Juice

    I’ve always been wary of those fresh squeezed juice places; and those infomercials where all the dirty carrots, oranges, apples and anything else are tossed in for power juice.

    Scientists from the University of Valencia in Spain analyzed 190 fresh orange juice squeezed by machines in catering establishments and found that 43% of samples exceeded the acceptable level of enterobacteriaceae, 12% exceeded mesophilic aerobic microorganism levels, Staphylococcus aureus was found in 1% of samples, and salmonella was found in 0.5% of samples.

    Isabel Sospedra, one of the authors of the study appearing in Food Control, warns that, "generally a percentage of oranges juice is consumed immediately after squeezing but, as in many cases, it is kept unprotected in stainless steel jugs."

    The scientists found that some juices that were kept in metal jugs presented "unacceptable" levels of enterobacteriaceae in 81% of cases and in 13% of cases with regards to mesophilic aerobic bacteria. However, when the freshly squeezed juice is served in a glass, these percentages fall to 22% and 2% respectively.

    “It must also be borne in mind that juicers and juicing machines have a large surface area and lots of holes and cavities. This promotes microbial contamination, which is picked up by the juice as it is being prepared."

    The researchers recommend that oranges are handled correctly, that juicers are washed properly and that the orange juice is served immediately rather than being stored in metal jugs.

    In 2009, Spaniards drank 138 million litres of orange juice (according to data provided by the Spanish Ministry of the Environment and Rural and Marine Affairs), 40% of which was freshly squeezed and consumed in catering establishments.

    A table of juice-related outbreaks is available at http://bites.ksu.edu/fresh-juice-outbreaks.

    Food safety types in Birmingham, U.K. have found that 40 per cent of all plastic packaging containing chicken in Birmingham contained food poisoning bacteria.

    In a survey of 20 supermarkets, convenience stores and butcher’s shops throughout the city, food safety officials found that eight were contaminated on the outside of the packet.

    They also found seven chickens were contaminated inside the wrapping, while one tested positive for salmonella. There was no link between those infected inside and outside the packaging.

    Team manager Nick Lowe said, “Our message to consumers is that handling the packaging should be regarded as just as likely to cause food poisoning and touching the raw meat.”

    Once handled in a supermarket the bacteria can be passed on through trolley handles, shopping bags and transferred to other foods. In one supermarket a pool of juice collected on the chiller shelf was also contaminated.

    With economic pressures, more food safety stuff gets farmed out to others.

    Whether enough food safety expertise remains in the company selling the product is questionable.

    Canwest News Service reported the DeGroot children, Johnny, now 9, and sister Jessica, 6, of Waterford, Ontario, are still battling parasites the family believes are linked to juice they consumed.

    More than 100,000 Strawberry Kiwi Dole juice boxes were eventually destroyed last year following a government investigation showing a container-integrity problem with the boxes during distribution. Weakened boxes can become bloated and leaky, making them magnets for bacteria and yeast.

    Newly released internal documents from the Canadian Food Inspection Agency about the affair reveal a food-safety system far from perfect, where flags during distribution might not have come to light had it not been for one determined family.

    And a leading food-science expert who reviewed the agency's final report into the matter says the case demonstrates an ongoing problem in the food industry.

    University of Guelph food science professor Keith Warriner said,

    "It was obvious to me that what they actually have, on paper, a system in place to detect the quality control of packaging, but they didn't actually practise what they preached. . . . It was more a case of the company, when a defect did occur, not acting upon it. That's very common in the food industry. … A lot of companies are subcontracting. Economically, it makes sense because if you subcontract, you don't have to pay for facilities. But if you haven't got control, it can literally collapse an organization so you've got to be careful.”

    Whole Foods Market has terrible food safety advice, blames consumers for getting sick, sells raw milk in some stores, offers up fairytales about organic and natural foods, and their own CEO says they sell a bunch of junk.

