Unpasteurized

  • Posted: January 27th, 2012 - 9:19pm by Doug Powell

    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.

    A major London department store is giving consumers the chance to buy unpasteurised milk, despite the government food watchdog's claim that the move is illegal on public health grounds.

    Raw milk, is banned from mainstream sale in England, Scotland and Wales. Its distribution is so tightly regulated that supermarkets and mainstream retailers are not allowed to stock it, although it can be sold directly by producers.

    But the growing number of raw milk devotees are now able to buy it fresh from a vending machine in Selfridges food hall in London's west end.

    The Food Standards Agency (FSA) said the move was in contravention of food hygiene regulations designed to protect consumer health, and released a statement saying "discussions are still ongoing."

    Raw milk dispensers are hugely popular on the continent, allowing customers to top up their own glass bottles. But the FSA says it may contain bacteria "such as salmonella and E coli that can cause illness."

    It said it had informed Westminster City Council, which deals with the day-to-day enforcement of food safety and public health protection in its area, of the position and that it believed this had been passed on to Selfridges.

    Selfridges said Westminster City Council knew it was selling the milk and claimed it had regulatory approval because the sales will be handled by a concession run by Longleys Farm, an established dairy farm.

    The bottles carry a health warning demanded by the FSA that reads: "This organically produced raw milk has not been heat treated and may therefore contain organisms harmful to health."

    Steve Hook of Longleys Farm, based in Hailsham, East Sussex, said he had been selling raw milk since 2007. "We pay fantastic attention to hygiene to ensure the strict bacteria tests conducted on the milk by the FSA are easily met."

    Both Hook and Selfridges said they were not aware that they were doing anything wrong, and would keep selling the milk until they were officially ordered not to.

    Consumers in Tompkins County, New York and surrounding areas not to consume unpasteurized raw milk produced at Jerry Dell Farm located at 39 Fall Creek Rd (RT 366) in Freeville, due to possible contamination with campylobacter.

    The state Health Department received 2 reports of Campylobacter enteritis, from people who have consumed raw unpasteurized milk purchased from Jerry Dell Farm. Both patients have recovered.

    Anyone who purchased milk from Jerry Dell Farm and still has the product should discard it immediately. Individuals experiencing gastrointestinal illness symptoms after consuming milk purchased from Jerry Dell Farm should contact their health care provider.

    The farm has voluntarily suspended milk sales. The farm was first notified of the reported illnesses on September 22.

    Confirmatory tests completed today at the New York State Food Laboratory found that the raw unpasteurized milk produced at Jerry Dell Farm, and collected on September 22, contained Campylobacter. This producer will be prohibited from selling raw milk until subsequent sampling indicates that the product is free of pathogens.

    A 30-year-old man and his three-year-old niece were diagnosed with salmonella on a family farm in Kildare last year, the Health Protection Surveillance Centre has revealed in a report.

    They both drank unpasteurised -- or raw -- milk produced by cows on the farm before contracting salmonella.

    The warning comes as new legislation is to be introduced in Ireland later this year banning the sale of unpasteurised milk.

    This person sounds like a bad food safety manager.

    New York City’s Village Voice ran a piece about the paperwork being required by health types in the form of HACCP plans (Hazard Analysis Critical Control Point).

    “… the plans require chefs to map out a convoluted strategy for avoiding foodborne pathogens in potentially dangerous cooking techniques…. Sous vide came under scrutiny and was even banned temporarily in 2006 while the health department decided how to regulate the newfangled method. … Now restaurants desiring to use the sous vide method must have an approved HACCP plan to do so.”

    Elizabeth Meltz, director of food safety and sustainability for the Batali Bastianich group, which includes Babbo, Del Posto, and food emporium Eataly, was quoted as saying,

    "There was one E. coli outburst from apple cider, and now there's a HACCP plan required to make it for mass consumption, too."

