Stadium food safety practices not always a home run

When I turned 16 years old my dad and I (below, exactly as shown) took a trip around the somewhat North Eastern U.S. and caught a bunch of baseball games at MLB parks. In the summer, baseball dominated the TV in our house (my dad was a Yankees fan, and in a true reflection of rebellion, I grew up a Mets fan) so this was the trip of a lifetime for both of us.

This was back before the tubes of the Interwebs were in everyone’s homes (we did have a 1200 baud modem on a 486) so getting tickets was tricky. We picked up a Street & Smith’s baseball preview magazine (complete with schedules and box office contact information) in March and over the Easter weekend planned out the route. We called to order tickets and waited a few weeks.
 
Setting out on an early July morning, we drove down the 401 (that’s a highway in Ontario) towards our first stop in Montreal listening to mix tapes I had made (my dad was particularly harsh on my Pearl Jam selections). The trip was a true father/son bonding experience and is definitely one of the fondest memories of my childhood.  In 9 days we hit games in 7 stadiums (Montreal, Philly, Pittsburgh, Cleveland, Cincy, Detroit and Toronto) without much of a hitch (no rainouts, car troubles or bad seats). I even caught a ball in Cincy, which is still around and Jack has now discovered. 
 
In each of the stadiums my dad and I ate a standard hot dog (to compare and rate) as well as a sample of the local food specialty (poutine in Montreal, cheesesteaks in Philly, etc.). I wasn’t the healthiest eating teenager.
 
Like it was for my dad and I, food is a big part of the stadium experience for many. In a perfect intersection between two of my passions, ESPN’s Outside The Lines magazine show focused half an episode on food safety at the 107 major sports stadiums in Canada and the U.S., telling a not-so-flattering story.
 
ESPN’s "Outside the Lines" reviewed health department inspection reports for food and beverage outlets at all 107 North American arenas and stadiums that were home to Major League Baseball, National Football League, National Hockey League and National Basketball Association teams in 2009. At 30 of the venues (28 percent), more than half of the concession stands or restaurants had been cited for at least one "critical" or "major" health violation. Such violations pose a risk for foodborne illnesses that can make someone sick, or, in extreme cases, become fatal.
 
Bob Buchanan, food safety guru, was cited as saying:
 
"That number [the 30 venues with a majority of food establishments having critical violations], based on comparisons of the data I’ve been able to find on restaurants in general, is substantially higher than I would have expected. Certainly, if you have a high rate of facilities within a stadium coming up with critical deficiencies, that to me strikes of systemic errors in either management of the stadium or in the infrastructure of the stadium, and both of them need to be corrected."
 
Bang on Bob; practices are related to the culture within the organization from the manager’s attitude all the way to the front-line staff.
 
Steven Weiss, of Aramark, one of the stadium food providers focused on in the story was quoted as saying,"The most important thing for people to know is that food safety is our top priority. There’s nothing more important." That’s a great start, but unless everyone in the organization knows and values food safety in the same way food safety slips down the priority list, and as Bob said, bad practices can become systemic. And investigative reporters will find the multiple and repeated transgressions.
 
Our food safety infosheet evaluation study also made the companion piece on the website, supporting something an ex-frontline food handler Nicholas Casorio said,  "There’s so much volume going through at one time that it’s hard to do the necessary things to keep everything clean. Sometimes you sacrifice the cleanliness for expediting the service."
 

Last fall I took my dad to a Carolina Hurricanes game and we debated getting a bbq sandwich after the first period but the price tag was a bit steep ($7). My dad asked me "So, how do you think they are doing, food safety-wise".

I told him that it’s tough to say, anytime you eat you put trust in a food handler somewhere and hopefully they know somthing about risks and risk reduction. After the game I dug up some inspection reports. I couldn’t find the Carolina BBQ stand in question but was able to browse through 20 or so other RBC Center sites from the past couple of years. Temperature abuse, especially hot-holding seemed to be a common violation.

