Alberta’s cattle industry sort of recovers a decade after mad cow outbreak

On March 20, 1996, British Health Secretary Stephen Dorrell rose in the House to inform colleagues that scientists had discovered a new variant of Creutzfeldt-Jacob disease (CJD) in 10 victims, and that they could not rule out mad.cows.mother's.milka link with consumption of beef from cattle with bovine spongiform encephalapthy (BSE), also known as mad cow disease.

Overnight, the British beef market collapsed and politicians quickly learned how to enunciate BSE and CJD. Within days, the European Union banned exports of British beef; consumption of beef fell throughout Europe, especially in France and Germany, and in Japan, where suspicion of foreign food runs high. The triumvirate of uncertain science, risk and politics was played out in media headlines.

To refer to the events of 1996 as the BSE crisis is a misnomer, just as scientists are quick to point out that mad cow disease should more appropriately be called sad cow disease or unco-ordinated cow disease.  Rather, the announcement of March 20, 1996 was the culmination of 15 years of mismanagement, political bravado and a gross underestimation of the public’s capacity to deal with risk.  More important than any of the several lessons to be drawn from the BSE fiasco is this: the risk of no-risk messages.  For 10 years the British government and leading scientific advisors insisted there was no risk — or that the risk was so infintesimly small that it could be said there was no risk — of BSE leading to a similar malady in humans, CJD, even in the face of contradictory evidence.  The no-risk message contributed to the devastating economic and social effects on Britons, a nation of madison.men.cowbeefeaters, the slaughter of over 1 million British cattle, and a decrease in global consumption of beef, especially in Japan, at a cost of billions of dollars.

The Canadian Minister of Agriculture was quite adamant there was no risk of BSE developing in Canada.

In July 1996, Dr Norman Willis, Director General, Animal and Plant Health, Agriculture and Agrifood Canada, told the Canadian Veterinary Medical Association’s annual convention that “Actions were taken out of sheer paranoia, with people significantly hyped by the media.  We took actions that went way beyond ones that were scientifically  justified. … We wouldn’t have political interference.  We wouldn’t  have non-science factors influence the actions we took.  BSE blew that all away. … Canada and other trading countries couldn’t hold with science-based  decisions.  There was just too much at stake by way of trade.’’

Canada’s initial dragging to the grown-up’s table of BSE risk management, and apparent lax enforcement of feed regulations for years afterwards led to the inevitable: On May 20, 2003, Canada announced its first home-grown case of BSE.

The eight-year old cow from Alberta had been condemned at slaughter, was sent for rendering and did not enter the food chain.

The first few chapters of the story about the discovery of BSE in Canada were positive.

BSE was bound to show up eventually and the surveillance system set up in 1992 sorta worked. The inspector who pulled a sickly looking eight-year-old cow from the slaughter line prevented it from entering the food chain.

The line in Canada was, this is not the UK, and I was on TV at 5 a.m. the next morning, saying the U.K., had some 186,000 cattle test positive and millions preemptively slaughtered. The significant question was, will Canadian numbers of BSE-positives remain in the dozens or the tens-of-thousands (or something like that).

And yes, producers, processors and government should have been fully aware of the risk rather than act stunned when it happened.

Ten years on, with the perspective that time often offers, my statements seem accurate but naïve.

Canada has since reported 18 cases of BSE, and, just like other aspects of food safety, those in charge talk a good line, but do they know what really bbq_bse_cross_contaminationhappens on farms (or anywhere) day-in, day-out.

And are they interested? Because being interested costs money.

Ian Gray of the Edmonton Journal wrote a 10-year-retrospective piece on the first homegrown BSE case today, beginning with:

In January 2003, Marwyn Peaster’s cow fell down.

The six-year-old Black Angus was one of a small herd Peaster had bought the year before for his grain farm and feedlot near Wanham, in Alberta’s Peace Country.

