Nobody wants to talk about it but the secret is out of the golf bag - 30 people got violently ill with diarrhea, nausea and vomiting after the Thanksgiving Day buffet at one of the most prestigious clubs in London - the London Hunt and Country Club. CJBK's Steve Garrison, presenting them with the facts, has forced The London Middlesex Health Unit to confirm the incident. They confirm the outbreak of the Norwalk virus but can't say how it arrived at the club suggesting it could have come from a food handler, a guest, from the food itself, they just don't know. Meanwhile, two restaurants in London where nobody got sick, were forced to put a yellow caution sign in their front window because of mice droppings in the kitchen. They took a hit in the media, the Hunt club escaped any coverage of their incident for roughly 2 weeks until we forced the health unit to confirm the story. Not everything in life is fair. We'll see if the London Free Press now has the moxy to run the Hunt club story.

Food borne parasites play a major role as disease causing organisms worldwide. They include meat borne tissue parasites like Trichinella spiralis and Toxoplasma gondii, and intestinal parasites that may contaminate both food and water like Cryptosporidium and Giardia. Most food borne parasites are zoonotic.

Noroviruses are important causes of infective foodborne gastroenteritis.
The noroviruses (former called Norwalk virus), members of the Caliciviridaefamily, are pathogens with a world wide distribution. Due to the induction of short-term immunity, the human population is very susceptible to infections with these viruses. Outbreaks of norovirus gastroenteritis are typically caused by food and drinking water contaminated with faeces or sewage.

Parasites and Foodborne Illness
*
Parasites may be present in food or in water and can be identified as causes of foodborne or waterborne illness in the United States. They range in size, from tiny single-celled organisms to worms visible to the naked eye. Their lifecycle may also vary. While some parasites use a permanent host, others go through a series of developmental phases using different animal or human hosts. The illnesses they can cause range from mild discomfort to debilitating illness and possibly death.

TORBAY Hospital : ...we had many more norovirus cases to deal with...
Hospital has 'robust plan' to deal with problems posed by winter
By Olivier Vergnault Overgnault@Heraldexpress.co.uk
TORBAY Hospital has prepared a 'robust winter plan' to deal better with an influx of patients during winter.
Paul Mears, chief operating officer with South Devon Healthcare Trust, told a board meeting this week that the hospital had been stretched last winter because of prolonged difficult weather conditions.
He said: "It has been challenging in terms of the tough weather conditions which led to a rising number of injuries.
"We also had to prepare for the swine flu epidemic and we had many more norovirus cases to deal with.
"It had a bigger impact on the accident and emergency department and the four-hour standard, and had an adverse impact on the ambulance turnaround performance."
As part of the plans, a better bed management policy has been put in place, while senior physicians will be on site at all times to ensure that patients can be appropriately treated, admitted and discharged.
Mr Mears said electronic whiteboards had been installed throughout the hospital to give nurses and doctors access to every bed and improve discharge efficiency.
In his report to the board he said: "This year for the first time we are holding a winter planning seminar for all matrons from the acute trust together with matrons from community hospitals and key community staff."
However, he warned that despite the measures taken to make sure that Torbay Hospital coped well during the winter months, social care budgets could go up, causing a challenge to the transfer of patients to community beds.
The hospital also needed to be ready for staffing problems when nurses and doctors were sick.
Mr Mears' report added: "The risk of norovirus remains high. We are working with our infection control teams to ensure that appropriate measures are in place to ensure that our policies for managing infection are effective."
Meanwhile, people across South Devon are being encouraged to protect themselves from flu this winter by having a vaccination.
This year's annual seasonal flu vaccination campaign has now been launched by the Department of Health.
This year, for the first time, all pregnant women will be offered the seasonal flu vaccination.
It will protect them against the H1N1 virus (swine flu) that will still be circulating this winter, and pregnant women who catch this strain are at an increased risk of severe disease and flu-related hospital admissions.
Everyone aged 65 and over is routinely offered the jab, as are younger people with long-term conditions such as heart disease, diabetes, asthma, multiple sclerosis and serious kidney and liver disease.
Around 15 million people in the UK have the jab, which must be administered every year, as it is altered to match the flu strains which are in circulation.

