Shiga toxin producing E. coli in raw milk cheese in Ireland

Corleggy Cheeses is recalling all batches of its raw milk cheeses due to the detection of verocytotoxigenic Escherichia coli (VTEC) in two batches of its cow’s milk cheese.  The cheeses are supplied to some restaurants and retail shops.  They are also sold directly at food markets.  Consumers are advised not to eat the affected cheeses.

Corleggy CheesesVTEC may cause severe bloody diarrhoea and abdominal cramps, although sometimes the infection causes non-bloody diarrhoea or no symptoms. In some groups, particularly children under 5 years of age and the elderly, the infection can also cause a complication called haemolytic uraemic syndrome (HUS) in which the kidneys fail.

 

Largest botulism outbreak in 40 years in US: Botulism at church potluck in Ohio, 2015

The U.S. Centers for Disease Control reports that on April 21, 2015, the Fairfield Medical Center (FMC) and Fairfield Department of Health contacted the Ohio Department of Health (ODH) about a patient suspected of having botulism in Fairfield County, Ohio.

cannedpotatoes20091-300x214Botulism is a severe, potentially fatal neuroparalytic illness.* A single case is a public health emergency, because it can signal an outbreak (1). Within 2 hours of health department notification, four more patients with similar clinical features arrived at FMC’s emergency department. Later that afternoon, one patient died of respiratory failure shortly after arriving at the emergency department. All affected persons had eaten at the same widely attended church potluck meal on April 19. CDC’s Strategic National Stockpile sent 50 doses of botulinum antitoxin to Ohio. FMC, the Fairfield Department of Health, ODH, and CDC rapidly responded to confirm the diagnosis, identify and treat additional patients, and determine the source.

A confirmed case of botulism was defined as clinically compatible illness in a person who ate food from the potluck meal and had 1) laboratory-confirmed botulism or 2) two or more signs of botulism or one sign and two or more symptoms† of botulism. A probable case was a compatible illness that did not meet the confirmed case definition in a person who ate food from the potluck meal.

Among 77 persons who consumed potluck food, 25 (33%) met the confirmed case definition, and four (5%) met the probable case definition. The median age of patients was 64 years (range = 9–87 years); 17 (59%) were female. Among 26 (90%) patients who reported onset dates, illness began a median of 2 days after the potluck (range = 1–6 days).

Twenty-seven of the 29 patients initially went to FMC. Twenty-two (76%) patients were transferred from FMC to six hospitals in the Columbus metropolitan area approximately 30 miles away; these transfers required substantial and rapid coordination. Twenty-five (86%) patients received botulinum antitoxin, and 11 (38%) required endotracheal intubation and mechanical ventilation; no other patients died. Within 1 week of the first patient’s arrival at the emergency department, 16 patients (55%) had been discharged. Among 19 cases that were laboratory-confirmed, serum and stool specimens were positive for botulinum neurotoxin type A or Clostridium botulinum type A.

Interviews were conducted with 75 of 77 persons who ate any of the 52 potluck foods. Consumption of any potato salad (homemade or commercial) yielded the highest association with probable or confirmed case status (risk ratio [RR] = 13.9; 95% confidence interval [CI] = 4.6–41.8), followed by homemade potato salad (RR = 9.1; CI = 3.9–21.2). Of 12 food specimens collected from the church dumpster, six were positive for botulinum neurotoxin type A; five contained potato salad and one contained macaroni and cheese that might have been contaminated after being discarded.

The attendee who prepared the potato salad with home-canned potatoes reported using a boiling water canner, which does not kill C. botulinum spores, rather than a pressure canner, which does eliminate spores (2). In addition, the potatoes were not heated after removal from the can, a step that can inactivate botulinum toxin. The combined evidence implicated potato salad prepared with improperly home-canned potatoes, a known vehicle for botulism (3).

