Seafood safety, roses and writing

Chapman is a shitty writer.

How he got a staff member named Katrina Levine, who can write, is beyond my grasp.

But, I’m content to be amazed at the world, not think too much about it, and be grateful for the beauty in a rose or an MPH who can put a couple of sentences together.

Katrina (whom I’ve never met) writes:

I’ve never been one who likes attention, but I’ll admit that during the 15 minutes of fame that came with the publication of Evaluating Food Safety Messages in Popular Cookbooks in the British Food Journal, I got a little excited every time someone wanted to interview me. Terrified, but excited.

During the 2 week media buzz that followed the press release, I did approximately 6 interviews, one of which was for Consumer Reports. Unlike most of the interviews, which were focused on our row with Gwyneth Paltrow or how her cookbook could give you food poisoning, the nice journalist I spoke with wanted my professional opinion on how to choose and prepare seafood safely.

As I said before in an earlier barfblog post, the media attention from this paper gave us an opportunity to share what we know about safe food handling while people were listening. So when this journalist asked me to talk about seafood food safety, share I did – for about 45 minutes.

The messages I shared ranged from safe thawing methods, such as running raw seafood under cold running water, to determining doneness using a thermometer or opacity. Sari Hararr of Consumer Reports writes:

In a hurry? For safe seafood, thaw frozen fish and shellfish under cold running water in a sealed plastic bag, then cook it right afterward, says Katrina Levine, M.P.H., a registered dietitian and an extension associate in food safety and nutrition at North Carolina State University in Raleigh

For thicker fish such as a salmon steak, you can slip the thermometer into a side of the fillet, Levine says. But because it’s almost impossible to use a thermometer on shellfish or a delicate fillet of sole, the USDA notes that it’s also considered safe to cook fish until the flesh is opaque and separates or flakes easily with a fork. Cook crabs, lobster, and shrimp until the flesh is opaque and pearly; clams, mussels, and oysters until their shells open; and scallops until they are milky white or firm and opaque.

Although seafood does not need to reach an internal temperature as high as some foods like ground beef – 145°F compared to 160°F for ground beef and 165°F for poultry – it’s not any less risky. Outbreaks of norovirus and Vibrio have been linked to raw or undercooked seafood.

We know that using a thermometer to check internal temperatures is the best practice for knowing when food is done. Yet, people are even less likely to use a thermometer on fish than on meat or poultry, and cookbook recipes are also less likely to include safe endpoint temperatures for fish. While raw or undercooked seafood may be trendy (sushi and raw oyster lovers – you know who you are), getting foodborne illness isn’t.

Moscow Mule: cool drink, bad idea

One of the trendiest drinks of 2017 is the Moscow Mule: a refreshing mix of vodka, ginger beer and lime juice.
Much of the cocktail’s appeal is down to the fact it’s often served in very Instagram-friendly copper-coloured mugs.
But now a US state department has issued a warning that these pretty vessels could give you food poisoning if they have not been specially made for cocktails.
The stark message comes from the state of Iowa’s Alcoholic Beverages Division, which has warned that copper and copper alloys are poisonous if consumed.
When these metals come into contact with food or drink with a pH level lower than 6, copper may leak into the edible substance and can be accidentally consumed.
The warning states: ‘High concentrations of copper are poisonous and have caused foodborne illness.’
The pH level of a Moscow Mule is well below 6, which is why Iowa and several other states have issued the warning as these cocktails are often served in copper mugs.

Symptoms of copper food poisoning can occur immediately which includes nausea, vomiting (green), diarrhea and can leave a metallic taste in the mouth.
Never a good idea to dispense high acid foods with anything copper but that drink sounds good.

Health inspections are not easy

The field of public health inspection is not easy; it is a difficult job, yet gratifying. I remember inspecting restaurants that were notorious for non-compliance and trying to work with them to improve their food safety behaviors. I believed in quality inspections and not quantity as health inspections are essentially a snap shot in time and I wanted to make a difference.

Sometimes it worked and sometimes it didn’t and it is frustrated when you feel like you haven’t made a difference. So I get the ideology of fines as a method to increase compliance.
But do fines actually work or is it the cost of doing business for some operators? What will the establishment look like in a month or two, did we influence change or not? I have done this in the past where I charged a facility for a number of significant non-conformance’s and they subsequently cleaned up, but a month later, they regressed to the same state that I initially found them. Our department did not have a risk-based approach at that time and so the operator wasn’t expecting me for another year…surprise…

It is all about behavior and behavior change.