The bbq looked and smelled good, and judging by the lineups, was moved out of the pans to patrons’ sandwiches pretty fast. But who knows at what temperature, and how long it was held before we came by. I hope that someone did.

 

Iowa farmers’ market outbreak linked to guacamole, salsa and uncooked tamales

Associated Press reports tonight that recent illnesses connected to an Iowa farmers’ market are linked to Mexican foods sold by a common vendor,  La Reyna Supermarket & Taqueria of Iowa City.

The products were sold at farmers’ markets in Linn, Johnson and Dubuque counties and may be contaminated with salmonella. The departments say any guacamole, salsa and uncooked tamales should be thrown away and not eaten. The salmonella investigation was initiated by Linn County Public Health officials and illnesses were traced to products produced by the restaurant in Johnson County.

Bittman’s blog gets it right this time when it comes to botulism risks

Last year renwoned New York Times food dude Mark Bittman posted a recipe for a botulism surprise (disguised as a garlic-in-oil product) that was ammended after a few letters about safety. Today, one of Bittman’s colleagues and contributors to his blog, Kerri Conan writes about a way to make "quick pickles" apparently the wrong way.

According to Conan, to make the skillet pickles:

Start with trimmed whole or sliced vegetables (in this case green beans but I later made a batch with beets) and a hot skillet filmed with olive oil. Add some aromatics (the first garlic from the garden for the first; the other got a mixture of sesame and grape seed oils with scallions). When the seasoning just starts to sputter, toss in the veg. Move them around in the pan a bit so the color brightens evenly, then stir in a splash each of water and vinegar (I used sherry v. for the beans and rice v. for the beets, but your call).

Bring the whole lot to a boil and cook until the vegetables are about two clicks less tender than you eventually want them. Remove the pan from the heat to cool. Empty everything into a jar and chill, shaking the contents often. Polish them off in a few days.

Conan’s recipe sounds a bit more like a salad, but included in this post (unlike Mark’s last year) is the addition of a refrigeration step for preserving the product, and the mention of eating it within a couple of days. Chilling is a good tip, green beans with the addition of a "splash" of vinegar with a bunch of oil left on the counter for a few days could result in a serious public health issue. The pathogen of concern, Clostridium botulinum, could exist as spores on the suggested ingredients. Heating the foods may activate the spores and placing the flavor-making components into certain oils can create the perfect environment (oxygen-free and low acid) for cell growth and botulinum toxin formation.

Double wrap, separate and wash ’em: tips on keeping reusable grocery bags clean

At pretty well every conference or meeting I went to in 2008 and 2009 I was given a reusable grocery bag. A decent registration gift to hold programs, promotional materials and goodies – that served some post-meeting utility as well. Not a bad replacement for the laptop bags that were ubiquitous in the five years before. Lately meeting organizers have been giving out aluminum water bottles, another usable item. We’ve collected 6 or 7 reusable grocery bags and they are now in rotation for our weekly shops. 

A couple of weeks ago a press release about a study looking at the handling and microbiological content of a select group of bags was released.  What I wrote then was:

The study, when and if it is published will provide some nice baseline results on what people say they do, demonstrates the effect of washing, and doesn’t like some try to point out really say that plastic bags are any safer (there was no comparison) but there are a couple of things missing that could really have been useful. Two big questions still need to be answered:

– Generic E. coli is floating around in bags, recoverable in the Gerba study in 12 % of those tested, but can it be (or is it likely) to be transferred to any ready-to-eat foods, or somehow to food contact surfaces in the home?

– What effect does drying have on the bags, if at any? According to Gerba et al., washing works, no one reports doing it; but what about flipping them inside out and drying bags for a few days after use?

