‘Dad a chick pooped on me’

Scott Weese of the Worms and Germs Blog, a prof, vet, from the University of Guelph, and more importantly, a dude I played hockey with all those years ago, writes, as I was writing the post below, my youngest daughter walked in the door and said “a chick pooped on me today.”

(He’s one of the bald dudes in this pic from 2005: hint, leave when you’ve won, and have a full head of hair, which I did)

It wasn’t a total surprise since I’d heard a vague statement from her about maybe having chicks in the class for the end of the year.

Is it potentially fun and/or educational?

Sure. If it’s done right.

Is it done right?

Doesn’t sound like it.

Chicks are cute and can be entertaining. They can also be educational. Yet, contact with them is clearly associated with disease. While I get an infosheet from the school and have to sign something every time one of my kids does any other type of activity, there was no notice about this particular activity, no information about risks and preventive measures, nothing about what to do if a child is at high risk for severe disease, or anything else.

Just my kid telling me she got pooped on.

I’m not overly concerned. She’s healthy, outside of the main high risk groups, and washed her hands after the incident. Yet, I don’t know (and doubt the school knows) whether that applies to everyone in the class or other kids that might have contact with the chicks. The chicks are also being kept in a classroom where the students eat.

A lot could be done to minimize and communicate the risks. We tried approaching the provincial Ministry of Education and school boards quite a few years ago to look into animal exposures in schools, and there was basically zero interest in the subject. Whether that’s because there was no awareness of the issues or no desire to find out what’s actually going on is hard to say.

Now on to the post I was writing…

CDC has related an updated investigation notice about Salmonella from backyard poultry. As of June 13th, 279 infected people have been identified in 41 states, with cases dating back to January 1st, 2019.. That probably means a few thousand people have actually been infected, since reported disease numbers are typically dwarfed by the real number of cases.

The strains that have been linked to the outbreak are Salmonella Agona, Anatum, Braenderup, Infantis, Montevideo and Newport

30% of infected people were children younger than 5 years old, which is the group that typically gets sick or seriously ill from Salmonella.

26% of people were hospitalized. Fortunately, no deaths were reported.

About 40% of isolates were multidrug-resistant.

77% of infected individuals reported contact with chicks or ducklings from places like agricultural stores, mail order supplies and hatcheries.

One of the outbreak strains has also been found in backyard poultry in Ohio.

I’m not against animals in schools or backyard poultry. I’m just against being stupid. There are lots of things that can be done to reduce risks, and too often those easy, cheap and practical measures are ignored.

Frank talks about sprouts

Frank didn’t waste any time after leaving Wal-Mart for government.

Good on ya.

But guidance is not enforcement.

My group learned that the hard way 20 years ago.

And they still serve sprouts to immunocompromised people in Australian hospitals despite a ridiculous number of outbreaks.

“Over the past 22 years, the U.S. Food and Drug Administration (FDA) has investigated 50 reported outbreaks of foodborne illness associated with contaminated sprouts. Together, these outbreaks resulted in more than an estimated 2,600 cases of illness. Last year, there were two reported outbreaks associated with sprouts, resulting in more than an estimated 100 illnesses. Studies indicate that contaminated seed is the likely source of most sprout-related outbreaks, as this commodity is inherently more susceptible to these issues because they are grown in warm and humid conditions that are favorable for bacteria like Salmonella, Listeria and E. coli,” said FDA Deputy Commissioner for Food Policy and Response Frank Yiannas.

“The FDA is committed to taking swift action to respond to outbreaks related to sprouts and keep our food supply safe, but we also know that measures to prevent issues from happening in the first place are an important element of protecting consumers. By studying outbreaks related to sprouts over the years, we have been able to recommend changes in the industry to help lower the incidence of sprout-related outbreaks. Today’s new draft guidance is another critical step, like the Sprout Safety Alliance or sprout-specific requirements of the Produce Safety Rule, the agency is taking to prevent illnesses related to sprouts.”

FDA today released a proposed draft guidance, “Reducing Microbial Food Safety Hazards in the Production of Seed for Sprouting,” intended to make the sprout seed industry (seed growers, conditioners, packers, holders, suppliers, and distributors) aware of the agency’s serious concerns with the continuing outbreaks of foodborne illness associated with the consumption of raw and lightly-cooked sprouts.