The owner of an East Tilbury sandwich bar has been slapped with a fine of almost two-and-a-half thousand pounds.
The owner of Nancy’s Sandwich Bar has been ordered to pay £2,353 for failure to comply with food safety legislation.
Daniel Wood appeared at Basildon Magistrates on Monday July 24, 2017 and pleaded guilty to 11 food hygiene offences, following a visit by Thurrock Council’s food safety team in September last year.
Inspectors visited the premises and found a makeshift kitchen had been set up in a room previously used for storage without consideration to food hygiene or public safety.
As a result, the food outlet was rated with a ‘1’ on the Food Standards Agency’s food hygiene rating scheme.
But the owner has since made improvements and the bar’s rating has gone up to ‘4’.
The bar was fined £1,230 and ordered to pay £1,000 costs and £123 victim surcharge.
Portfolio Holder for Neighbourhoods, Cllr Sue MacPherson said: “During the visit, the premises and equipment were found in a filthy condition, but I am pleased to see that improvements have since been made.”

 

Costco recalls cut broccoli because of E. coli O26

Non O157 STECs aren’t new but it’s still kinda notable when they pop up in recalls. The more folks look, whether buyers or suppliers are testing for them, the more folks find.

In 2015 E. coli O26 caused 60 illnesses (including 22 hospitalizations) associated with Chipotle. No source was identified, but the pathogen has been seen in both meats and produce. Today’s winner is cut broccoli.

According to a CFIA post, Costco is recalling Gold Coast brand broccoli florettes after someone found the pathogen. Or as CFIA so helpfully says, ‘This recall was triggered by the company.’

Gold Coast has a food safety page on their website. They say stuff like, ‘Microbiological Testing Program – Our new, fully equipped, in-house Microbiological Laboratory performs raw product, in process, finished product, and environmental testing.’

and

‘All raw and finished products are “lot coded” and can be traced back to specific suppliers, growers, ranches, fields, and plots.’

I look forward to hearing more.

These sponges go to 14

Friend of barfblog, and frequent contributor (and modeler extraordinaire), Don Schaffner writes,

I’m always interested in the way microbiology is perceived in the popular culture. When peer reviewed research articles get wide pick up, I’m especially interested. This happened recently with an article on kitchen sponges. Rob Mancini has already blogged about this right here on barfblog, but I’d like to share my thoughts and perspectives.

The fact the kitchen sponges can be massively contaminated by high levels of microorganisms is not news. This has been shown repeatedly in the peer reviewed literature.

What was apparently new in this latest article was the application of “454–pyrosequencing of 16S rRNA genes and fluorescence in situ hybridization coupled with confocal laser scanning microscopy (FISH–CLSM)”. And I get it. Molecular-based methods are all the rage, and the ability to visualize the presence of microorganisms is very important.

But we shouldn’t lose sight of the fact that experimental design, and proper experimental controls are important no matter what sort of science you’re doing. When I dug a little deeper into the above article I was shocked to learn that all of their conclusions were based on a sample of 14 sponges. That’s right, 14 sponges. Furthermore, the authors make claims that “sponge sanitation methods appear not sufficient to efectively reduce the bacterial load in kitchen sponges”. How did they know this? Well when they were collecting those 14 sponges they asked the sponge owners “to specify whether they regularly apply special measures to clean their sponge. The procedures mentioned were: heating in a microwave and rinsing with hot, soapy water”. Of the 14 sponges collected, in five cases the sponge owners reported applying special measures, although the authors do not which of the five used microwaving and which used rinsing with hot, soapy water.

What’s my take away message from this? By all means, go out there and use the hot new technology. But please don’t forget that sample size is very important, and while surveying people for their opinion about what they do might be convenient, it’s no substitute for actually investigating. And if I had to predict the effect of washing sponges with hot soapy water? Probably no different than washing in cold soapy water.

And if anybody out there has access to “454–pyrosequencing of 16S rRNA genes and fluorescence in situ hybridization coupled with confocal laser scanning microscopy (FISH–CLSM)“ and wants to collaborate, I am available.

Food safety at fairs and festivals

Tanya Banuelos of the Argus Observer writes:

As the last few weeks of summer vacation dwindle down and families are taking advantage of outdoor food at barbecues, picnics and the county fair, it’s time to talk about warm weather and food safety.
With 100-degree weather expected this week, it’s important to remember how much sooner food can become perishable when it’s out in the heat.
When it comes to food safety, food handlers at the Malheur County Fair must adhere to health guidelines, and an inspector is on site throughout the week. And as with every year at the fair, for those who sell consumable goods, food safety is a priority for vendors, such as Awesome Blossom and Fiesta Guadalajara.
Rely on equipment
One of the key details to remember is the importance of temperature.
Modesto Vega, co-owner of Fiesta Guadalajara, said he is able to keep foods at the appropriate temperature during the fair with commercial equipment.

I have inspected my fair share of temporary events including festivals and fairs and not all vendors are equipped with commercial fridges, freezers, etc. If you got them, all the power to you. I would typically see a lot of residential equipment, some good and some bad. As long as cold/hot holding temperatures are maintained, I’m good.

There have been a myriad of outbreaks associated with outdoor events nationally and internationally. The ethnic nature and diversity of foods prepared coupled with extreme temperatures pose unique problems for public health types. Public health inspections of said facilities rarely assess behavioral practices; rather, they are focused on meeting Regulatory standards. Time commitment and lack of public health staff have a lot to do with this, I have experienced this personally.

