Aerosolization of pathogens? Petting zoo returns to Minn. fair after 2014 E. coli outbreak

Zerebko Zoo Tran, a traveling petting zoo, is returning to the 2015 Rice County Fair, a year after it was suspected to be the source of an E. coli outbreak.

courtlynn.petting.zooIn 2014, the Minnesota Department of Health identified 13 people from four different events who developed E. coli after visiting the Zerebko Zoo Tran traveling petting zoo.

 But Rice County Fair officials say fair goers shouldn’t be worried. Rice County Fair Executive Director John Dvorak said they were comfortable bringing Zerebko Zoo Tran back.

“The biggest factor is that they were extremely cooperative in working with the department of health, and others with the investigation,” Dvorak said.

Dvorak said the fair has also made changes to the facilities fair goers can use to clean up after visiting the zoo. In the past, the fair supplied hand-washing stations that used a chemical to sanitize hands. This year, the fair is bringing running-water hand washing stations with soap.

“E. coli is best cleaned away by friction, so by bringing the running water hand washing stations, that will help get rid of anything that could be spread,” Dvorak said.

Operational changes have been made in the fairground’s barns, like keeping an extra eye to keep walkways clear of waste and making layout changes within the barns so animals never have to step outside to go to a different part of the barn, he said.

Wally Zerebko, owner of Zerebko Zoo Tran, said after the incident in 2014, he contacted several experts and had all of his animals tested. He also had the company’s vet mention the problem at a conference, which led to them finding a vaccine they could give the animals.

Settlement reached in XL Foods beef recall

A settlement has been reached in a class action lawsuit over the largest meat recall in Canadian history.

XL.fine.foodsThe lawsuit was launched against XL Foods based in Brooks, Alberta after 18 people got sick with E. coli after eating tainted meat in 2012.

The majority of the $4 million settlement will go to those poisoned by the meat, health care providers and claims will also be paid out to consumers who had to throw out the tainted products.

The settlement still has to be approved by the courts.

Portland, I’m about to be in you; get rid of your Salmonella

I’m all caught up on my Portlandia viewing, I’ve got my beard trimmed and my suspenders packed.

I’m even going to bring my mason jars to drink out of.

I’m ready for IAFP in Portland.

Maybe the conference karma will be better for the food safety nerds than it was for attendees of the Open Source Bridge Conference. According to conference organizers, health authorities at least 50 attendees of the developers conference came away with salmonellosis.

We have determined that Salmonella caused gastrointestinal illness among conference attendees. Laboratory tests helped investigators identify a distinct Salmonella strain (Salmonella typhimurium) in six attendees who became ill between June 26th and June 30th. In addition to these six cases, 45 other people reported having symptoms consistent with Salmonellosis. They were among more than 220 conference attendees who responded to a Health Department survey that conference organizers shared last week.

The Health Department is continuing its investigation to identify the source of the bacteria that caused the illness. There is no indication that this outbreak spread beyond people connected to the conference. We are monitoring illness in Oregon to assure this is the case.

Annals of great headlines: Blue Bell ice cream finds a sugar daddy after Listeria meltdown

CNN Money reports that Blue Bell Creameries, the ice cream maker that has been shutdown by listeria contamination tied to at least three deaths, has found a billionaire investor to help it get back on its feet.

blue.bell.scoopsThe company announced Tuesday that billionaire Sid Bass has become a partner. Bass, 73, is worth an estimated $1.7 billion, according to the latest estimate from Forbes. He has worked at his family’s investment firm his entire career, notably in its oil and gas holdings and the large stake it once held in the Walt Disney Co. (DIS)

Blue Bell was a leading ice cream brand in the southern U.S., but it had to recall all of its products in April after discovering widespread contamination by the listeria bacteria, which can survive at colder temperatures than most other deadly bacteria.

The business has been family owned for 108 years and does not release financial data. Estimates were that it was the nation’s fourth largest ice cream maker behind Nestle (NSRGF), maker of Dryer’s and Edy’s ice cream brands, Unilever (UL), which makes of Breyers and Ben & Jerry’s, and Wells Enterprises, which makes Blue Bunny.

Discard produce tainted by flood waters

West Virginia agricultural officials are advising growers to discard vegetables that have had contact with flood waters.

flood.midwestThe advice comes after weeks of rain that promoted Gov. Earl Ray Tomblin to declare states of emergency in 10 counties this week.

West Virginia extension agent John Bombardiere says the safest way to deal with lettuce, tomatoes or potatoes that have been tainted by flood water is to toss them. He says they should not be consumed by humans or animals.

The advice is based U.S. Food and Drug Administration guidelines, which state there is no practical way to salvage the product.

12 now sick with E. coli O157 linked to UK butcher

Four more reports of E. coli O157 infections in the North East have been received by health officials in the last 24 hours

butchers.jpg-pwrt3This brings the total number of people affected to 12, of which five are in hospital.

Four of the people in hospital are children aged between eight and fourteen. The fifth person in hospital is an adult.

Although a definite source has not yet been identified, many of the affected people are known to have eaten pre-cooked meats or savoury products supplied by Robinson’s butcher and caterer who have shops in Wingate and Billingham.