After that post, a local TV station called about the study and conclusions and wanted to know a bit more about potential risks what people could do in their homes to reduce the chance of foodborne illness. My tips were what we do in our house: Wrap raw meats in a secondary plastic bag to create a barrier and catch any dripping juices; washing our bags every couple of weeks to remove anything that might be floating around and dedicating a reusauable bag as the “meat bag” and washing it more often, usually after every shop.
 

Bullock’s BBQ outbreak: It was the egg, in the meringue, with the Salmonella according to health officials

North Carolinians love their BBQ. As a relatively new transplant to the south I’ve embraced BBQ and have been learning the different nuances of both Eastern and Western NC BBQ (Eastern is vinegar based, Western has more tomato, both are pork). I like BBQ and while I travel around the state working on extension stuff I try to sample the local fare. Last week, while in Nash Co. NC, my team grabbed some lunch at Doug Saul’s BBQ and Seafood (Audrey and Ted are in the picture below, exactly as shown). It seemed like the local hangout, not unlike a rural Tim Horton’s in Canada, and the patrons were dressed in everything from suits to overalls. BBQ is a community thing.

A couple of months ago, Bullock’s BBQ in Durham was the source of a Salmonella-linked outbreak that caused 65 illnesses and resulted in 7 hospitalizations. Early on in the outbreak investigation the owner of the place initially blamed temperature abuse of a takeout order. After the outbreak sales dropped 80% and the usually busy restaurant was close to empty, but the source of the illness didn’t seem to matter to some community members as they rallied around.  At the time Sam Poley, marketing director for the Durham Convention & Visitors Bureau said, "This is a long-standing restaurant … 58 years in business … never had anything less than an ‘A’ health rating. Today is an important step in helping Bullocks solve a consumer confidence problem." Sure. But inspection results aren’t a great indicator of whether a business is going to have an outbreak or not.

Today, WRAL news reports that the Durham Co. Health Department has released information that suggests that supplier issues, not employees were the cause of the outbreak.

Initial tests found Salmonella bacteria in foods containing egg, and further investigation determined the likely source of the outbreak was bacteria in a commercially made egg white product the restaurant used to make meringue.

The health department found no violations of food handling practices at Bullock’s, a Durham institution that serves walk-in customers and has a booming catering business.

The Centers for Disease Control and Prevention noted similar outbreaks across the country linked to pasteurized egg whites sold by the same supplier and made at the same plant as the products delivered to Bullock’s officials said.

Tests conducted by the North Carolina Department of Agriculture and Consumer Services and other labs couldn’t conclusively prove that the product was contaminated with Salmonella.

Bullock’s BBQ did the right risk management step purchasing a pasteurized egg product to be used for a raw egg containing dish and couldn’t avoid illnesses, because these things happen and there is never a guarantee of 100% risk-free. It looks like the eggs but blaming their patrons initially wasn’t the best practice, a better plan would have been to say that they were sorry their food made people sick.
 

Kenosha Salmonella outbreak up to 26 cases

I think I was first introduced to Kenosha, Wisconsin from Weezer’s Happy Days-themed Buddy Holly video. It then resurfaced in That 70s Show as a big town where Eric and friends went to see my favorite movie of all time, Star Wars. I figured it was the burbs-heavy halfway stop between Chicago and Milwaukee that looked a lot like Shermer, Illinois.

Kenosha is home to a growing Salmonella outbreak where additional 16 cases have been confirmed over the past couple of days. According to Fox6, although a business has been temporarily closed as a precaution, health officials do not believe that it is the only source of the outbreak. The Milwaukee Journal Sentinel also reports:

The health department has not pinpointed a single source of the outbreak, although the department has closed Baker Street Restaurant and Pub on Green Bay Road in Kenosha and is testing employees, Bosovich said.

"We have not found anything there. We did it as a precaution to make sure the employees are negative before returning to work," she said.