Effective food safety training during these events is critical. A number of operators at fairs and festivals are typically required to take a mandatory 8- hour food safe course or variation thereof prior to the event. I would rather see on-site hands-on training during vendor set-up focusing specifically on their menu items to ensure food safety, a mini HACCP if you will. If a vendor intends on serving hamburgers, well let’s go over what you need to do to ensure that no one barfs from your hamburgers.

Therman Collins, who has been a food vendor at the fair for eight years, said the key to keeping food safe for consumption is to make it fresh and send it right on out, adding that when it comes to food safety, “we know it all.”
Time, temperature equally important
When food is already cooked, especially with warm temperatures, how long people keep their food outside is a cause for concern, according to the Oregon Health Authority.
Most picnic foods will only be safe on the table for two hours; however, if the air temperature is higher than 90 degrees Fahrenheit, then the food is only safe for an hour.
Most importantly, food should be kept out of the danger zone, where cold foods are recommended to be kept below 40 degrees Fahrenheit, and hot foods above 140 degrees Fahrenheit, according to the United States Department of Agriculture.

Greed: Two men imprisoned from the horsemeat scandal

This story is a good segue to promote my talk on food fraud at Bug Day on October 17th, 2017 in Winnipeg Manitoba. Bug Day is hosted by Health Sciences Centre in collaboration with the University of Manitoba’s Continuing Professional Development (CPD) Medicine Program.
Bug Day is Manitoba’s largest healthcare education event and it is held every year during National Infection Prevention & Control Week. 

Lucy Pasha-Robinson of the Independent writes:
Andronicos Sideras, 55, and Ulrik Nielsen, 58, were jailed at Inner London Crown Court for four years and six months and three years and six months respectively.The pair were found guilty of a conspiracy to sell 30 tonnes of horsemeat as beef, most of which entered the food chain. Sideras, one of the owners of meat manufacturer Dinos & Sons, mixed the products together before selling the meat to other firms. Nielsen, the Danish owner of FlexiFoods, bought horsemeat and beef from suppliers across Europe and had it delivered to Dinos in Tottenham, north London.Nielsen’s “right-hand man”, Alex Beech, 44, arranged for the shipments to be transferred and handled the accounting.

Some of the horses acquired for meat were racehorses injected with who knows what posing a myriad of possible chemical food safety concerns to consumers.

The majority of the meat, including some from farm horses not sold for slaughter, made it into the food chain and, while the face value of the fraud was £177,869, police said the true cost had probably run into millions of pounds.
Prosecutor Jonathan Polnay said the scandal had led to a “crisis of confidence” in the food supply chain which hit sales and there were a “very, very large number of victims” in this case.

There’s a lot of botulism in Ukraine this year

According to MiceTimes of Asia (great name) there have been 90 illnesses and nine deaths in 2017 from foodborne botulism in Ukraine this year. Seems like a lot. Home canned foods and dried fish have been linked to many of the illnesses. Dried fish and botulism seem to go together. Five bot cases in Germany and Spain were linked to dried fish in 2016.

To prevent botulism, you must carefully follow the canning of vegetables, fruits, meat, fish and mushrooms. Before the use of canned foods should be warmed to a temperature of 100°C for 30 minutes to destroy botulinum toxin.

In no case can not eat canned meat and fish, if the iron Bank is inflated or deformed.

Something may be lost in translation.

Just wash ’em: WaPo covers soap porn

Handwashing is making a pop culture splash this week with the New Yorker piece and today’s Washington Post article on the types of soap that serial hand washers (like a chef and recipe tester) prefer.

An owner of a restaurant group with six restaurants surely washes her hands countless times a day. Renee Erickson, a chef and cookbook author in Seattle, likes unscented soaps for a work environment. But for home, where one can have more fun, she says, “I have become a big fan of L:A Bruket’s cucumber and mint soap from Sweden”

We use whatever is on sale. Just wash ’em.

Australian swim star Ariarne Titmus reveals food poisoning setback before world titles

Tasmanian teenager Ariarne Titmus has revealed her world championship swimming success came off the back of a bout of food poisoning.

The 16-year-old represented Australia at the FINA World Swimming Championships in Budapest last week, winning a bronze medal with the 4 x 200m freestyle relay team.

Her performance in Budapest also ranked her fourth in the world for the 400 metres freestyle, behind record holder Katie Ledecky.

Titmus said she contracted food poisoning just days before her world championship debut, which heightened pre-race nerves.

“I didn’t really know how I was going to race because a week out from the competition I got food poisoning and I was actually vomiting the weekend before racing started,” she told ABC Hobart.

“But I was positioned next to Katie Ledecky, which was really exciting.

Despite her 400-metre result, Titmus cited her relay performance when she reeled in a Russian competitor as the highlight.

“I definitely felt really fast, I was mowing her down and it was a really really good swim,” she said.

“It was so cool to be standing up on the dais, because the dais was looking over the whole stadium you can see everything. It was really amazing, unlike any other medal ceremony I’ve ever had before.”
