Campylobacter

  • Posted: February 3rd, 2012 - 5:58am by Doug Powell

    Health Protection Scotland (HPS) said it had recorded 253 positive cases of E. coli during 2011, up from 212 the previous year.

    The agency blamed the increase on a UK-wide outbreak believed to have originated from contaminated vegetables. The outbreak, between December 2010 and July 2011, saw 250 cases of E. coli infection throughout England, Wales and Scotland and 74 victims treated in hospital.

    A subsequent investigation pointed to a possible link between leeks and potatoes bought loose and prepared in the home.

    However, the HPS report also noted that the apparent spike in E. coli between 2010 and 2011 was partly due to the unusually low rate of E. coli infection in 2010.

    The report also noted decreases in salmonella and campylobacter.
    In 2011, HPS received reports of 736 cases of salmonella infection – a decrease of almost 22% on the 941 reported in 2010.

    Cases of campylobacter were also down 3.6% to 6366 last year, although the figure remains "one of the highest on record."

    The Maryland health department has found bacteria in two bottles of raw milk produced by Pennsylvania’s Family Cow as the number of people sickened in the campylobacter outbreak on Thursday grew to 35 in four states -- including 28 confirmed cases in Pennsylvania, four in Maryland and one in New Jersey.

    The Maryland Department of Health and Mental Hygiene Laboratories Administration confirmed the presence of Campylobacter jejuni in two unopened raw milk samples purchased from The Family Cow farm, according to a department news release issued Wednesday.

    The final test results of samples taken at the farm by the Pennsylvania Department of Health on Friday and Monday may be available on Friday, according to Agriculture Department Press Secretary Samantha Krepps.

     

     

    And because public health types don’t have enough to do, New Jersey moved a step closer today to approving on-farm sales of raw milk.

    According to the Pennsylvania Department of Health, the number of confirmed cases of Campylobacter infection has increased to a total of 20 confirmed cases – 16 cases have been confirmed in Pennsylvania and and four cases in Maryland.

    Testing of the product is still underway at the Department of Agriculture.

    Samantha Krepps, Press Secretary for the Department Of Agriculture told Fox 43, "Once the family found out there was a problem - they voluntarily stopped production."

    The number of confirmed cases of campylobacter infection has increased to 12 -- eight in Pennsylvania residents and four in Maryland residents.

    Edwin Shank, the owner of Shankstead EcoFarm, trading as The Family Cow in Chambersburg, Pennsylvania, voluntarily halted the sale of milk today but insisted that raw milk samples that the farm sent last week to QC Labs has tested negative for pathogens.

    In an e-mailed letter to customers, Shank wrote:

    “In spite of some over-eager reporting, there have been NO positive campylobacter tests from unopened container of our raw milk either by the PDA lab or from QC Labs, the certified lab that we use. There are 4 samples, between us and the PDA which are being tested presently. We expect them later today.

    “When your emails started pouring in, one thing became immediate obvious. There is an unusually powerful stomach and lower gastrointestinal illness with acute 7-10 day diarrhea going through our communities. Some say it’s nationwide.

    “So, if we were looking for an easy way out, and looking to shift the blame, it looks like we could have our answer. It’s not us! It’s not our milk! It’s a virus. It’s the flu. It is nationwide so don’t blame us!”

    Testing of the product is still underway at the Pennsylvania Department of Agriculture, which will update the situation daily, according to a spokeswoman.

    Epidemiology and DNA fingerprinting are much better tools for solving outbreaks of foodborne illness than simple testing.

    Six people were infected with campylobacter linked to raw milk from the Family Cow dairy store in Chambersburg, Pa., including three in Maryland, the state Department of Health and Mental Hygiene said Friday.

    The implicated milk comes in plastic gallon, half gallon and pint containers and is sold directly to consumers on the farm and at drop off points and retail stores in Pennsylvania. It's illegal to sell unpasteurized milk in Maryland, though some consumers have reported getting it anyway at pre-determined drop off points.

    In yet another entry into the we’ve-been-doing-it-this-way-all-our-lives-and-no-one-has-gotten-sick sweepstakes, Edwin Shank, a fourth generation owner of the Family Cow farm told the Baltimore Sun he's never heard of a customer becoming sick from his milk, and no one on the farm has been sickened; through five generations his family has been drinking raw milk from their cows "for 100 years."

    “We're disappointed that this is being made to look definite when, one, the testing hasn't been completed, and two, the test they did do came from an open jug of milk in one family's refrigerator.”

    Shank said that he has a good relationship with the health department and wants customers to know that he disinfects his pipes after every milking and sends samples of milk for testing six times as often as is legally required. He's been selling organic milk for six years and added raw milk three years ago because of strong demand.

    Just cook it doesn’t cut it.

    Especially when 10 per cent of 42 samples of packaging on chicken is contaminated with campylobacter on the outside.

    (And another reason to wrap any poultry in extra plastic, especially if placing into a reusable bag.)

    The Royal Environmental Health Institute of Scotland and other groups said the study confirmed the results of a previous survey by the group that also showed that approximately 10% of samples were contaminated.

    The Chairman of the West of Scotland Food Liaison Group (WOSFLG), Mr Leslie Paton said, “We know that it is fairly common to find Campylobacter in raw chicken but we were quite concerned about the extent to which the external surfaces of the packaging were also contaminated. There are implications for anyone handling such packaging and consumers should take care as there is a possibility of cross contamination to other surfaces and foods.”

    The U.S. Centers for Disease Control reports that on June 29, 2011, the Wyoming Department of Health was notified of two laboratory-confirmed cases of Campylobacter jejuni enteritis among persons working at a local sheep ranch.