    Maybe the E. coli outburst Meltz was referring to was in Oct. 1996, when 16-month-old Anna Gimmestad of Denver drank Smoothie juice manufactured by Odwalla Inc. of Half Moon Bay, Calif. She died several weeks later; 64 others became ill in several western U.S. states and British Columbia after drinking the same juices, which contained unpasteurized apple cider --and E. coli O157:H7. Investigators believe that some of the apples used to make the cider may have been insufficiently washed after falling to the ground and coming into contact with deer feces.

    Or maybe the outburst was in Maryland last year when seven people got sick drinking unpasteurized cider; three were hospitalized.

    Maybe the outburst was in Iowa, when eight were stricken with E. coli o157:H7 after drinking unpasteurized cider.

    Maybe it was one of the 31 other outbreaks of illness we’ve document linked to unpasteurized juices – primarily apple cider. The complete table with body count is available at

    An outbreak of E. coli O157:H7 first became public in Nov. 2010, and would eventually sicken at least 38 people in several U.S. states. Investigators believe the source was Dutch Style Gouda Cheese produced by Bravo Farms of Traver, California from raw milk and sold primarily at Costco and Whole Foods Market stores.

    The artisan cheese maker temporarily shut down.

    Bravo was forced to quarantined stockpiles of cheese, and -- no real surprise – of the 24 unpasteurized cheese samples investigators took, 15 tested positive for listeria and one tested positive for E. coli O157:H7.

    According to the L.A. Times today, state and federal investigators found at least 50 live flies flitting around a processing area at Bravo. They also reported that a rabbit hopped out of a storage room, and a dairy worker scratched his chin then handled milled cheese with his bare hands.

    On Thursday, U.S. marshals and Food and Drug Administration agents arrived at the cheesemaker and seized the Gouda, along with piles of Edam and blocks of white cheddar. All told, investigators have locked up more than 80,000 pounds of cheese. Prosecutors say it is all headed for the garbage disposal.

    Worried that the cheese would somehow reach the public, and acting to shift the case from state to federal jurisdiction, the Justice Department used a civil legal mechanism to arrest a product — food — and essentially impound it.

    Prosecutors filed a civil complaint in federal court in Sacramento last week that lists the cheese — not the farmers who made it — as defendants.

    John Sheehan, director of the FDA's dairy division, said the inspections came from concerns "about raw-milk cheese made under artisanal conditions" and a flurry of nine artisan cheese recalls last year. As of October, the FDA had inspected 102 facilities, some big, some small. Of the 147 samples taken, 32 tested positive for listeria. The inspections continue.

    Bravo, which is cooperating with federal officials, has been cleared to make cheese again. It's using pasteurized milk.

    In October, 1996, 16-month-old Anna Gimmestad of Denver drank Smoothie juice manufactured by Odwalla Inc. of Half Moon Bay, Calif. She died several weeks later; 64 others became ill in several western U.S. states and British Columbia after drinking the same juices, which contained unpasteurized apple cider --and E. coli O157:H7. Investigators believe that some of the apples used to make the cider may have been insufficiently washed after falling to the ground and coming into contact with deer feces.

    In the fall of 1998, I accompanied one of my four daughters on a kindergarten trip to the farm. After petting the animals and touring the crops --I questioned the fresh manure on the strawberries --we were assured that all the food produced was natural. We then returned for unpasteurized apple cider. The host served the cider in a coffee urn, heated, so my concern about it being unpasteurized was abated. I asked: "Did you serve the cider heated because you heard about other outbreaks and were concerned about liability?" She responded, "No. The stuff starts to smell when it's a few weeks old and heating removes the smell."

    Yesterday, Baugher's Orchard and Farm in Westminster, Maryland, announced to local fanfare – and some customer distress -- that it will change the way it produces apple cider in the future after E. coli infections were linked to the product this fall.

    Dr. David Blythe, medical epidemiologist from the Department of Health and Mental Hygiene, said environmental and product testing of the apple cider was conducted in November and December in an attempt to confirm a link between seven cases of a specific strain of E. coli infections that began appearing in mid-October that was believed to be associated with the consumption of Baugher's unpasteurized apple cider.

    Three of the seven cases resulted in hospitalization. Five of the seven cases were children younger than 18. All afflicted people recovered and those hospitalized were discharged, Frances Phillips, Deputy Secretary for Public Health from the DHMH said.