This was the largest botulism outbreak in the United States in nearly 40 years (Table). Early recognition of the outbreak by an astute clinician and a rapid, coordinated response likely reduced illness severity and facilitated early hospital discharge. This outbreak response illustrates the benefits of coordination among responders during botulism outbreaks. Close adherence to established home-canning guidelines can prevent botulism and enable safe sharing of home-canned produce (2).

QR codes for restaurant inspection disclosure in Sudbury

My sister, who lives in Sudbury (that’s in Canada), may be pleased to know the Sudbury and District Health Unit has asked restaurants to put new decals in their window. The decals include a code people can scan with their cell phone to access health inspection results.

UnknownThe Food Safety manager with the health unit said making restaurant cleanliness information easily accessible is important.

“[It gives] the consumer the information at hand to make the best decision possible [about] whether they choose to eat at that place or not,” Cynthia Peacock-Rocca said.

The decal program is voluntary for restaurants. She noted creating a mandatory program would have required legislative changes in all the municipalities the health unit serves.      

The results of inspection reports have been available on the health unit website since 2009.

organic-manure1Consumers of organic foods are getting both more and less than they bargained for. On both counts, it’s not good.

Many people who pay the huge premium—often more than a hundred percent–for organic foods do so because they’re afraid of pesticides.  If that’s their rationale, they misunderstand the nuances of organic agriculture. Although it’s true that synthetic chemical pesticides are generally prohibited, there is a lengthy list of exceptions listed in the Organic Foods Production Act, while most “natural” ones are permitted. However, “organic” pesticides can be toxic.  As evolutionary biologist Christie Wilcox explained in a 2012 Scientific American article (“Are lower pesticide residues a good reason to buy organic? Probably not.”): “Organic pesticides pose the same health risks as non-organic ones.

Another poorly recognized aspect of this issue is that the vast majority of pesticidal substances that we consume are in our diets “naturally” and are present in organic foods as well as non-organic ones. In a classic study, UC Berkeley biochemist Bruce Ames and his colleagues found that “99.99 percent (by weight) of the pesticides in the American diet are chemicals that plants produce to defend themselves.” Moreover, “natural and synthetic chemicals are equally likely to be positive in animal cancer tests.” Thus, consumers who buy organic to avoid pesticide exposure are focusing their attention on just one-hundredth of one percent of the pesticides they consume.

Some consumers think that the USDA National Organic Program (NOP) requires certified organic products to be free of ingredients from “GMOs,” organisms crafted with molecular techniques of genetic engineering. Wrong again. USDA does not require organic products to be GMO-free. (In any case, the methods used to create so-called GMOs are an extension, or refinement, of older techniques for genetic modification that have been used for a century or more.) As USDA officials have said repeatedly:

Organic certification is process-based. That is, certifying agents attest to the ability of organic operations to follow a set of production standards and practices which meet the requirements of the Organic Foods Production Act of 1990 and the [National Organic Program] regulations . . . If all aspects of the organic production or handling process were followed correctly, then the presence of detectable residue from a genetically modified organism alone does not constitute a violation of this regulation. [emphasis added]

Putting it another way, so long as an organic farmer abides by his organic system (production) plan–a plan that an organic certifying agent must approve before granting the farmer organic status–the unintentional presence of GMOs (or, for that matter, prohibited synthetic pesticides) in any amount does not affect the organic status of the farmer’s products or farm.

Under only two circumstances does USDA sanction the testing of organic products for prohibited residues (such as pesticides, synthetic fertilizers or antibiotics) or excluded substances (e.g., genetically engineered organisms). First, USDA’s National Organic Production Standards support the testing of products if an organic-certifying agent believes that the farmer is intentionally using prohibited substances or practices. And second, USDA requires that certifying agents test five percent of their certified operations each year. The certifying agents themselves determine which operations will be subjected to testing.

The organic community, including the International Federation of Organic Agricultural Movements (IFOAM), supports the USDA’s lenient testing protocols and opposes more frequent mandatory testing of organic products for prohibited and excluded substances.

The organic community and USDA offer two explanations for such minimal testing. First, they emphasize that organic farming is process-based, not product-based, meaning that what counts for organic certification are the approved organic system (production) plan and the farmer’s intention to comply with that plan as reflected through record-keeping obligations.