    This afternoon, the Whole Foods blog offers up, The Family Cow – Chambersburg, Pennsylvania, a heartwarming tale of nostalgic and scientific BS about the alleged virtues of raw milk.

    “The Family Cow’s fresh raw milk is not processed in any way, making it truly a whole food, alive with natural enzymes, immunity building probiotic bacteria and bursting with full-bodied flavor.”

    Check it out for yourself.

    The idea of Chapman calling others amateurs is amusing.

    P.J. O’Rourke wrote a National Lampoon column about how amateur drunks throw up on other people’s shoes. In Champan’s case, it would be other people’s rose bushes. That’s us, in 2000, at my house in Guelph. He barfed in the bushes.

    But Chapman, food safety specialist and assistant professor of food science at North Carolina State University, did get quoted by a paper in Nebraska today saying,

    "The biggest risk comes from undercooking. Color is not an indicator of safety or doneness. We see suggestions in recipes about making sure 'the juices run clear' but that's a myth. You also have to worry about cross-contamination -- which can happen when countertops, sinks or utensils aren't being cleaned properly between use with raw meats and other foods."

    And this was Chapman last weekend tailgating at the Kansas State football game. We left early because he had digestive upsets. Amateur.

    USDA FSIS has announced a recall of 545,699 pounds of fresh ground beef products that may be contaminated with E. coli O157:H7 and distributed in seven states. According to FSIS, the product has been linked to a cluster of illnesses in New England.

    There are quite a few recalls going on most of the time; this one is notable because this product has been linked to an outbreak of illnesses at a camp in Massachusetts. It's also notable because bulk amounts of the product were shipped down the East Coast for further processing. Retail outlets receiving some of this product include Shaw, Giant, Price Chopper,Trader Joe's, BJs and others.

    From the press release:
    "Products for further processing:
    Cases of 10-pound "FAIRBANK FARMS FRESH GROUND BEEF CHUBS."
         Each case bears the establishment number "EST. 492" inside the USDA mark of inspection; has package dates of "09.14.09," "09.15.09," or "09.16.09;" and sell-by dates of "10.3.09," "10.4.09," or "10.5.09. These products were distributed to retail establishments in Maryland, Massachusetts, North Carolina, New Jersey, New York, Pennsylvania, and Virginia for further processing. However, these products at retail will likely not bear the package dates and sell-by dates listed above. Customers with concerns should contact their point of purchase."


    It is unlikely that any of the product is still being sold fresh at retail stores (the best-if-sold-before dates range from mid-September to early October) but it's likely that the affected beef is still around in freezers. The meat juices from thawing can provide a nice vehicle for pathogen transfer.

    Stick it in with a tip-sensitive digital thermometer (in multiple spots) to ensure that ground beef has reached a safe temperature and be vigilant in containing meat juices when thawing frozen meats. Juicy is good, nasty meat juice spread around the kitchen isn't.

    In part two of the Toronto Star's investigation of soft-serve ice cream safety reporters have stumbled upon a snack bar with an extraordinary amount of coliform in the treats. The biggest offender found during the blitz was the Kew Gardens snack bar (with coliform above 1000000 cfu/gram). When I was growing up, I probably visited that snack bar 10-15 times a summer.

    When asked about the 1000000 cfu/g measure, Rick Holley, microbiologist from U of Manitoba responded:

    "Oh my God. This is not good," With results this high, "the product is hazardous," said Holley, adding the spectre of serious health implications is also magnified.

    "The real concern here is listeria," he said. "And it's going to happen."

     After learning of the result on Thursday, [Kew Gardens snack bar] manager Danny Foulidis ordered the machine shut down and sanitized.

    "We've always been a clean establishment. We've never had an issue. If there's something we need to change to make things better, it's not a problem on our part."

    During the past week, Gerry Lawrence, food safety manager at Toronto Public Health, has fielded calls from worried residents asking how to tell if soft ice cream is safe.

