Eurosurveillance reports today on a March 2008 outbreak of Salmonella Muenster in 25 laboratory confirmed cases in France.

Four patients were admitted to hospital. … S. Muenster was isolated from both cases and the incriminated goat’s cheese. …

The place of purchase of the goat’s cheese was known for 10 cases: Seven cases had purchased unpasteurised goat’s cheese at an agriculture exhibition that was held in Paris from 23 February until 2 March, and three cases had purchased this type of cheese at a local market in south-eastern France….  During the same period, a household cluster of salmonellosis involving three cases was reported through the mandatory notification system. The investigation of this cluster incriminated unpasteurised goat’s cheese (consumed on 8 February 2008) as the source of infection. The isolates of these cases were later shown to be positive for S. Muenster.
 

Listeria-laden cheese hospitalized 38, killed 15 in Quebec last fall; producers want compensation

Here is what is lost in the gushing about raw-milk cheeses and many other forms of food pornography:

The fall 2008 outbreak of listeria in cheese in Quebec led to 38 hospitalizations, of which 13 were pregnant and gave birth prematurely. Two adults died and there were 13 perinatal deaths.

But, the discussion in Montreal over the past two days is about the fate of small cheese producers, who are apparently giving up.

Ever since last year’s listeriosis outbreak, when provincial inspectors seized tonnes of Quebec cheeses believed to have been cross-contaminated by the listeria bacterium, Fromagerie Lehmann and other raw-milk cheese producers were visited constantly by officials on the lookout for the listeria bacterium.

Like 20 or so others, Lehmann finally gave up on raw-milk cheese altogether.

By some estimates, only 10 Quebec raw-milk cheeses remain. The others now are made with milk that’s been heated to kill unwanted bacteria – and, some say, the flavours of the meadow and the changing seasons.

On Monday, the provincial ombudsman concluded the Quebec government was ill-prepared to handle the outbreak of listeria contamination in some cheese products last summer, but it was right to order a mass recall of the cheeses.

Parking lot cheese sickens three in Illinois

Don’t buy cheese in a parking lot.

That should probably apply to raw seafood as well.

Winnebago County Health Department Administrator J. Maichle Bacon said at least three people have been sickened and four more cases are being investigated after buying cheese from parking lot vendors.

The Rockford Register Star reports that samples of the cheese are still being tested at the Illinois Department of Public Health laboratory in Springfield, but had been found positive for fecal coliform and Listeria.

The three confirmed cases were positive for the bacteria Campylobacter jejuni. Bacon said,

 “This, of course, is a product that would never be approved for sale.”
 

67 sick from raw milk cheese in Kansas

For all the fawning media coverage and energy expended, I figured there would be millions of Americans drinking raw milk.

A story in the Dayton Daily News pegs the number at 500,000.

That’s nothing when it comes to food dollars. And there are reasons why the numbers are so low. As the U.S. Centers for Disease Control reported in its Morbidity and Mortality Weekly Report today,

“On October 26, 2007, a family health clinic nurse informed the Kansas Department of Health and Environment (KDHE) that Campylobacter jejuni had been isolated from two ill persons from different families who were members of a closed community in a rural Kansas county. By October 29, 17 additional members of the community had reported gastrointestinal illness and visited the clinic within a week. All 19 persons reported consuming fresh cheese on October 20 that was made the same day at a community fair from unpasteurized milk obtained from a local dairy.

"This report summarizes the findings of an investigation by KDHE and the local health department to determine the source and extent of the outbreak. Eating fresh cheese at the fair was the only exposure associated with illness (relative risk [RR] = 13.9). Of 101 persons who ate the cheese, 67 (66%) became ill. C. jejuni isolates from two ill persons had indistinguishable pulsed-field gel electrophoresis (PFGE) patterns, and the isolate from a third ill person was nearly identical to the other two. Although all samples of cheese tested negative for Campylobacter, results of the epidemiologic investigation found an association between illness and consumption of fresh cheese made from unpasteurized milk. To minimize the risk for illness associated with milkborne pathogens, unpasteurized milk and milk products should not be consumed."
 

Quebec cheese linked to two deaths, one miscarriage, 120 illnesses — gets government bailout

I was a fan of Quebec agriculture minister Laurent Lessard.

After two separate outbreaks  — one listeria, one salmonella – in Quebec-made cheese that killed two, caused one miscarriage, sickened six other pregnant women and their newborn babies, and sickened a total of about 120 people, Lessard ordered a crackdown.

When asked about compensation for cheese retailers who had to discard potentially contaminated product, Lessard said on Sept. 17,

"The province is not there to compensate. We aren’t an insurance company."