Second, widespread testing would impose substantial costs on organic farmers, thereby increasing production costs beyond the already greater expenses that organic farmers incur. Organic farmers offset these higher productions costs by earning large premiums for organic products, but there is always a price point beyond which consumers will shift to cheaper non-organic.

Few organic consumers are aware that organic agriculture is a “trust-based” or “faith-based” system. With every purchase, they are at risk of the moral hazard that an organic farmer will represent cheaper-to-produce non-organic products as the premium-priced organic product. For the vast majority of products, no tests can distinguish organic from non-organic—for example, whether milk labeled “organic” came from a cow within the organic production system or from a cow across the fence from a conventional dairy farm. The higher the organic premium, the stronger the economic incentive to cheat.

Think such nefarious behavior is purely theoretical? Think again. USDA reported in 2012 that 43 percent of the 571 samples of “organic” produce tested violated the government’s organic regulations and that “the findings suggest that some of the samples in violation were mislabeled conventional products, while others were organic products that hadn’t been adequately protected from prohibited pesticides.”

How do organic farmers get away with such chicanery?  A 2014 investigation by the Wall Street Journal of USDA inspection records from 2005 on found that 38 of the 81 certifying agents–entities accredited by USDA to inspect and certify organic farms and suppliers—“failed on at least one occasion to uphold basic Agriculture Department standards.” More specifically, “40% of these 81 certifiers have been flagged by the USDA for conducting incomplete inspections; 16% of certifiers failed to cite organic farms’ potential use of banned pesticides and antibiotics; and 5% failed to prevent potential commingling of organic and non-organic products.”

Speaking of trust and faith—or lack thereof–in organic foods, there was the example of holier-than-thou Whole Foods importing large amounts of its supposedly “organic” produce from China, of all places. Those imports even included Whole Foods’ house brand, “California Blend.” (Yes, you read that correctly.)

Organic agriculture is an unscientific, heavily subsidized marketing gimmick that misleads and rips off consumers, both because of the nature of the regulations and cheating. The old saying that you get what you pay for doesn’t apply when you buy overpriced organic products.

15 sick in UK E. coli O157 outbreak

Public Health England confirmed today that the owners of Robinsons butcher’s on Neasham Avenue have agreed to a voluntary closure.

butchers.jpg-pwrt3-300x225It comes amid reports of a new case of the E.coli O157 infection in a person who may have eaten ready-to-eat products from the shop is investigated.

The latest case brings the total number of people affected by the outbreak to 15.

A previous case reported to Public Health England has since tested negative.

Of these cases, two children and two adults remain in hospital. Two other children previously in hospital have been discharged and are recovering at home.

The children are aged between eight and 14 and two of them are known to be pupils at Northfield School and Sports College.

No one from Robinsons butcher’s was available for comment.

How to publish a scientific paper (not)

Apparently I’ve published another peer-reviewed paper.

In 2011.

wayne's.world.notBased on some research I did in 1986.

My undergraduate degree is in molecular biology and genetics from the University of Guelph (like Chapman), and in the summer between third and fourth year I worked in a lab and met a girl.

That girl was a veterinary student, and I wanted to hang around, so we moved in together, started a family and I started a MSc.

I spent a lot of time with tomato plants.

And our efforts at gene sequencing were slow and labor-intensive.

I eventually quit the MSc and became editor of the school paper.

And eventually I went back to Guelph and did a PhD.

My contribution was probably minimal, I’m grateful to Dr. Robb for paying me, but when I publish a paper, I make sure all authors have a chance to review it and offer their edits.

Vascular coating: a barrier to colonization by the pathogen in Verticillium wilt of tomato

http://www.researchgate.net/publication/237163772_Vascular_coating_a_barrier_to_colonization_by_the_pathogen_in_Verticillium_wilt_of_tomato

Abstract

Massive infusion of conidia of Verticillium albo-atrum.