    His advice: "If I'm buying ice cream for a youngster, I don't think I want to buy it from somebody that has greasy hands or isn't wearing a clean smock or even a baseball cap."

     Holley, a member of a federal advisory panel struck in response to the Maple Leaf Foods listeria crisis, chuckles at the suggestion that protection comes down to gauging the cleanliness of an operator. "That's not the complete picture. You might have one person of that kind of appearance who plays a very minor role in handling products that are risky, such as these are.

    Great quote by Holley after a poor suggestion from Lawrence. Visual cleanliness isn't a good indicator of anything, especially whether someone is going to get sick. 

    "It really does require that the folks who are responsible for making sure that all of the licence requirements of these people are met are conscientious in what they do and look at the whole picture. Whether or not they have time to do that is another issue."

    The Star goes on to report on one of the factors that could lead to soft-serve contamination, the infamous O-ring.

    Health inspectors generally do not check the inner mechanisms of machines, and experts warn that's where the danger lies, particularly in a $1.85 rubber O-ring that seals an area around a drive shaft that spins the ice cream. Michael Minor, former president of the Ontario branch of the Canadian Institute of Public Health Inspectors, said a worn ring can cause contamination to seep into the ice cream.

    "Product that leaks from the refrigerated mixing vat into the back of the machine because of a faulty O-ring can be pulled back in to the soft-serve mix through reverse flow," Minor said.

    Manufacturers suggest the rings be replaced every three months.

    Minor is concerned some operators lack the knowledge or will to maintain their machines, which is central to assuring a safe product.

    "This is not rocket science. It's not statistical analysis. This is a machine that needs attention and you need to understand it."

    Holley and Minor both touch on one of the tenets of food safety culture: Operators need to know the risks associated with their products and how to manage them. Good operators know about sanitation, equipment maintenance and selecting good suppliers.

    In keeping with the storyline of idiots who think 911 is their babysitter, a  man who called 911 to complain that McDonald's left a juice box out of his drive-through order was arrested on Monday, Portland television station KPTV reported.

    Raibin Osman appeared before a Washington County judge Tuesday on a charge of misusing emergency services. He said he called emergency dispatchers after the drive-through employee wouldn't come back to the window to give him a juice box.

    On Days of Our Lives today, Victor Kiriakis gave his opinion about Chloe Lane, “Hell, botulism is better than being married to her.” In food safety terms, that’s a very low blow.

    Botulinum is a deadly toxin that comes from bacteria in soil and grows in warm, moist environments with no oxygen and low acidity. For example, it can grow on a baked potato wrapped in foil and left out on the counter. There have also been cases of poisoning in carrot juice, home-canned green beans, and enchiladas in France.

    Botulism can cause serious complications such as paralysis and death.

    Common symptoms include difficulty swallowing or speaking, facial weakness, double vision, trouble breathing, nausea, vomiting, abdominal pain and paralysis.

    In infants, symptoms include constipation followed by "poor feeding, lethargy, weakness, pooled oral secretions, and wail or altered cry. Loss of head control is striking."

    If having botulism is better than being married to Chloe, then Lucas better hope Victor, Kate, Sammy or even Daniel will ruin that wedding (you can vote online at nbc.com).

    And p.s., Victor Kiriakis is played by John Aniston, the father of Jennifer Aniston IRL.

    You can pee on the ice, but not in an ice machine.

    Four juveniles are facing several charges after security cameras showed them urinating into a cafeteria ice machine at a Chapel Hill,North Carolina middle school.

    The News & Observer of Raleigh reported Tuesday the boys range in age from 12 to 15, and are charged with breaking and entering, larceny and vandalism to a public building. Because they are under 16, their names are being withheld.

    Police said the vandalism occurred Dec. 15 at Smith Middle School in Chapel Hill. School officials said the ice machine was used on the following three days.

    But all the machine's ice and containers were removed when school officials learned of the incident.

    Public health officials instructed the school staff on how to clean and disinfect the surfaces and equipment before using them again.