Sick restaurant workers trudge into work regardless, study says
A new study suggests consumers may have more to worry about when dining out than the bill. The restaurant workers’ union, Restaurant Opportunities Centers United, conducted a study involving more than 4,000 workers; the majority of whom admitted to working while sick.
Sixty-three percent of restaurant employees said they cooked or served food while ill during the last 12 months because they needed the money.
Many foodborne illnesses can be spread from person-to-food, with the potential to sicken hundreds of people. Diseases such as Salmonella, E. coli and Norovirus can be transmitted from sick food handlers who don’t wash their hands properly or handle ready-to-eat foods and utensils. In April, sick food workers at an Illinois Subway restaurant sickened at least 125 people with Shigella, hospitalizing 13 people.
ROCU argues the study highlights the need for more paid sick days to protect workers and consumers.
"The main thing that I think I took away from the research was that when restaurant workers are unhealthy, there's a real potential for consumers to be unhealthy," ROC Policy Coordinator Jose Oliva said to The News-Herald. "In the context of this great recession, we're seeing that employers are pushing workers more and more, and that's manifested in a lot more workers in restaurants working longer hours and doing it for less pay. As the study demonstrates, they are without some basic standards, as well as health insurance."
Other alarming statistics the study found:
-38 percent of workers said they had done something while working that put their safety at risk.
-36 percent said their kitchens sometimes get so hot that conditions are unsafe.
-Almost half said they had been either cut or burned on the job.
-Almost 90 percent don’t get health insurance through their employers.