Believing the cow had pneumonia, Peaster made the fateful decision to send it to a local abattoir instead of calling for a veterinarian or disposing of it on his own property. The vet at the slaughterhouse went by the book and condemned the “downer” cow, so there’d be no chance it could be used for human consumption.

The carcass then went to a rendering plant, but the head was sent to a provincial laboratory in Edmonton for testing. As there was no perceived urgency, there it sat, until May 16, 2003.

Three and a half months after it was shipped, the head was finally tested at the provincial lab and, to the disbelief and horror of everyone involved, registered positive for BSE. The results were confirmed by federal and international laboratories and were announced to the public on May 20.

As of May 1, 2013, vCJD had killed 237 people worldwide.

The attack on Peaster  reached its peak that September with the now infamous remark by then-premier Ralph Klein that “any self-respecting rancher would have shot, shovelled and shut up, but he (Peaster) didn’t do that.”

Peaster has since moved back to the U.S. and is living in the farming community of Ontario, Oregon, where he has a small trucking company. True to form, he has no desire to comment on the 10th anniversary of the discovery of BSE in Canada, in which he was a key, if unwilling, player.

Mad cow no longer dominates the food safety headlines, and that’s good. The potential is always there, and requires good risk management, but a lot more people get sick from lots of other things associated with beef (although vCJD is a terrible way to die).

As the elementary school year wound down in June, 2003, in Ontario, Canada, 
the school three of my four daughters attended had a barbeque for students, staff 
and parents. 
The earlier discovery of Canada’s first domestic case of bovine spongiform 
encephalopathy which received 
extensive media coverage, was of concern to some parents and school
 officials, so a note was sent home to parents, assuring them that the
 hamburgers and hot dogs to be consumed came from a supplier of so-called
 natural, beef and was therefore safe from BSE.

At this particular BBQ, several of the well-meaning volunteer cooks were
 observed to handle the raw, natural hamburger patties with tongs that were
 then used to place re-heated wieners into hot dog buns, possibly
 cross-contaminating the wieners with any number of pathogenic microorganisms
HappyCow[1]such as E. coli O157:H7, salmonella or listeria, and subsequently served to
 parents and children.

About the same time, a bunch of industry folks hosted a BBQ on Parliament Hill in Ottawa, to demonstrate the safety of Canadian beef to politicos.

I watched the servers cook burgers, not use thermometers, and cross-contaminate everything in sight.

I asked, where is the hamburger form?

Don’t worry, it’s not from Alberta, no mad cow here.

Are these pre-cooked?

Nah, they’ve been sitting in the (non-refrigerated) truck for a few hours.

I always wondered if anyone got sick after that feast.

13 sick; Cryptosporidium in Irish water supply again

Contaminated water has left 13 people with stomach illnesses after two outbreaks of cryptosporidiosis.

The Sun says up to 6,000 people in Roscommon town and its surrounds have south.park.diarrheabeen affected by the bug in the local water supply.

A “boil water notice” has been in place since April 25.

People living and working in the area have been advised by Roscommon County Council and the HSE to boil all water for drinking, preparation of salads and for use in brushing teeth.

Both bodies have set up an Incident Response Team to minimize the risk to the public.

Sales of bottled water have shot up in the area amid concerns that the boil water restriction could remain in place until the system gets the all-clear, which could take several weeks.

Roscommon County Council confirmed three dead calves were removed from a stream which is a tributary of one of the sources for the Roscommon town central water scheme where cryptosporidiosis has been detected.

The townlands affected are Killaraght, Rockingham, Knockvicar, Cootehall, Tarmon Road, Kiltycreighton, Crossna, Derrycashel, Moigh, Carigeenroe, Battlebridge and Ardcarne.

Why babies shouldn’t suck on honey

Maybe this is why few read the Atlantic anymore: because they keep reinventing stuff as news when it’s not.

This time, it’s the risk of infant botulism, and why children under 1-years-old shouldn’t eat honey.