    Blythe said the E. coli strain was not found in any of the tested samples, but that they were not able to test from the batch of apple cider that is suspected of causing the sickness.

    Though they cannot make any conclusions from the testing, Blythe said the information collected, like interviews from those affected by the E. coli strain, still points to the apple cider as what made people sick.

    Dwight Baugher, farm manager, said they are not currently making any apple cider. The company typically makes cider from about mid-September through mid-March.

    "There's no way of knowing if we had anything to do with it," he said.

    Though they have not found out the source of the E. coli strain, they are working on changing the apple cider production process to include pasteurization.

    It’s the phrase every food safety type has heard; experienced investigators will convey their disdain with a wry smile, rather than the full eye-rolling and gnashing of rookie teeth: “I’ve been making cheese (substitute your favorite food) this way for 30 years and I’ve never made anyone sick.

    That’s the line Oroville, Washington, farmer Sally Jackson told a state inspector a few weeks ago as preliminary evidence linked Sally’s cheese to an E. coli O157:H7 outbreak.

    The Seattle Times reports this morning that over the past week, Jackson learned that eight cases of E. coli illness are likely linked with her products. On Friday, she announced a recall and is cooperating with government agencies.

    It is the second time in two months that an artisan cheesemaker in Washington was connected with a bacteria that causes foodborne illnesses, though the reaction of the two cheesemakers could not have been more different.

    Inspectors found Listeria monocytogenes in cheese made by the Estrella Family Creamery, and also repeatedly identified the bacteria in swabs of its Montesano facility, yet that Grays Harbor County dairy refused a request to recall its product. In October, the Food and Drug Administration obtained a court order forcing it to shut down. The creamery is battling the court action.

    To her credit, Jackson said, "I do not want to be associated with their fight. The bottom line is, I don't want to make anybody else sick."

    Four cases of E. coli O157 came to the state Health Department's attention in the fall, including the case of one woman who was briefly hospitalized. Laboratory tests confirmed the four were linked to each other. Four additional E. coli cases in Oregon, Minnesota and Vermont also were linked to the Washington outbreak via laboratory tests.

    According to the state Department of Agriculture, one unopened cheese wheel tested positive for E. coli. Investigators are awaiting the results from additional lab tests that will compare the strain of E. coli from the illnesses with that found in the cheese.

    For years, Jackson operated with few problems, however in the last year, inspectors have noted several violations at her facility, including finding that she did not sanitize equipment after use. She has worked to fix the problems.

    She and a part-time helper milk 40 sheep, 12 goats and a cow named Renata. They sell to high-end restaurants, as well as retail stores across the country, and the cheeses are distinctively wrapped in grape leaves from neighbors' farms.

    Over the years, her products have been served in most Seattle fine-dining establishments, including Douglas' Palace Kitchen. Gourmets rave about the quality, so news of the problem and the listeria issue at Estrella came as a shock.

    Get over it. Fancy food doesn’t mean safe food.

    The New York Times reports this morning that listeria can pose special challenges for artisan cheesemakers. Many make their cheese right on the farm, where the bad bacteria are right outside the cheese room door (or inside – dp). And small producers often lack the safety training and resources available at bigger companies.

    For example, Sharon McCool got a shock last year as she prepared to begin selling the first batch of cheese she had made from milk produced at her family’s organic dairy, Rosecrest Farm, in Chehalis, Wash. State inspectors told her the Swiss cheese she had labored over for months was contaminated with listeria.

    Tests showed that the bacteria was contained in a mixture of wine, water and salt, called a smear, that Ms. McCool had been brushing on her cheese each day as it aged. Without knowing it, she was dosing the cheese with listeria.

    Ms. McCool threw out 900 pounds of cheese, changed some of her practices, got rid of the smear and started over.

    Ms. McCool and her husband, Gary, have for years operated a dairy, where sanitation is paramount, so she thought she was well versed in food safety. But she now sees that she had overlooked some obvious pitfalls.

    Before, Ms. McCool said, she had been so proud of her new business that she had often showed visitors around, possibly introducing listeria through their shoes or clothing.

