German Foodborne Virus Outbreak 6,500 Cases

Reuters

More than 6,500 German children and teenagers have fallen ill with diarrhea and vomiting that health authorities say has likely been caused by a food-borne virus in meals delivered to schools and day care centers.

Regional health ministries and a top health research institute said youngsters from five of Germany’s 16 states had been affected by the acute gastroenteritis, with the first cases registered on Tuesday. So far, those affected had not suffered any complications.

“All the institutions which have registered cases of the illness so far are probably being provided by the same caterer,” wrote the Robert Koch Institute, which researches and advises the German health ministry on infectious diseases. “This suggests that it is an outbreak caused by food.”

The German government and affected states have established a task force charged with looking for the reason for the illness in order to prevent it spreading any further.

US Alert – Hepatitis A Restaurant Worker

SIPH

Patrons of Tom’s Gyro, 150 N. 3rd Ave., in Pocatello may have been exposed to Hepatitis A during August 2nd-August 14th, as an employee there has been confirmed as having the disease. Currently, there is no evidence of a hepatitis A outbreak associated with Tom’s Gyros. While the risk to public health is low, the possibility exists that Tom’s Gyro patrons could have been exposed to hepatitis A. Tom’s Gyro has cooperated fully with the investigation into the situation. The employee is believed to have practiced good hand hygiene but could have inadvertently contaminated food and drinks at the restaurant. The risk of exposure is considered small, but not zero.

Australia – Hepatitis A Warning

NSW

South Eastern Sydney Local Health District today issued a health warning to patrons of a food outlet in the Sydney CBD following the diagnosis of Hepatitis A in a food preparation employee.

Public Health Director at South Eastern Sydney Local Health District, Professor Mark Ferson advised that people who ate food from Sumo Salad in Westpac Place, Kent Street, Sydney between Thursday 19 July and Thursday 26 July may need to receive a hepatitis A vaccine.

Patrons who ate food from the Sumo Salad from Wednesday 11 July to Wednesday 18 July are still at risk of hepatitis, but as the vaccine is only effective within 2 weeks of exposure, these people are not recommended to have vaccine, but should visit their GP if they develop symptoms.

Although the risk of infection to patrons is probably low, as a precaution a clinic providing a free hepatitis A vaccine will be available at Sydney Hospital, Macquarie Street Sydney. The clinic will also provide customers of Sumo Salad with an opportunity to speak to a nurse about possible exposure and any potential health risk.

The clinic will be open between 3pm and 7pm on Thursday, 2 August 2012 at Sydney Hospital’s general outpatient department, north block, entrance from Macquarie Street.

“Hepatitis A is a viral infection of the liver. The virus is spread by the faecal-oral route, including contaminated food or water or direct contact with an infected person,” Professor Ferson said.

Hepatitis A symptoms develop two to seven weeks after infection and include fever, feeling unwell, poor appetite, abdominal discomfort, jaundice (which is yellowing of the skin and eyes) and dark urine.

“There is no specific treatment for hepatitis A but the illness resolves after several days or weeks.

Professor Ferson said while a safe and effective vaccine is available against hepatitis A, it only prevents infection if given within 2 weeks of exposure. It will not protect those people who were exposed to the virus more than 2 weeks prior to vaccination.

“We urge anyone who may have been exposed to these food products to receive a Hepatitis A vaccination as quickly as possible to develop some protection from developing the infection,” he said.

”People who have already received hepatitis A vaccine or have had the disease would already be immune and will not need an injection.”

People can also contact the NSW Health Information Line 1300 066 055 for more information during business hours.

Canada – Advisory Alert Shellfish Vibro parahaemolyticus

CDC BC 

The BC Centre for Disease Control is reminding the public there’s a risk of illness associated with eating raw or undercooked bivalve shellfish such as oysters, clams, mussels, scallops, and cockles.

 Shellfish may accumulate bacteria(Vibrio parahaemolyticus), viruses (norovirus, hepatitis A), and toxins (paralytic shellfish poisoning, diarrhetic shellfish poisoning) or other impurities present in the water. Thorough cooking destroys bacteria and viruses, but does not destroy toxins.

 To date in 2012, five cases of locally-acquired Vibrio parahaemolyticus infection have been reported. In 2011, 42 cases of vibrio were reported. These illnesses have been linked to raw shellfish served in restaurants, bought at retail, or self-harvested in communities throughout the province including, Gibsons, Sechelt, Powell River, Ladysmith, Qualicum, Ucluelet, Gabriola Island, Cortes Island and Parksville.