According to James Hamblin of The Atlanticaround 10 percent of honey in the U.S. contains spores from the bacteria Clostridium botulinum. That’s not really a honeyproblem for big humans because it’s just the spores, not the botulinum toxin. In infants (humans less than 13 months old), though, those spores can turn into botulinum toxin in their intestines.

Infant botulism can mean anything from subtle changes in muscle tone to so-called “floppy baby syndrome” to “sudden, unexpected death.” None of this is common, but it’s been repeatedly documented and established that infant botulism from honey does happen. It’s not common for kids to get eaten by alligators, either, but that doesn’t mean you let your baby live with an alligator family. Unless you do. (that would be the witty Atlantic version of grabbing the reader’s attention).

A study last week in the journal Pediatrics found that of 397 parents of infants in the Houston area, 11 percent reported using honey-pacifiers with their infants. That means buying pacifiers that contain honey, which are still sold. Some actually contain corn syrup instead of honey — even if they’re still sold as “honey pacifiers” but that too can contain botulinum spores.

Most of the parents (81 percent) at the clinic where this study took place were Hispanic, most indigent and of Mexican descent. The parents said they use the honey pacifiers either out of tradition, because the infants seem to prefer them, and/or because they felt there were health benefits (e.g., “helps with constipation or colic”).

Groundhog Day, Alaska Campylobacter-in-raw-milk version

Folks in Alaska must be undergoing their own kind of public health Groundhog Day – where the same day is relived with slight variations.

But unlike the Bill Murray movie, no matter how much the health types cajole, persuade, and act nice, things won’t change.

Ask Hugh Pennington.

Just days after a report implicated raw milk as the cause of 31 cases of campylobacteriosis, including four cases of reactive arthritis, in early 2013, bill.murray.groundhog.day_.storyAlaskan health profesionals had a paper published in the Journal of Food Protection documenting a 2011 outbreak of Campylobacter linked to … raw milk.

Snappy title, though: Sharing milk but not messages: Campylobacteriosis associated with consumption of raw milk from a cow-share program in Alaska, 2011.

Abstract below.

Alaska public and environmental health authorities investigated a cluster of campylobacteriosis cases among people who had consumed raw, unpasteurized milk obtained from a cow-share program in Alaska. Although raw milk is not permitted by law to be offered commercially, consumers can enter into cow-share agreements whereby they contribute funds for the upkeep of cows and in turn receive a share of the milk for their personal use. Laboratory testing of stool specimens collected from ill persons and from cows on the farm revealed an indistinguishable strain of Campylobacter. In this outbreak, numerous confirmed and suspected cases were not among cow shareholders; therefore, these individuals had not been advised of the potential health hazards associated with consumption of raw milk nor were they informed of the outbreak developments.

6 sick; farm owner denies link to Cryptosporidium outbreak

Five visitors to Cotswold Farm Park and one member of staff are being treated for cryptosporidiosis in the UK.

The farm is run by Countryfile TV host Adam Henson.

Dr David Hunt, consultant for health protection in Public Health England (PHE) Avon, Gloucestershire and Wiltshire told the Wilts and Gloucestershire Standard, “Most of the cases became unwell in April and appear to have visited the park in Adam-henson_280_1307003athe Easter holidays. “The park has co-operated fully with the investigation and has put in place a number of extra measures ahead of the upcoming bank holiday to reduce the risk to future visitors.

Today, host Henson issued a statement on the Cotswold Farm Park website, saying, “It’s been incorrectly reported in some media that cases of cryptosporidium have been linked with us.”

The statement also reads, “There is currently no scientific evidence to confirm that these alleged cases, which occurred over four weeks ago, are linked to Cotswold Farm Park.

“However, we do take public health very seriously so have been proactively liaising with the HSE (Health and Safety Executive) and the local Environmental Health department, to investigate a possibility that these cases may be linked.

“Following a site visit with a HSE inspector and an Environmental health officer it was agreed that Cotswold Farm Park follows best practice procedures in our animal contact areas and we have a proactive approach to educating and informing our staff and visitors of the importance of hand washing.