Incorporating aspects of the Codex Code of Hygienic Practice for Fresh Fruits and Vegetables Annex II, Annex for Sprout Production; the International Sprout Growers Association-Institute for Food Safety and Health’s “U.S. Sprout Production Best Practices”; and Good Agricultural Practices, the FDA’s draft guidance issued today provides the agency’s recommendations to firms throughout the production chain of seed for sprouting. It states that if a grower, holder, conditioner, or distributor reasonably believes that its seeds are expected to be used for sprouting, we recommend that the grower, holder, conditioner, or distributor take steps that are reasonably necessary to prevent those seeds from becoming contaminated. We also recommend that firms throughout the supply chain – from seed production and distribution through sprouting – review their current operations related to seeds for sprouting.

During the 60-day comment period for this draft guidance, stakeholders will be able to provide comments on the draft provisions. For more information on this guidance, as well as instructions on how to submit your comments, please visit Draft Guidance for Industry: Reducing Microbial Food Safety Hazards in the Production of Seed for Sprouting.

Happy birthday, Amy Hubbell

Happy birthday to my beautiful and brainy wife who has guided me through the last few years as my brain goes away, is manager of Sorenne’s hockey team, and has taken on a lot that she didn’t sign up for.

(She’s driving me to the neurologist in about an hour).

This pic is shortly after we met in 2005.

She’s wearing her trademarked, I’m-a-French-professor-so-I-get-to-wear-outrageous-scarfs look, and I’m wearing a shirt from the long gone New Zealand Food safety Authority.

NZ mussels at centre of food poisoning outbreak

Seafood lovers have been warned to be careful with raw mussels after an outbreak of food poisoning.

New Zealand Food Safety announced on Friday it’s seen an uptick in the number of people contracting food poisoning from Vibrio parahaemolyticus.

Most of the people who got sick ate commercial grown mussels harvested in Coromandel.

“It is possible that the strain of vibrio parahaemolyticus is unusually aggressive, which may mean that even low numbers could cause illness,” NZ food safety director of regulation Paul Dansted said.

“Additional testing of mussels and the waters that they are being grown in is also underway to help us understand why this has happened.

“The mussels at the centre of the outbreak were all bought in their raw state, in the shell. They are not the mussels that can be bought in plastic pottles. Those mussels are cooked and marinated and are not affected.”

NZ Food Safety says people need to be careful when cooking mussels and heat them above 65C. It’s also advised to wash hands after handling shellfish, and avoid cross-contamination between raw and cooked shellfish.

Informational nudges shaping food safety perceptions

The study examines the influence, and potential confluence, of message framing and issue involvement on consumer food safety perceptions. We assess the impact of gain and loss-framed messages and issue involvement on perceptions of two food safety enhancing technologies, cattle vaccines against E. coli and direct-fed microbials.

A survey with six information treatments was developed. Empirical results show that both loss-framed and gain-framed messages were persuasive in influencing safety perceptions of the two technologies under low issue involvement. Under high issue involvement, however, only the loss-framed message influenced consumers’ safety perceptions. High issue involvement also heightened concerns about foodborne infections.

iPhone lost for 18 months found

About 18 months ago, I sat on a bench in Brisbane and my iPhone 7 fell out of my pocket.

Someone picked it up.

Two nights ago the Queensland police e-mailed me and said they found it.

We had traced the phone using findmyphone, but it was an apartment complex about 2 km away and couldn’t get a specific signal.

I had filed a police report with the serial number, but insurance wouldn’t cover it, so I figured it was just another technology tragedy (also why I use a computer from 2012 because I’ll just drop it, why I used an iPhone 5 for years, because I’d just drop it, why I have to concentrate when I walk, because I’ll just fall over).

And then, after 18 months, the phone shows up at the West End police station.

They wouldn’t or couldn’t tell me how they came into possession of it, my beautiful wife drove me to the police station, and daughter Sorenne now has a nice upgrade to her iPhone 5.

And since this is personally weird post, here’s a picture of when I was about 3 on Grandpa Homer’s tractor (the asparagus baron) that my mother sent along. She’s 77 and flying to Australia to be with me for a week.

 

 

US study charts changes in food safety practices

Tom Karst of The Packer writes U.S. growers are using less risky irrigation sources and are sanitizing their equipment more often than 20 years ago. 

Geez that’s about how long my group was doing on-farm food safety and looking at those exact questions.

Guess on-farm food safety is just a John Prine song.

Those observations are part of a new study called “Changes in U.S. Produce Grower Food Safety Practices from 1999 to 2016,” authored by economists Gregory Astill, Travis Minor and Suzanne Thornsbury.

The study is available online without cost until July 5.

“Since 1999, and before the implementation of U.S. Standards for the Growing, Harvesting, Packing, and Holding of Produce for Human Consumption, the share of growers who use practices that reduce the risk of microbial contamination increased,” the study concluded.

