) from samples contaminated with the mixed culture after 48 hour holding time were not significantly different (p > 0.05). Analysis by C-RTi-PCR of forty five environmental water samples (surface, sewage, and final effluents) which were negative for E. coli O157:H7 showed an incidence of false suspect positive colonies of 38 % (CHROM), 53 % (RB), 58 % (HC), and 91 % (CT-SMAC). Further analysis of eight of the environmental samples inoculated with E. coli (ATCC 43894) showed 100% recovery when utilizing CHROM, 50% when using RB and 40 % when using HC. In addition, the C-RTi-PCR positive confirmation rate was 100% for CHROM and HC and 65% for RB. CHROM demonstrated improved recovery of E. coli O157:H7 over RB, HC, and CT-SMAC in terms of sensitivity and specificity.

Research – New study sheds light on how Salmonella spreads in the body

Eureka Alert

Findings of Cambridge scientists, published today in the journal PLoS Pathogens, show a new mechanism used by bacteria to spread in the body with the potential to identify targets to prevent the dissemination of the infection process.

Salmonella enterica is a major threat to public health, causing systemic diseases (typhoid and paratyphoid fever), gastroenteritis and non-typhoidal septicaemia (NTS) in humans and in many animal species worldwide. In the natural infection, salmonellae are typically acquired from the environment by oral ingestion of contaminated water or food or by contact with a carrier.  Current vaccines and treatments for S. enterica infections are not sufficiently effective, and there is a need to develop new therapeutic strategies.

Dr Andrew Grant, lead author of the study from the University of Cambridge, said: “A key unanswered question in infectious diseases is how pathogens such as Salmonella grow at the single-cell level and spread in the body.  This gap in our knowledge is hampering our ability to target therapy and vaccines with accuracy.”

In otherwise healthy people, salmonellosis may cause short-term symptoms such as high fever, severe headache, vomiting, nausea, abdominal pain and diarrhoea. Long-term complications may include severe arthritis.

The importer / packer, Compass Food Sales, Aurora, ON is voluntarily recalling the affected product from the marketplace. The CFIA is monitoring the effectiveness of the recall.

Research – Safer Spinach Combined Microbiological Control

Science Direct

University of Illinois scientists have found a way to boost current industry capabilities when it comes to reducing the number of E. coli 0157:H7 cells that may live undetected on spinach leaves.

“By combining continuous ultrasound treatment with chlorine washing, we can reduce the total number of foodborne pathogenic bacteria by over 99.99 percent,” said Hao Feng, a U of I professor of food science and human nutrition.