    During June, two men had reported onset of symptoms compatible with campylobacteriosis. Both patients had diarrhea, and one also had abdominal cramps, fever, nausea, and vomiting. One patient was hospitalized for 1 day. Both patients recovered without sequelae. During June, both patients had participated in a multiday event to castrate and dock tails of 1,600 lambs. Both men reported having used their teeth to castrate some of the lambs. Among the 12 persons who participated in the event, the patients are the only two known to have used their teeth to castrate lambs. During the multiday event, a few lambs reportedly had a mild diarrheal illness. Neither patient with laboratory-confirmed illness reported consumption of poultry or unpasteurized dairy products, which are common sources of exposure to C. jejuni. The patients resided in separate houses and did not share food or water; none of their contacts became ill.

    Both patients provided stool specimens for laboratory testing; C. jejuni was isolated from each. The pulsed-field gel electrophoresis (PFGE) patterns of the isolates were indistinguishable when restricted separately by two enzymes, SmaI and KpnI. This PFGE pattern had never been reported among 667 specimens from which C. jejuni was isolated in Wyoming and is rare in CDC's PulseNet*database, with a frequency of 0.09% (8 of 8,817). The low frequency of this PFGE pattern suggests that both patients were infected from a common source.

    Animals at the ranch included sheep, cattle, horses, cats, and dogs; none were ill during the site visit on October 19 when investigators obtained fecal samples from five lambs. C. jejuni was isolated from two lambs; one isolate had a PFGE pattern indistinguishable from the two human isolates. C. jejuni is transmitted via the fecal-oral route; this is the first reported association of C. jejuni infection with exposure during castration of lambs. The PFGE pattern identified in these cases had not been associated with animal exposure. Ranch owners and employees were advised to use standardized, age-specific techniques for lamb castration (e.g., Burdizzo, rubber rings, or surgery) and to wash their hands thoroughly after contact with animals.

    Campylobacter is usually number 1 or 2 when it comes to causes of foodborne illness, so I’m having trouble with the lede from the BBC that claims over 90 per cent of cases of campy in the U.K. this year were due to people eating undercooked chicken liver pate, often at weddings.

    The Daily Mirror specifies that 90 per cent of outbreaks of campylobacter at catering venues in 2011 were linked to people eating chicken pate.

    I have no idea what the U.K. Health Protection Agency (HPA) actually said because there is nothing on their website yet, although they apparently analyzed 18 outbreaks of campylobacter in 2011 across England.

    In all, 443 people became unwell and one had to be hospitalised.

    The Food Standards Agency (FSA) has reminded caterers to cook poultry livers to prevent infection.

    Of the 18 outbreaks, 14 occurred in catering venues, and 13 of these were linked to chicken or duck liver pate.

    Seven were linked to wedding receptions at hotels, banqueting venues or public houses and six were associated with catering at other functions such as hotels, clubs and restaurants.

    The HPA found that livers used to make the parfait or pate were undercooked allowing the liver to remain pink in the center.

    The FSA issued updated advice to caterers on the safe handling and cooking of livers twice in 2010, but campylobacter outbreaks associated with the consumption of chicken liver pate have continued to occur.

    Last week, some 80 patrons nibbling on hors d’oeuvres during a fundraiser at the fancy Lowry Hotel in Manchester were sickened with campylobacter linked to the chicken pate.

    Maybe FSA should try different messages using different media, and perhaps evaluate if any of their advisories actually result in fewer sick people.

    PS: The Food Standards Agency subsequently published a statement that says:

    New figures from the Health Protection Agency (HPA) reveal that 90% of campylobacter outbreaks at catering venues were linked to undercooked chicken liver pate. Campylobacter is the most common cause of food poisoning in the UK.”

    Nice reporting BBC (state-sponsored jazz and bad pop music).

     Who knew Manchester, U.K., had such fancy hotels?

    Diners at Salford's luxury Lowry Hotel reported fever, dizziness and vomiting after attending a fundraiser at what has been dubbed Manchester's most fashionable hotel.

    The outbreak is being linked to chicken pate served at a charity dinner and is now being investigated by the Health Protection Agency (HPA) and officers from Salford council.

    The five-star facility gets zero stars for its new addition to the things-not-to-say-after-an-outbreak category: It is the first incident of its kind at the hotel since it opened 10 years ago.

    And be careful when lawyers get sick.

    Solicitor Alex Speed, 44, from Stockport, told how he fell ill after attending the event. “Based on what our table ate, I know that the people who had the tomato soup as a starter didn't get ill. It's reasonable to assume the pate was responsible.”

    He has now launched a compensation claim on behalf of seven clients.

    Dr Rosemary McCann, a consultant with the HPA, said 80 guests had so far reported symptoms - and a number of cases of campylobacter had now been confirmed by laboratory tests.

    Hotel bosses confirmed that the pate dish had been prepared by hotel staff for the dinner on October 8. General manager Peter Kienast said, “We are determined to get to the cause of the issue and the detailed investigation is reviewing every stage of the process from the food source itself to its delivery.”

    'The Lowry Hotel has very stringent procedures and training methods to ensure the highest quality of hygiene in our kitchens.

    GM Kienast, you may want to check out those kitchen procedures.

     Despite some scorching performances by The Who and others at the annual Isle of Wight festival, the island off the southern British coast can now claim host to a campylobacter outbreak that has sickened 30 school kids.

    The source of the outbreak has not been confirmed, but is subject to an ongoing investigation by the Isle of Wight Council and the Health Protection Agency.