    Now, visitors are kept out. “Pretty much everything is really a whole lot stricter,” Ms. McCool said.

    The number of small-scale, artisan cheesemakers has boomed in recent years but little or no formal training is required. Safety rules and enforcement also vary from state to state.

    Soft cheeses — including brie, mozzarella and queso fresco — are more likely to become contaminated with listeria because they have a relatively high moisture content and low acidity, creating a more hospitable environment for the bacteria. In addition, listeria grows well at low temperatures, so even it can thrive even in a refrigerator.

    The F.D.A. said it is inspecting both raw-milk and pasteurized cheese facilities for listeria, and recalls this year have been for both types of cheeses.

    The agency also said it was reviewing the aging rules in light of evidence that the 60-day period might not be effective.

    The New Mexico Department of Health has confirmed an outbreak strain of E. coli O157:H7 in an intact sample of cheese sold at Costco stores.

    The Alamogordo Daily News and Associated Press say the outbreak strain had been isolated at other laboratories in already opened packages of cheese, but this is the first confirmation from an intact cheese sample.

    The findings confirm what scientists have found in the past: 60-days don’t mean much when the cheese is made from unpasteurized or raw milk (see abstract below; thanks Carl).

    The Bravo Farms Dutch Style Raw Milk Gouda Cheese was offered for sale and for in-store tasting between Oct. 5 and Nov. 1 at Costco stores in Arizona, Colorado, New Mexico, Nevada and the San Diego, Calif., area.

    Health officials say at least 37 people from five states have become sick with E. coli since mid-October. Cases in New Mexico include a 41-year-old man, a 7-year-old girl from Bernalillo County and a 4-year-old boy from Valencia County who are all recovering. Arizona has 19 cases reported, Colorado has 10, California has 3 and Nevada has two. Nationally there have been 15 reported hospitalizations, one case of hemolytic uremic syndrome and no deaths.

    People who have any of the cheese should not eat it. People should return the cheese to the place of purchase or dispose of it in a closed plastic bag placed in a sealed trash can. This will prevent people or animals from eating it.


    Survival of a five-strain cocktail of Escherichia coli O157:H7 during the 60-day aging period of cheddar cheese made from unpasteurized milk

    May 2006

    Journal of Food Protection, Volume 69, Number 5 pp. 990-998(9)

    Schlesser, J.E.; Gerdes, R.; Ravishankar, S.; Madsen, K.; Mowbray, J.; Teo, A.Y.L.

    Abstract:
    The U.S. Food and Drug Administration Standard of Identity for Cheddar cheeses requires pasteurization of the milk, or as an alternative treatment, a minimum 60-day aging at ‰¥2°C for cheeses made from unpasteurized milk, to reduce the number of viable pathogens that may be present to an acceptable risk. The objective of this study was to investigate the adequacy of the 60-day minimum aging to reduce the numbers of viable pathogens and evaluate milk subpasteurization heat treatment as a process to improve the safety of Cheddar cheeses made from unpasteurized milk. Cheddar cheese was made from unpasteurized milk inoculated with 101 to 105 CFU/ml of a five-strain cocktail of acid-tolerant Escherichia coli O157:H7. Samples were collected during the cheese manufacturing process. After pressing, the cheese blocks were packaged into plastic bags, vacuum sealed, and aged at 7°C. After 1 week, the cheese blocks were cut into smaller-size uniform pieces and then vacuum sealed in clear plastic pouches. Samples were plated and enumerated for E. coli O157:H7. Populations of E. coli O157:H7 increased during the cheese-making operations. Population of E. coli O157:H7 in cheese aged for 60 and 120 days at 7°C decreased less than 1 and 2 log, respectively. These studies confirm previous reports that show 60-day aging is inadequate to eliminate E. coli O157:H7 during cheese ripening. Subpasteurization heat-treatment runs were conducted at 148°F (64.4°C) for 17.5 s on milk inoculated with E. coli O157:H7 at 105 CFU/ml. These heat-treatment runs resulted in a 5-log E. coli O157: H7 reduction.