The hospital emergency room doctor in the below video has a few gems on Salmonella that aren’t quite correct:

You will be vomiting within 6 hours after eating that food" (more like 12-72 hours -ben)

Mostly it’s because a restaurant has recieved a shipment of food that sits out with no refrigeration (food handler hygiene, common supplier of a ready-to-eat food or cooking temps are probably more likely -ben).
 

 

New food safety infosheet: Skokie Country Club in Glencoe Illinois linked to Salmonella illnesses

High class, chic kitchens aren’t immune from outbreaks. Neither are storied golf courses (including ones that have hosted a U.S. Open). The newest food safety infosheet focuses on the Skokie Golf Club in Glencoe, IL after being recently linked to an outbreak resulting in up to 80 cases of salmonellosis.

Food Safety Infosheet Highlights:
– The outbreak has resulted in 37 confirmed cases, 50 suspected cases and 8 hospitalization.
– Reunions moved following kitchen closure.
– Food handlers can transmit Salmonella without even showing symptoms.
– Only 3% of salmonellosis cases are officially reported.

E. coli outbreak linked to Colorado day care

According to Fox31, fourteen are ill with pathogenic E. coli after an outbreak at the Little Sailors Child Development center in Northglenn, CO. The health officials say that it’s "less severe"; press reports that it’s a mild strain. Seems a bit weird to me. Thirteen kids and a staff member ill with pathogenic E. coli (not sure what kind) seems pretty serious. Especially when the owner’s son displayed symptoms for over a month.

The Tri-County Health Department has announced that 14 people, 13 children and a teacher have been diagnosed with a mild strain of E. coli.
"It appears less severe," said Richard Vogt, M.D., with Tri-County. "We have to see how this plays out."
Saker Sus, the owner of Little Sailors, said his own son was showing symptoms for over a month.
Sus says his center is separating the children that show symptoms. "The reason we’re not sending them home is because we don’t want the parents to take them to a different child-care setting and spread the disease around."

Reacting to a boil-water advisory

Smithfield, NC has been under a boil-water advisory for the past couple of days as a result of the presence of coliform detected during routine testing. After further sampling, generic E. coli was found in the system (but water treatment seems to be working fine now).

Maybe I’m a bit sensitive to boil-water advisories because of my connections to Walkerton (the Ontario, Canada town where seven died and over 3000 became ill from E. coli O157 in the municipal water supply). In addition to marking my introduction to risk communication, I played hockey and baseball with a bunch of great dudes from the area while in Guelph and heard personal stories about the effects of the outbreak.

As I worked on my MSc and hanging out with the greenhouse vegetable industry in Leamington, Ontario, there seemed to be a boil-water advisory in the area every couple of months. Since there was a lot of municipal water used in packing sheds (mostly for washing tomatoes) each of the incidents triggered some sort of response by the on-the-ball producers. While some increased the amount of chlorine they were adding to the washing tanks (and implementing more frequent monitoring) the really keen producers removed water from the sorting system entirely for a couple of days — citing too much risk from introducing non-potable water.

Businesses that rely on potable water for production face a tough decision when the safety of supplies are in question.  In Smithfield,

health officials made the call for over 100 food-related businesses ordering closures until the boil-water advisory was lifted.

Larry Sullivan is director of the Environmental Health Division at the county’s health department. He said that while using bottled or boiled water works for households, it’s not a good enough solution for restaurants, which depend heavily on tap water.
"You still have hand washing, food prep and other things to consider," he said. "There’s also ice making."

Mmmmaggots on a plane

From the don’t-bring-spoiled-meat-onto-a-plane-file, a flight from Atlanta to Charlotte was forced to return to the gate prior to takeoff as maggots fell from the overhead bin onto passengers below.

U.S. Airways spokesman Todd Lehmacher says the maggots were in a container of spoiled meat that a passenger brought onto the plane Monday.

The plane returned to the gate and passengers got off so cleaning crews could clean the overhead bin.

Lehmacher says the flight then continued on to Charlotte, where the plane was taken out of service and fumigated out of an "abundance of caution."