Infections à ROTAVIRUS de l’enfant : Des souches émergentes pour les futurs vaccins ?
Infections à ROTAVIRUS de l’enfant : Des souches émergentes pour les futurs vaccins ?
Les rotavirus sont la cause principale des gastro-entérites aiguës de l’enfant. Dans le cadre de la vaccination, une surveillance prospective est requise pour caractériser les infections à rotavirus et détecter l’émergence de souches à risque épidémique. Plusieurs équipes ont participé de 2006 à 2009 à une enquête en ce sens. Si la stabilité génotypique des rotavirus en France assure l’efficacité vaccinale à court et moyen terme, les souches G12 et G8 susceptibles d’émerger dans l’avenir doivent être prises en compte dans de futurs vaccins.
Cette enquête a effectué le recueil et l’analyse des selles d’enfants admis aux urgences pédiatriques de 13 CHU pour diarrhées. Les rotavirus ont été détectés puis génotypés par la technique de PCR en temps réel (RT-PCR).
Sur 1.947 rotavirus génotypés, les souches G1 (61,7 %) et G9 (27,4 %) étaient prédominantes et stables, suivies de G2 (6,5 %), G3 (4 %) et G4 (2,5 %), majoritairement associées avec P[8] (92,9 %), au total 31 souches atypiques et réassortants potentiellement zoonotiques, notamment G12 et G8, certaines étant génétiquement proches de souches bovines. Les souches G12 et G8 seraient susceptibles d’émerger dans l’avenir doivent être prises en compte dans de futurs vaccins. Il faut poursuivre la surveillance pour maîtriser l’émergence de nouveaux réassortants échappant aux vaccins actuels.
Chez le jeune enfant, les rotavirus du groupe A sont responsables dans le monde de 29 à 45 % des hospitalisations pour gastro-entérites aiguës (GEA) et diarrhées sévères, avec plus de 600.000 décès annuels, surtout dans les pays où malnutrition et mauvais état des structures sanitaires alourdissent le pronostic. Afrique et Asie concentrent 80 % des décès par diarrhée. Si une prise en charge thérapeutique rapide et adaptée a permis de réduire considérablement la mortalité, les GEA ont un surcoût annuel en termes de dépense de santé et de perte de temps de travail pour les parents.
Une couverture vaccinale inférieure à 10% : Le développement de vaccins doit prévenir spécifiquement les formes sévères de GEA dans les deux premières années de vie. Deux vaccins vivants atténués oraux sont disponibles : Rotarix ® monovalent de GSK, RotaTeq® polyvalent de Sanofi-Pasteur-MSD. Leur introduction au calendrier vaccinal dans le monde a permis une nette diminution des consultations et hospitalisations pour GEA à rotavirus et de la mortalité avec un aplatissement de la courbe épidémique. En France, ces infections entraînent environ 300.000 épisodes par an de diarrhée aiguë chez les enfants de moins de 5 ans avec près de 140.000 consultations et 18.000 hospitalisations, le décès restant exceptionnel (moyenne : 13-14/an chez les moins de 3 ans). Coût annuel estimé : 28 millions d’euros. Le taux de couverture vaccinale est actuellement inférieur à 10 %.
Emergence de souches de génotypes G inhabituels : La biologie moléculaire a permis une meilleure compréhension de l’épidémiologie des rotavirus. Si, globalement, les souches sont différentes d’une espèce animale à l’autre, il n’existe pas de barrière d’espèces stricte, la transmission inter-espèces est possible, en particulier de l’animal à l’Homme. Ainsi, sur la base de leurs protéines externes de capside VP7 (type G) et VP4 (type P), induisant toutes deux des anticorps neutralisants, les rotavirus du groupe A peuvent être classés selon 19 génotypes G et 31 génotypes P, d’où une diversité considérable de souches. Les études montrent que 5 combinaisons génotypiques sont responsables de plus de 90 % des infections à rotavirus chez l’Homme. Des souches de génotypes G inhabituels émergent dans le monde, notamment dans les régions tropicales, et sont pour certaines des rotavirus animaux qui ont pu passer à l’Homme. La connaissance moléculaire des rotavirus circulants, de leurs dérives antigéniques ou de leurs réassortiments avec des souches humaines ou animales, est nécessaire pour assurer adéquation et efficacité des formules vaccinales. Pour cela doit être entreprise la surveillance des dérives antigéniques des rotavirus se produisant sous la pression immunitaire et des réassortiments potentiels entre souches humaines et animales.
Optimiser la prise en charge des GEA : Si en juin 2009, l’OMS avait demandé l’inclusion du vaccin anti-rotavirus dans les programmes nationaux de vaccination des enfants, en France, la vaccination anti-rotavirus des nourrissons de moins de 6 mois n’est actuellement pas recommandée dans le calendrier vaccinal 2010, mais le Haut Conseil de la santé publique (HCSP) rappelle l’importance des actions nécessaires pour améliorer la prise en charge des GEA et les pratiques de réhydratation orale du nourrisson. Dans l’éventualité où ces vaccins viendraient à être plus largement administrés, le Réseau rotavirus pourrait assurer surveillance et évaluation de l’efficacité de la vaccination, de l’effet possible sur la diversité des rotavirus circulants et de la détection des souches atypiques émergentes qui pourraient échapper à l’immunité vaccinale.
Des études à grande échelle sur les infections à rotavirus permettraient d’optimiser la stratégie vaccinale afin d’assurer la meilleure protection possible chez les jeunes enfants susceptibles d’être vaccinés.