“We would like to reassure our visitors that we are fully compliant with the industry code of practice for avoiding ill health from farm visits and that there is no reason to avoid contact with animals as long as the correct hand washing procedures are followed.”

Given the number of petting zoo outbreaks, adhering to an industry code of practice and bragging about it is far from convincing.

And handwashing is never enough.

But, the health types will continue with their work, and the story will unfold.

31 sick, 4 develop reactive arthritis; Campylobacter from raw milk, Alaska, Jan–Feb 2013

As noted in that World Health Organization report, the major sequelae of Campylobacteriosis are Guillain-Barré syndrome (GBS), reactive arthritis (ReA) and irritable bowel syndrome (IBS).

GBS is a severe disease, requiring intensive care in some 20% of cases; case-fatality rates in high-income countries are between 3 and 10%. Globally, santa.barf.sprout.raw.milkapproximately one-third of GBS cases have been attributed to Campylobacter infection.

While it is difficult to determine the true extent of ReA, because of a lack of clear diagnostic and classification criteria, studies suggest that it occurs in 1–5% of those infected with Campylobacter. It has been estimated that 25% of ReA cases may go on to chronic spondyloarthropathy.

That’s exactly what happened in the Campylobacter-from-raw-milk outbreak in Alaska earlier this year.

On February 13, 2013, Alaska State Public Health Laboratory (ASPHL) notified the Alaska Section of Epidemiology (SOE) of a cluster of four C. coli isolates with an indistinguishable pulsed-field gel electrophoresis (PFGE) pattern that was new to Alaska. All four isolates were grown from stool specimens collected in late January from ill Kenai Peninsula residents.

Patient interviews and other investigative work indicated that all four of the ill persons with PFGE-matching C. coli strains reported consuming raw (unpasteurized) milk within a few days of their illness onset. These initial interviews also led to additional case finding, primarily by way of ill persons reporting others they knew who were also ill with similar symptoms. While some of the persons napoleon milkwho were initially identified during this investigation were reluctant to say where their raw milk came from, four individuals reported that it came from Farm A, a cow-share farm on the Kenai Peninsula.

A confirmed case was defined as a laboratory-confirmed, PFGE-matched, C. coli infection diagnosed from January 1, 2013 onward. A clinical case was defined as an acute GI illness with self-reported diarrhea lasting ≥2 days in a person with exposure to Farm A raw milk within 10 days of illness onset. A secondary case was defined as an acute GI illness lasting ≥2 days in a person with close contact to a confirmed or clinical case within 10 days of illness onset.

On February 14, SOE notified the Office of the State Veterinarian (OSV) of the outbreak, and a joint press release and health advisory were issued on February 15.2 OSV immediately notified Farm A of the outbreak and requested a list of all active shareholders. Despite notification of the outbreak, Farm A continued to distribute raw milk to shareholders living in the Kenai Peninsula and in Anchorage.

During the week of February 18, two additional confirmed cases were reported—one of which was in a school-aged child who was hospitalized for 4 days with fevers, abdominal pain, rash, and acute reactive arthritis involving the wrists, ankles, knees, and hips. On February 22, an updated health advisory describing new developments in the outbreak was issued.3 On February 22, Farm A provided SOE with an incomplete shareholder list, which lacked contact information for the majority of shareholders. Calls were made to notify persons on the list about the outbreak and to identify additional cases.

In total, 31 cases were identified during the investigation. Ill persons ranged in age from 7 months to 72 years (median: 10 years). Three children and one adult developed reactive arthritis lasting a minimum of 6 weeks. Two persons were colbert.raw.milkhospitalized. All ill persons were Kenai Peninsula residents who either personally consumed Farm A raw milk within 10 days of illness onset (n=29) or met the secondary case definition (n=2).

Environmental Investigation

On February 22, OSV and SOE toured Farm A and collected cow feces, milk, and other environmental samples. Steps where the milk could be contaminated (from collection to bottling) were reviewed with the farmer, and the inherent risk of bacterial contamination of unpasteurized milk was discussed. The outbreak strain of C. coli was not isolated from the samples collected at the farm that day; however, three different strains of C. jejuni were isolated from cow manure, and Listeria monocytogenes grew from a raw milk sample.