Retailers have a responsibility to market safe products, and if there’s a risk associated to what they’re selling they have to absorb the losses, he said.

But being astute about Quebec politics and the role of dairy producers, Lessard didn’t rule out possible compensation for cheese producers, even though provincial food inspectors found traces listeria in 16 different establishments, either on cheese or processing equipment.

Three weeks later, and it appears that politics has caught up with the public health overtures of Monsieur Lessard as he announced Friday that Quebec’s small cheese producers and retailers will receive a three-year, $8.4-million provincial aid package, along with $11.3-million in interest-free loans.

"I want to reassure Quebec consumers. All of Quebec’s cheese producers are presently offering safe and secure products.”

Approximately half of the aid package will be spent on improving quality control. Government inspections will be conducted monthly, the minister said, and retailers will receive guidelines on improving the handling of cheeses.

Producers and retailers reported a significant drop in sales of Quebec cheeses, which last year alone totaled $2.6-billion.

Where’s the compensation for the sick people? Where’s the effort to accurately present the risks of soft cheeses (oh, and deli meats) to certain populations, like pregnant women and the elderly.

I’m not such a fan anymore.

Pregnant woman miscarries because of listeria in Quebec cheese

Public health officials in Quebec say a pregnant woman in the province has lost her baby, possibly because of listeriosis.

Officials are still awaiting test results to confirm whether the woman who lost her baby was infected with the bacteria, said Dr. Horatio Arruda, Quebec’s director of public health protection.

She didn’t lose the baby. It’s not like she misplaced the baby somewhere. The baby died because of listeria. Pregnant women should not eat a whole bunch of refrigerated ready-to-eat foods, but in the rush to promote raw milk cheese and food porn, those in charge forgot to remind those who are vulnerable of the risks.

Max Dubois, the owner of L’Échoppe des Fromages in St. Lambert, wants to know who will compensate him for the $40,000 worth of cheese inspectors seized and destroyed from his store on Saturday.

"Why could they not have organized a voluntary recall, as they do in France. Each cheese would have been sent away for analysis. We would have better been able to trace the spread of the bacteria. But now all the evidence has been destroyed. We’ll never know if it was spread through a distributor, or on the paper it was wrapped in, or in some other way."

Uh, France is no better. Here is the latest French cheese recall due to listeria.

Microbiologist Jacques Goulet, a cheese specialist in the food science department at Université Laval, says he, too, believes the government over-reacted.

"Listeria is present everywhere. But for most people, the risk posed by listeriosis is very low. Healthy people are rarely affected by the bacteria," he said, noting that the annual average of listeriosis cases in Quebec is about 50. (The public health department reported 63 cases in 2007 and 49 in 2006.).

Way to cite statistics. The people who got sick are real people who thought they were eating safe food.
 

Listeria in cheese from Toronto shop sickened pregnant woman

On Aug. 29, 2008, Ping Chiu, owner of Cheese Magic in Kensington Market, had to throw out $1,000 worth of cheese and wasn’t happy about it.

"According to the health inspector, it was listeria. Although I was told by two big cheese suppliers that it can’t be listeria."

It was listeria.

“Health officials confirmed Tuesday that product sold at a popular Kensington Market cheese shop was the source of the listeria bacterium that sickened a pregnant customer.

“Cheese Magic at 182 Baldwin St. was closed down last week after a regular customer fell ill after contracting listeriosis. Health inspectors also claim they found cat and mouse droppings in a food area of the store, mould growth inside a walk-in cooler, and products stored at incorrect temperatures.

“The business has since reopened after inspectors found it had met all safety requirements when they revisited the shop.”

For some bizarre reason, Dr. Barbara Yaffe, an Associate Medical Officer of Health for Toronto Public Health, felt it necessary to downplay the risk of listeria, especially for pregnant women, rather than shout it from the rooftops.

“Keep in mind that the risk from listeriosis is low for healthy individuals. Those most at risk of developing serious illness are pregnant women, the elderly, and those with weak immune systems."

Thanks. My pregnant wife will keep that in mind. So will the pregnant woman who got sick. At some point Canadian health types will have an honest discussion with consumers at risk without worrying if they will offend industry.
 

Food safety in pregnancy is not simple

Yesterday I enjoyed an aperitif at Houlihan’s with my friend Angélique. Although the conversation was excellent, ordering was complicated for me. I wasn’t supposed to eat at least half of the items offered, and another third of them didn’t sound good to me.