The study said fewer growers use flowing surface water for irrigation and more growers use well water. As organic production has increased over time, the study found that more growers use manure and compost. And while more growers’ fields are next to livestock, the authors said more growers use fencing around production areas.

“The most prominent example of change is the increase in frequency that growers and sanitize harvest tools,” the study said. “The decrease in growers who never wash harvest tools is drastic as is the decrease in those who never sanitize.” 

Even with the increase in food safety practices, the study said more needs to be done.

“The data available for this article also demonstrates a real need to implement more frequent measures of food safety practices within this rapidly evolving industry,” the authors said.

Piping hot is stupid cooking advice, that only the Brits could have come up with

I take pride in my Birmingham and Newport, Wales roots, as well as a lot of Ontario (that’s in Canada) but the UK government’s continued insistence that food be cooked to piping hot is not only unscientific, but just stupid.

This paper sounds nice, but will have no effect.

Chapman, I never got those Comarks, and need about 100 so I can keep improving food safety, one tip-sensitive digital thermometer at a time.

Improper cooking of meat contributes to many foodborne illnesses worldwide. The use of meat thermometers during cooking is recommended by food safety authorities in North America, but not yet in Europe. This scoping review investigated meat thermometer usage trends, consumers’ barriers and facilitators, and usage-enhancing interventions, with the aim of informing potential policy changes as necessary towards enhancing meat thermometers usage.

The study revealed that Europe is far behind North America in meat thermometer research and consumer use. The study results highlighted the increased compliance among mid-aged and higher socio-economic consumer groups. A considerable percentage of people do not use a meat thermometer, despite owning one and knowing its importance.

Barriers to meat thermometer usage among consumers included: cooking habits, non-practicality, and the influence of society and media, whereas responsibility to dependents and enhancing meat quality were strong facilitators. Intervention studies showed that knowledge gain does not necessarily translate to behavior change, unless consumers’ barriers and facilitators are addressed; hence behavioral theory-based interventions were most effective. The review concludes with recommendations for food safety authorities, starting with filling the research gap to understand consumers’ attitudes and behaviors, followed by implementation and scaling-up of evidence-based interventions, associated with cost-effectiveness studies.

Is scoping now a cool word?

Dining in Finland

Readers know I’m a fan of restaurant inspection disclosure results, and now, so is Finland.

Disclosure systems for official food safety inspection results have been introduced in many countries including Finland in order to increase compliance of food business operators (FBOs). Although the disclosure systems are intended to affect FBOs, few studies have been published on FBOs’ experiences of these systems.

To investigate FBOs’ opinions of disclosed food safety inspections in Finland, a questionnaire was distributed in 2016. The questionnaire study also aimed to recognize factors affecting compliance and disagreements about gradings with a special focus on FBOs’ risk perception. In total 1277 responses from FBOs in retail (n=523), service (n=507) and industry (n=247) sectors revealed that the majority of FBOs perceived the disclosure to promote correction of non-compliance. However, many FBOs disagreed with the grading of inspection findings.

Most common topics of disagreements were maintenance of premises, record-keeping of own-check plan and adequacy and suitability of premises for operations. Logistic regression analysis showed that the likelihood of occurrence of disagreements with grading was higher among those retail and service FBOs with a lower risk perception. Similarly, the occurrence of non-compliance was associated with FBOs’ risk perception in all sectors. Thus, FBOs need proper guidance on food safety risks. These results can be used to improve the efficacy of disclosed food safety inspections.

‘My family could have died’ Gold Coast man realizes his half-eaten McDonald’s chicken burger is raw after stopping to look at the pink and slimy meat

I always prefer the data of a thermometer, but yeah, this looks raw.

Gold Coast, Australia man has been left outraged after biting into a McDonald’s chicken burger only to find it was still raw half way through eating it.

Joseph Kim took to Facebook on Saturday to share photos of the uncooked burger which he claims could’ve potentially harmed him and his whole family.

Mr Kim said his daughter and wife had delivered his meal to his job after picking up lunch for their family at McDonald’s in Upper Coomera.

At first glance, he noticed his Chicken Crispy Clubhouse burger hadn’t been assembled properly, but didn’t think anything of it.   

Mr Kim proceeded to ‘dive’ right into his meal, getting half way through his burger before making the stomach-churning discovery

In a statement to the Gold Coast Bulletin, a McDonald’s spokesperson said they were ‘disappointed’ over the incident, while adding: ‘We take food safety very seriously and have strict processes and systems in place.’