In addition to individual cases, BC has also experienced outbreaks associated with shellfish. In 2010, an outbreak of norovirus from raw oysters affected over 30 people and in 2011 more than 60 people became ill after consuming cooked mussels contaminated with diarrhetic shellfish poisoning.

India – Hepatitis Outbreak – Kills 12 – Contaminated Water

BBC

An outbreak of Hepatitis E has killed at least 12 people and left 4,089 others unwell, officials in the western Indian state of Maharashtra said.

The outbreak happened in Ichalkaranji, a city of 300,000 people.

“The cause of the outbreak is contaminated water from the Panchganga river,” Dr LS Patil, a senior government doctor in the region, said.

Illicit Shellfish Trade Risking Health of Thousands?

The Independant

The illicit and highly-lucrative trade in shellfish is putting the health of many thousands of people at risk with tonnes of potentially contaminated seafood feared to be entering the food chain.

Health officials and food watchdogs are concerned that a boom in the illegal harvesting of cockles, clams and oysters for sale to restaurants and wholesalers threatens outbreaks of serious food poisoning.

The thriving seafood rustling industry, which sees unlicensed gangs of pickers target beaches and mudflats across the country to steal molluscs worth thousands of pounds at a time, has prompted a crackdown by the authorities. But with some pickers operating in organised gangs, fisheries protection bodies say they lack the resources to effectively tackle the problem.

With an annual value of at least £250m, the legitimate shellfish industry is a major part of Britain’s food economy. Properly gathered molluscs are subject to strict purification treatments, including ultra-violet light and filtering, to ensure they are fit for human consumption.

Hep A Incidence US Steakhouse

Food Poison Journal

The Vanderburgh County Health Department and the Indiana State Department of Health are investigating a case of Hepatitis A in a food worker at the Lone Star Restaurant located in the Eastland Place Shopping Center at 943 N. Green River Road Evansville IN, 47715-2418.

“We’ve been in contact with Lone Star and we wanted to let people know that they may have been exposed,” Dr. Ray Nicholson, Health Officer for the Health Department said.

Persons who were exposed and unvaccinated can receive a dose of Hepatitis A vaccine to help lessen the effects of the disease or prevent disease if given within 14 days of exposure. Persons who ate or drank at the Lone Star from April 20-April 26, 2012 could have been exposed to Hepatitis A, but should not receive vaccine because it is not effective for exposure past 14 days. Those people should seek medical care if they show symptoms of Hepatitis A.

Canada -Recall Hepatitis A Virus

CIFA 

The Canadian Food Inspection Agency (CFIA) and Overwaitea Food Group are warning the public not to consume the Western Family brand Pomeberry Blend berries described below. The affected product may contain Hepatitis A virus.

The affected product Western Family brand Pomeberry Blend berries is sold frozen in 600g packages bearing UPC 0 62639 31347 0. All lot codes are affected.

This product is known to have been distributed in British Columbia, Alberta, and Ontario and may also have been distributed to other provinces.

This recall is a result of an ongoing food safety investigation with BCCDC and regional health authorities into a number of cases of hepatitis A in British Columbia.

Food contaminated with Hepatitis A virus may not look or smell spoiled. Consumption of food contaminated with this virus may cause hepatitis and produce a self-limited disease that does not result in chronic infection or chronic liver disease. The illness is usually mild and starts about 15 to 50 days after the contaminated food is eaten. It generally goes away by itself in a week or two, although it can last up to 6 months in some people. It can cause inflammation of the liver, and symptoms may include fever, low appetite, nausea, vomiting, diarrhea, muscle aches, and yellowing in the whites of the eyes and the skin (jaundice).

Hepatitis A – 2011 Two Outbreaks in Europe

Eurosurveillence

In October 2011, two primary cases of hepatitis A virus (HAV) infection with identical HAV genotype IB strains to those seen in other outbreaks associated with semi-dried tomatoes were reported in England. Both cases had consumed semi-dried tomatoes. Epidemiological investigations revealed two additional cases of genotype IB strains with different sequences who also reported having consumed semi-dried tomatoes. In November, five cases of HAV infection with closely related strains were identified in the Netherlands. A foodborne multiple-strain outbreak is suspected.

Euroserveillance

In November 2011, a cluster of initially five cases of hepatitis A infection with closely related strains was identified in the Netherlands. England reported possibly related cases. Strains with identical sequences had been involved in previous outbreaks linked to semi-dried tomatoes. Investigation of the Dutch cluster suggested a link with ready-to-eat salads including those containing semi-dried tomatoes. Despite trace-back, a source was not identified. Vigilance is needed, and rapid sharing of data may help source-tracing.