Les rotavirus sont la cause principale des gastro-entérites aiguës de l’enfant. Dans le cadre de la vaccination, une surveillance prospective est requise pour caractériser les infections à rotavirus et détecter l’émergence de souches à risque épidémique. Plusieurs équipes ont participé de 2006 à 2009 à une enquête en ce sens. Si la stabilité génotypique des rotavirus en France assure l’efficacité vaccinale à court et moyen terme, les souches G12 et G8 susceptibles d’émerger dans l’avenir doivent être prises en compte dans de futurs vaccins.
Cette enquête a effectué le recueil et l’analyse des selles d’enfants admis aux urgences pédiatriques de 13 CHU pour diarrhées. Les rotavirus ont été détectés puis génotypés par la technique de PCR en temps réel (RT-PCR).
Sur 1.947 rotavirus génotypés, les souches G1 (61,7 %) et G9 (27,4 %) étaient prédominantes et stables, suivies de G2 (6,5 %), G3 (4 %) et G4 (2,5 %), majoritairement associées avec P[8] (92,9 %), au total 31 souches atypiques et réassortants potentiellement zoonotiques, notamment G12 et G8, certaines étant génétiquement proches de souches bovines. Les souches G12 et G8 seraient susceptibles d’émerger dans l’avenir doivent être prises en compte dans de futurs vaccins. Il faut poursuivre la surveillance pour maîtriser l’émergence de nouveaux réassortants échappant aux vaccins actuels.
Chez le jeune enfant, les rotavirus du groupe A sont responsables dans le monde de 29 à 45 % des hospitalisations pour gastro-entérites aiguës (GEA) et diarrhées sévères, avec plus de 600.000 décès annuels, surtout dans les pays où malnutrition et mauvais état des structures sanitaires alourdissent le pronostic. Afrique et Asie concentrent 80 % des décès par diarrhée. Si une prise en charge thérapeutique rapide et adaptée a permis de réduire considérablement la mortalité, les GEA ont un surcoût annuel en termes de dépense de santé et de perte de temps de travail pour les parents.
Une couverture vaccinale inférieure à 10% : Le développement de vaccins doit prévenir spécifiquement les formes sévères de GEA dans les deux premières années de vie. Deux vaccins vivants atténués oraux sont disponibles : Rotarix ® monovalent de GSK, RotaTeq® polyvalent de Sanofi-Pasteur-MSD. Leur introduction au calendrier vaccinal dans le monde a permis une nette diminution des consultations et hospitalisations pour GEA à rotavirus et de la mortalité avec un aplatissement de la courbe épidémique. En France, ces infections entraînent environ 300.000 épisodes par an de diarrhée aiguë chez les enfants de moins de 5 ans avec près de 140.000 consultations et 18.000 hospitalisations, le décès restant exceptionnel (moyenne : 13-14/an chez les moins de 3 ans). Coût annuel estimé : 28 millions d’euros. Le taux de couverture vaccinale est actuellement inférieur à 10 %.
Emergence de souches de génotypes G inhabituels : La biologie moléculaire a permis une meilleure compréhension de l’épidémiologie des rotavirus. Si, globalement, les souches sont différentes d’une espèce animale à l’autre, il n’existe pas de barrière d’espèces stricte, la transmission inter-espèces est possible, en particulier de l’animal à l’Homme. Ainsi, sur la base de leurs protéines externes de capside VP7 (type G) et VP4 (type P), induisant toutes deux des anticorps neutralisants, les rotavirus du groupe A peuvent être classés selon 19 génotypes G et 31 génotypes P, d’où une diversité considérable de souches. Les études montrent que 5 combinaisons génotypiques sont responsables de plus de 90 % des infections à rotavirus chez l’Homme. Des souches de génotypes G inhabituels émergent dans le monde, notamment dans les régions tropicales, et sont pour certaines des rotavirus animaux qui ont pu passer à l’Homme. La connaissance moléculaire des rotavirus circulants, de leurs dérives antigéniques ou de leurs réassortiments avec des souches humaines ou animales, est nécessaire pour assurer adéquation et efficacité des formules vaccinales. Pour cela doit être entreprise la surveillance des dérives antigéniques des rotavirus se produisant sous la pression immunitaire et des réassortiments potentiels entre souches humaines et animales.
Optimiser la prise en charge des GEA : Si en juin 2009, l’OMS avait demandé l’inclusion du vaccin anti-rotavirus dans les programmes nationaux de vaccination des enfants, en France, la vaccination anti-rotavirus des nourrissons de moins de 6 mois n’est actuellement pas recommandée dans le calendrier vaccinal 2010, mais le Haut Conseil de la santé publique (HCSP) rappelle l’importance des actions nécessaires pour améliorer la prise en charge des GEA et les pratiques de réhydratation orale du nourrisson. Dans l’éventualité où ces vaccins viendraient à être plus largement administrés, le Réseau rotavirus pourrait assurer surveillance et évaluation de l’efficacité de la vaccination, de l’effet possible sur la diversité des rotavirus circulants et de la détection des souches atypiques émergentes qui pourraient échapper à l’immunité vaccinale.
Des études à grande échelle sur les infections à rotavirus permettraient d’optimiser la stratégie vaccinale afin d’assurer la meilleure protection possible chez les jeunes enfants susceptibles d’être vaccinés.