Escherichia coli O157 outbreaks in the United States, 2003–2012

Infections with the Shiga toxin–producing bacterium Escherichia coli O157 can cause severe illness and death.

e.coli.O157.strawberryWe summarized reported outbreaks of E. coli O157 infections in the United States during 2003–2012, including demographic characteristics of patients and epidemiologic findings by transmission mode and food category.

We identified 390 outbreaks, which included 4,928 illnesses, 1,272 hospitalizations, and 33 deaths. Transmission was through food (255 outbreaks, 65%), person-to-person contact (39, 10%), indirect or direct contact with animals (39, 10%), and water (15, 4%); 42 (11%) had a different or unknown mode of transmission. Beef and leafy vegetables, combined, were the source of >25% of all reported E. coli outbreaks and of >40% of related illnesses.

Outbreaks attributed to foods generally consumed raw caused higher hospitalization rates than those attributed to foods generally consumed cooked (35% vs. 28%). Most (87%) waterborne E. coli outbreaks occurred in states bordering the Mississippi River. 

Market food safety: Can big meat get it?

If companies don’t tell their story, they leave themselves vulnerable to others, who will gladly tell their version of the story.

JBS-Meat-Cooler-590x332NPR says that food companies the world over are paying close attention to the groundswell of support for food transparency, the “know where your food comes from” movement.

JBS, the largest meat producer in the world, is beginning to take notice as well.

But executives with JBS USA, the North American arm of its Brazilian parent company, at the same time acknowledge that the very nature of their business is grisly, gory and sometimes unpalatable.

“Part of you says, ‘I need to learn how to bring the packing house into the consumer’s living room,'” says Bill Rupp, president of the company’s beef division. “Then at the same time, you think of all the pitfalls of trying to explain to consumers how we harvest their meat.”

“I think in today’s society, the consumer wants to know more and more where their food comes from. And food companies are slowly adopting toward that,” says Cameron Bruett, JBS USA spokesman. “But I think we need to do a better job.”

JBS owns numerous plants cross the Midwest, South and West of the U.S., as well as worldwide. The JBS meatpacking plant in Greeley, Colo., is an imposing building. Conveyor belts snake through the concrete structure. But it’s not an assembly line. Workers in blood-spattered smocks disassemble cattle, breaking down whole animals into cuts of meat.

During a guided tour for journalists, the plant’s manager, Bill Danley, points to a line of men carving the animal’s head. “These guys here, what they’re doing is, they’re taking the cheek meat off,” Danley says. “There’s head meat on top of that. A lot of your taco filler is made out of cheek meat and head meat.”

Taco meat is just the beginning. This one cow is destined to be sirloin at steakhouses, ground hamburger at local grocery stores and leather for car seats.

JBS spokesman Bruett says for a long time, beef has been a commodity, shipped out from meatpacking plants in boxes and rebranded at grocery stores and restaurants. Bruett says when your immediate customers are other businesses, there’s little value in telling your story.

 

Blueberries and bugs: Can UV light help?

Ultraviolet light (UV) has antimicrobial effects, but the shadowing effect has limited its application.

blueberriesIn this study, a novel setup using UV processing in agitated water was developed to inactivate Escherichia coli O157:H7 and Salmonella on blueberries.

Blueberries were dip- or spot-inoculated with E. coli or Salmonella. Blueberries inoculated with E. coli were treated for 2 to 10 min with UV directly (dry UV) or immersed in agitated water during UV treatment (wet UV). E. coli was most easily killed on spot-inoculated blueberries with a 5.2-log reduction after 10-min wet UV treatment. Dip-inoculated blueberries were the most difficult to be decontaminated with only 1.6-log reduction after 10-min wet UV treatment.

Wet UV treatment generally showed higher efficacies than dry UV treatment, achieving an average of 1.4 log more reduction for spot-inoculated blueberries. For dip-inoculated blueberries, chlorine washing and UV treatments were less effective, achieving <2 log reductions of E. coli. Thus, the efficacy of combinations of wet UV with sodium dodecyl sulfate (SDS), levulinic acid, or chlorine was evaluated. Inoculated blueberries were UV-treated while being immersed in agitated water containing 100 ppm SDS, 0.5% levulinic acid or 10 ppm chlorine.

The 3 chemicals did not significantly enhance the wet UV treatment. Findings of this study suggest that UV treatment could be used as an alternative to chlorine washing for blueberries and potentially for other fresh produce.

Practical Application

A novel UV light system for decontamination of blueberries in water was developed and evaluated. Results demonstrated that the decontamination efficacy of this system was generally as effective as chlorine washing, indicating that it could potentially be used as an alternative to chlorine washing for blueberries and other fresh produce.

Don’t serve food when you’re sick: Almost 300 in mass lawsuit over UK Toby Carvery norovirus outbreak

The number of people who are taking legal action against an Exeter restaurant following an outbreak of norovirus has nearly reached 300.

toby.carvery.exeterLawyers are investigating the norovirus outbreak at Toby Carvery at the Exeter Arms, Middlemoor.

Irwin Mitchell have now revealed that it is representing 285 people in relation to the case.

They believe more than 300 people may have been affected by the outbreak.

The restaurant chain confirmed that tests run by the Environmental Health department, after a man was sick in the restaurant foyer in the evening of Sunday, March 29 tested positive for the virus.

The pub underwent a deep clean overnight on Thursday, April 2, but continued to trade over the busy Easter bank holiday weekend when more customers fell ill, finally closing on Tuesday, April 7.