This large outbreak of C. coli infection on the Kenai Peninsula was caused by consumption of Farm A raw milk. While this outbreak appears to be over, additional campylobacteriosis cases could still be identified at any time as Campylobacter species were identified from Farm A manure during the environmental investigation. Furthermore, this is the second outbreak of campylobacteriosis associated with consumption of raw milk distributed by an Alaskan cow-share operation in the past 2 years. These outbreaks are an unfortunate reminder of the inherent risks associated with raw milk consumption, and underscore the importance of pasteurization.

It is not surprising that the C. coli outbreak strain was not isolated from the environmental samples, as Campylobacter bacteria are difficult to isolate from the environment, they are shed intermittently in cow manure, and the farm visit occurred weeks after the outbreak peaked. Incidentally, L. monocytogenes—a bacteria that can cause life-threatening meningitis—was isolated from Farm A milk; no listeriosis cases were reported during the outbreak.

Finally, four (13%) ill persons developed reactive arthritis, a painful form of inflammatory arthritis that sometimes occurs in reaction to a bacterial infection and can persist for up to 12 months. These cases underscore the fact that Campylobacter infection can lead to prolonged adverse health consequences.

WHO: the global view of Campylobacteriosis

From July 9-11, 2012, the World Health Organization (WHO), in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the World Organisation for Animal Health (OIE), convened an Expert Consultation on The Global View of Campylobacteriosis, in Utrecht, Netherlands.

Below are the general conclusions:

 Considerable new evidence, data, and analytical tools have emerged in the ten chicken.campy.vaccineyears since the previous WHO consultations on Campylobacter.

 In terms of public health actions, there is already a sufficient evidence base to address the burden of disease from C. jejuni and C. coli. The importance of other species in terms of burden of disease is still unclear, but is considered unlikely to eclipse these two species.

 Public health surveillance can provide important basic information to policy-makers about the frequency of infection, who is affected, and the success of specific prevention strategies. Surveillance is the starting point for studies of burden of disease and source attribution.

 There is a need for standardization and validation of laboratory methods.

 Burden of disease studies provide the evidence base that drives the need for control measures across all outcomes of Campylobacteriosis while taking into consideration its underestimation.

 There is considerable potential for the identification of new sequelae from acute infection. However, decision criteria are needed on the level of evidence required to add outcomes to burden estimates. This applies to all sequelae, and may increase burden estimates considerably.

 In order to reduce exposure countries should be encouraged to adopt the recently developed Codex Guidelines for the Control of Campylobacter and Salmonella in chicken meat which promote a risk based approach to the management of Campylobacter in chicken meat traded internationally. campy.who.jul.12Consideration should be given to the development of additional guidance and recommendations for the management of Campylobacter in other potential food vehicles that are traded internationally.

 Source attribution studies should adopt a holistic attitude, considering multiple sources and pathways of exposure. Where possible attribution estimates should combine both molecular tying and epidemiological data and include measures of uncertainty.

 Although poultry is the dominant source of infection in many countries, controlling Campylobacter in poultry meat will not completely eliminate the disease in humans. Options are available to control other pathways which are based on general hygiene, generic control measures including biosecurity and sanitation.

 Reducing the load of Campylobacter in poultry to a level with a low probability of causing illness is unlikely to be achieved by any single pre-harvest or post-harvest intervention. Success will most likely occur through use of multiple stepwise interventions to lower the load of Campylobacter on or in each bird on the farm and in the processing facility.

 The epidemiology of Campylobacteriosis is likely to be different in high-income countries versus LMIC. This will affect control options.

 GFN, as an international training and capacity development network, will play a key role in promoting better and more consistent methodologies and quality assurance for work with Campylobacter. Where possible, GFN should link with other international networks, such as FERG, which is promoting capacity development in estimation of burden of foodborne disease.