CFIA Warns Consumers Against Pacific Rim Oysters
Submitted by Gene Rickman on Sat, 10/02/2010 - 12:16 Health TNM Canada
The Canadian Food Inspection Agency (CFIA) has urged the consumers to steer clear of Pacific Rim oysters as they are suspected to contain norovirus.
In the previous week also, CFIA issued a warning about Effingham extra small raw oysters that were processed at Albion Fisheries and Sea World Fisheries in Vancouver.
The tainted Pacific Rim Petite raw oysters are from the lot numbers 1091501 and 1092204. The original lot numbers may not be available, as many oysters have already been dispatched to restaurants and several retail outlets.
The CFIA had also said that oysters contaminated with food-borne pathogens may look or smell fresh, so the consumers should be careful while eating the oysters. A person may suffer from nausea, vomiting, diarrhea, abdominal pain, fever, headache, neck stiffness, and dizziness, if he/she consumes the contaminated oysters.
The most vulnerable people are young children, pregnant women, and elderly people with weak immune system.
In order to inquire about the contaminated product, the consumers can contact the CFIA at 1-800-442-2342.
The B. C. Centre for Disease Control (BCCDC) says that in order to kill the virus, it is very essential to cook the oysters at an internal temperature of 90 C.
Norovirus generally spreads from one person to another person and oysters can carry the virus, if they are contaminated by waste water carried away in sewers and drains.

Norovirus Linked to Raw Oysters
Norovirus Linked to Raw Oysters
The BCCDC is urging restaurant owners and consumers to avoid serving and consuming raw or undercooked Effingham XSM (extra small) oysters harvested between September 7 and September 21, 2010.
Vancouver Coastal Health has identified three clusters of persons reporting diarrhoea and other intestinal symptoms among consumers who ate raw oysters at events and restaurants in Vancouver and Richmond. The Canadian Food Inspection Agency (CFIA) confirmed that all three clusters were linked to batches of oysters harvested between September 7th and 14th (specifically, Effingham XSM (extra small) raw oysters with lot numbers 172688, 172929, and NY-OY-10091401). The CFIA has initiated a recall of these products. More information about the recall can be found at: http://www.inspection.gc.ca/english/corpaffr/recarapp/2010/20100923be.shtml
Other lots of Effingham XSM (extra small) raw oysters harvested between September 7 and September 21, 2010 have been distributed throughout BC.
RAW, UNDERCOOKED OYSTER CONSUMPTION ADVISORY is date is noted on the shellfish harvest tag that accompanies all oysters, although this information may not be available to consumers. We urge consumers and restaurant owners to cook Effingham XSM oysters.
Oysters are grown in coastal waters and feed by filtering large amounts of water through their gills. In water contaminated with norovirus, this can lead to the accumulation of the virus within the flesh and gut of the oyster. Viruses cannot be removed from oysters through cleaning. However, cooking kills norovirus and other organisms that can cause gastrointestinal illness.
To reduce the risk of illness, you should cook oysters thoroughly, making sure they reach 90ºC (195ºF) for 90 seconds by checking with a meat thermometer. You can also reduce the risk of illness by buying shellfish only from approved sources.
Symptoms of the reported illness include nausea, vomiting, diarrhoea, and stomach cramps. Most people showed symptoms within 48 hours of eating raw oysters and recovered in one to two days. These symptoms are typical of viral gastroenteritis caused by norovirus.
BCCDC, along with regional Health Authorities and partners within the federal and provincial governments are investigating the cause of this outbreak and have been working with the shellfish industry to reduce the risk of contamination in commercially harvested shellfish.
Anyone becoming ill with diarrhea and vomiting after eating shellfish should report their illness to their local public health department listed in the Blue Pages of the telephone book, or call HealthLink BC at 8-1-1. If symptoms are severe or persist, they should see their physician.