Pregnancy food safety guidelines combined with changing tastes and sensitivity to smells make ordering very difficult. On our trip home from Australia on Sunday, for example, I wanted to grab a sandwich at LAX, and because we were at a deli, that left only one choice for me: a chicken Panini. Everything else had unheated deli meat – known to put me at risk for listeria.

At Houlihan’s, I used to enjoy the tuna wontons, but the tuna is only seared and I don’t trust raw fish right now. I couldn’t eat the very appetizing brie starter because the waitress didn’t think it was heated, and the bruschetta that we did share was a big question mark for me. It had goat’s cheese together with the tomato mix. We now know that tomatoes are all supposedly safe from Salmonella, but how safe was the cheese? I take at least a little comfort in knowing that I’ve been fully vaccinated against Hepatitis A thanks to my past wild travels. Angélique and I also shared a spinach and artichoke dip that came with fresh cilantro and scallions sprinkled all over the chips. I grow my own cilantro at home and know how hard it is to keep it clean and out of the snails’ reach …

Finally, very hungry, I just ate and tried to ignore the smaller risk factors. I did my best but I still didn’t feel confident that my food was safe. Who knows or can control what was happening in the kitchen?

For those who want to tell me, and every pregnant woman, how simple it is to eat safely during pregnancy, I beg to differ. See “Listeria warning for pregnant women” for example. Dr. Paul McKeown says, “Simple measures such as ensuring that the fridge is in good working order with the temperature between two and five degrees Celsius, eating food that is well within its use-by date so that harmful bugs will not have had time to grow and practising good general food hygiene will reduce the risk of listeriosis.”

We, as consumers, can reduce some of the risks but we cannot eliminate them. And I find that the more I know about food safety, the more complicated all of this becomes. When you’re hungry and the airline offers you a roll with cheddar and pastrami … and you ask your food safety expert partner, “if I pick off the pastrami, is the sandwich safe to eat and how much cross contamination might have taken place?” and he shrugs … sometimes you have to decide for yourself.

What you can and can’t eat when you’re pregnant

At our first prenatal visit, which at 8 weeks seemed very late, we finally got some food safety advice from the medical staff. Along with the typical list of foods to avoid (non-pasteurized cheeses, smoked salmon, etc.), the staff member told us if we do eat cold cuts, it is advisable to get them from the deli counter in the supermarket rather than buying the packaged ones from big companies. We were a bit surprised, as this was … exactly wrong advice. The risk of listeria from the deli section is generally higher because it’s difficult to clean the slicers and we do not know how often they are cleaned.

While Ben and Doug have been going back and forth about which cheeses are safe for me and Dani to eat (is pasteurized brie OK or not? what about blue-veined cheeses?), I realize I cannot eliminate every risk from my diet. I can, however, minimize some of them. I just slice the brie, put it on Doug’s homemade baguettes, and pop it in the toaster. (It’s also delicious with a sliced beet.) The heat serves as a kill-step in case there is a concern. No, I do not use my meat thermometer to check the internal temperature of the soft cheese. I supposed you could if you really are worried, but at that point it’s probably easier to not eat brie.

Although I very much miss smoked salmon — a staple food before pregnancy, I will not eat it unless it has been thoroughly cooked. Yesterday Salmolux Inc recalled 6140 packages of their Wild Alaskan Smoked Salmon Nova Lox because of a possible Listeria monocytogenes contamination. Unfortunately, this kind of recall is common in minimally processed ready-to-eat foods. While no one is reported ill from this possible contamination, the risk is one I’m not willing to take.

Camembert Wars: if this is progress, I’ll take mine pasteurized

The AFP is reporting today that “real” camembert makers can rejoice. In addition to reducing the geographic boundaries of the camembert region, now the only camembert makers that will be recognized with the prestigious AOC (appellation d’origine contrôlée) label will:

–    use only raw milk;
–    have at least half of the cows providing the milk from Normandy origin; and,
–    ensure that their cows graze on Normandy pastures for at least 6 months of the year and fed hay the remainder of the time.

The grazing restrictions are new to the AOC conditions. I find them particularly surprising as research has shown that grass-fed or not, all cows can carry E. coli O157:H7.

The “real camembert” supporters apparently found the decision to be “undeniable progress.” Lactalis and Isigny-Sainte-Mère, two large companies that previously produced more than 80% of AOC Camembert, decided last year to begin heat-treating their milk as a safety measure.

Francophiles, can read today’s original story for themselves. The French clearly articulate that the raw milk camembert has a velvety taste compared to the pasteurized version, but that the traditional methods are more onerous because they require various testing measures to avoid pathogens such as listeria. According to my favorite food safety advisor, you cannot test your way to safe food. The new and improved camembert will have enhanced risks.