Reinke & Berthier induced synchronous secretion of vascular coating in the petiolar xylem vessels of resistant and susceptible tomato near-isolines. More coating formed earlier in resistant than in susceptible plants. In the susceptible plants secretion was delayed in colonized trapping site vessels, but initiated in surrounding uncolonized ones. Controls were infused with water. Samples were quantified by light microscope assay techniques at 18, 48, and 120 h postinoculation for the following parameters: (i) delayed coating effect, (ii) overall coating capacity, and (iii) ability of fungus to “escape” laterally from trapping site vessels. The results showed that susceptibility to Verticillium was absolutely correlated with the presence of the delayed coating effect in the plant and increased ability of the fungus to spread laterally. Treatment of inoculated resistant plants with an inhibitor of coating secretion resulted in conversion to the susceptible phenotype. The progeny of a genetic backcross for the dominant (Ve) and recessive (ve) alleles at the Ve locus (Velve × velve) were assayed for the same parameters as well as for disease resistance based on symptom expression. The results confirmed the previous observations and suggested that in tomato the delayed phenotype is recessive. The data strongly supports two hypotheses: (i) coating forms a barrier against fungal penetration and (ii) the timing of the coating response in trapping site vessels results, directly or indirectly, from expression of the Ve gene.

Make disclosure mandatory: Brisbane issues 445 infringements to businesses for breaching food safety standards and collects more than 500K in fines

Toronto, Los Angeles and New York have all figured out how to make restaurant inspection disclosure mandatory.

restaurant_food_crap_garbage_10It’s voluntary in Australia.

The council has revealed its worst offenders are among Brisbane’s most popular eateries including Fortitude Valley’s Golden Palace Chinese Restaurant, Subway in Chermside Westfield and Ahmet’s Turkish Restaurant in South Bank.

Lord Mayor Graham Quirk said the council had raked in more than $500,000 in fines from businesses breaching standards and had successfully prosecuted 27 cases.

Cr Quirk said in the past financial year it had cancelled food licences on 18 occasions and issued 48 immediate suspensions to businesses in breach of food safety standards as well as 620 improvement notices.

“Council also issued 445 fines to businesses during the year and finalised prosecution of 27 successful cases of Food Act 2006 breaches with fines totalling $579,700, for incidents,” he said.

Cr Quirk said its Eat Safe program, which was implemented in 2010, aimed to boost health and safety standards in licensed food businesses including both mobile food vendors to restaurants.

Popular Florida pizza chain temporarily shut down for live roaches crawling in the kitchen

I have nostalgic memories of Clearwater, because my grand parents owned a place there, but after being in Australia for four years, the other beaches seem sorta small.

hungrey.howiesAnd last time I was in Clearwater, Florida, it seemed sorta dumpy.

Hungry Howies at 1884 Drew St. in Clearwater had to temporarily close up shop and stop serving food for several hours after what the state found behind the kitchen doors.

On July 23 inspectors saw over 35 live roaches crawling all around the kitchen.

The state observed roaches crawling between the wall and grease trap located beneath the three-compartment sink, near the reach-in cooler and hand wash sink.

Other violations documented include build-up of food debris, dust or dirt on the floor fan, ceiling tiles and vents, a hole in the back door and another hole in the wall behind the mixer, pizza to-go boxes stored on the floor and food not properly marked with dates.

In addition, there was no proof employees had the required state approved food safety training.

Indian restaurant in Wales ‘disgusting’

The owner of the Royal Massala restaurant has been ordered to do unpaid work after admitting offences.

royalA rodent infestation, mouldy food and a dirty kitchen that put customers at risk have landed one Indian restaurant owner in court.

Inspectors uncovered a catalogue of health hazards at the Royal Massala in Pencoed, near Bridgend, and slapped it with a zero rating.

But owner Sheik Mohammed Anwar failed to clean up his act – receiving a rating of one in a follow-up inspection – and he has now been sentenced in court, according to a statement from Bridgend County Borough Council.

The council has also threatened to ban Anwar from managing any food business in the future.