Raw milk sickened scores despite inspections

The majority of those sickened in raw milk outbreaks is children under 10-years-old. And there’s good immunological reasons for that. If adults want to take the risk with raw milk, they will, just like with cigarettes and alcohol. But parents generally don’t have a scotch and smoke with their 4-year-olds.

That’s what I told Karen Rowan of My Health News Daily in her report about a report appearing in Clinical Infectious Diseases, summarizing a Jan. 2012 campylobacter outbreak linked to raw milk that sickened 148 people in four states.

The dairy that sold the milk had a permit for selling unpasteurized milk, and had passed all inspections. The farm was among the largest sellers of unpasteurized colbert.raw.milkmilk in the state.

The dairy also tested its own milk for E. coli bacteria more often than was required. The vast majority of the sick people drank the milk before its “best by” date.

The only deficiencies that investigators found were that a mechanical milk bottle capper was broken, so employees had capped the bottles by hand, and that the water used to clean equipment was cooler than recommended (110 to 120 degrees Fahrenheit, instead of 160 to 170 degrees F).

But these issues were “minimal,” and this campylobacter outbreak demonstrates “the ongoing hazards of unpasteurized dairy products.”

Douglas Powell, a professor of food safety at Kansas State University advises that raw milk not be given to children. “As adults, you’re free to choose. But don’t give it to your kids.”

The people sickened in the outbreak ranged in age from 2 to 74, the report said. Typically, campylobacter infections cause diarrhea, abdominal pain and fever that last about a week, and most people get better on their own. In the outbreak, 10 people were hospitalized.

The dairy immediately suspended unpasteurized milk sales when it was informed of the outbreak.

The researchers recommended that state officials consider more regulation of unpasteurized milk, such as monthly pathogen testing.

20 sick: Kansas Mexican restaurant closed after food poisoning; S. aureus suspected

An East Topeka Mexican restaurant and meat market has been forced to temporary close after more than 20 people reportedly became sick after eating its food.

Carniceria Camecuaro, 1016 S.E. 6th, has been closed since Sunday after the Kansas Department of Agriculture advised it to shut down.

Manager Carmen Jaramillo confirmed the restaurant was closed Carniceria CamecuaroTuesday.

“We have done business for seven years. This is the first time we have this kind of problem when some persons became sick from the food,” she said.

Carniceria Camecuaro will remain closed while KDA conducts follow-up inspections and directs potentially contaminated food to be thrown out. The staff also has to undergo further training regarding food safety codes. Depending on how that goes, the establishment could be open within the week, said Charlie Hunt, epidemiologist with the Kansas Department of Health and Environment.

KDA and KDHE, which handles food-borne illness outbreaks, were advised of the issue Sunday when a local hospital reported at least four people suffering from food poisoning after eating at the restaurant, Hunt said.

Additional complaints have come in, he said, estimating that more than 20 people were affected by the restaurant’s food. Based on interviews, he said, the culprit looks to be the pork carnitas.

Although the investigation continues, the current hypothesis was that the food-borne illness was caused by a bacterium known as staphylococcus aureus, Hunt said.

Revisiting high school: when you dance, I can really love

The Springfield Academy in Calne, U.K., will reopen tomorrow after closing due to an outbreak of sickness and diarrhea among staff and pupils.

The school closed on Friday after 12 pupils living at boarding house for students on the site caught a sickness bug lasting between 24 to 34 hours.

Headteacher Trystan Williams said all the school’s residential houses had been deep cleaned by specialist agencies in order to make sure pupils could return safely.

The Brits have a thing about separating themselves from their teenagers, and suppressing their WASP feelings. I’ve been talking a lot with my older daughters of late and it’s been incredibly gratifying.

To all the Susie Bakers out there (my high school sweetheart, Chapman married his, I’m thrilled with what I have now) this note’s for you. Sue introduced me to Neil. She also introduced me to Harry Chapin and Cat Stevens, which didn’t go over so well.
