Animals and produce-related risk: Australia New Zealand version

The Fresh Produce Safety Centre of Australia and New Zealand came out with an 8-page fact sheet on the risks of animals to fresh produce that was seven pages too long.

Chapman used to write wonderful 1-page fact sheets that were used around the world, and maybe he can be persuaded to do so again, or find a skilled student.

The important graphic is below. The rest is filler.



 

154 humans sickened from cross-contamination: FDA, CDC say US pig ear pet treat Salmonella outbreak over

This is old, but I’m playing catch-up after my medical adventures.

Being married to a veterinarian first time around, I hung out with lots of vets, who would tell me pig ear treats were potato chips for canines.

As of October 30, 2019, officials believe the Salmonella outbreak connected to pig ear pet treats seems to be over. The U.S. Food and Drug Administration (FDA) and Centers for Disease Control (CDC) started their investigation of the outbreak in July. CDC now reports that the rate of new human infections has returned to pre-outbreak, baseline levels.

“Based on the slowed rate of human illness reports, the FDA and CDC are no longer recommending that people avoid purchasing or feeding pig ear pet treats entirely,” FDA officials wrote in a press release.

At the end of July, FDA and CDC recommended no pig ear pet treat sale or use in the United States. With the end of the outbreak, the FDA altered its guidance to pet product retailers and pet owners. The agency now recommends that retailers who wish to re-introduce pig ear pet treats should take appropriate steps to ensure that their suppliers are controlling for pathogens such as Salmonella, and that products are not cross-contaminated after processing. Likewise, the agency advised pet owners to use good hygiene when feeding pig ear pet treats.

Reports of illness from these Salmonella infections started on June 10, 2015 and ran until September 13, 2019. Over the course of the outbreak, official reports tied 154 cases of human infection with exposure to pig ear pet treats in 34 states. Patients ranged in age from less than one year to 90 years. Of 133 cases with info available, 35 people needed hospitalization. Children younger than 5 years were infected in 27 cases.

Public health officials conducted genome sequencing of the Salmonella involved in the outbreak. The researchers revealed that many of the strains were resistant to multiple antibiotics, including ampicillin, streptomycin, tetracycline and ciprofloxacin. Salmonella strains identified were Cerro, Derby, London, Infantis, Newport, Rissen and I 4,[5],12:i:-.

Three firms recalled product associated with the outbreak: Pet Supplies Plus, Lennox, and Dog Goods USA. A fourth firm, Hollywood Pet, also recalled Salmonella positive pet ear treats that it had sourced from Dog Goods USA, but testing was not sufficient to determine if these treats were connected to illnesses. All of these recalled products originated from suppliers in Argentina, Brazil and Colombia. The importers were placed on Import Alert 72-03 (“Detention Without Physical Examination and Intensified Coverage of Pig Ears And Other Pet Treats Due To The Presence of Salmonella”). These importers were Suarko, SRL (Argentina) and Anabe Industria e Comercio de Proteinas (Brazil), and Custom Pet S.A.S. (Colombia).

Don’t eat dead snakes or food in containers that held dead snakes

The Hindustan Times reports at least 50 people from Odisha’s coastal Kendrapara district, most of them women and children, were taken ill after they consumed food from a container that had a dead snake in it, said an official on Thursday.

The incident happened during a community feast at Maa Shankatatarini temple in Chandan Nagar Deuli village under Pattamundai block of Kendrapara district where 30 families were having their meal. Many of the people were hospitalised after they started to vomit, said the official.

“They showed signs of food poisoning. However, many of them were discharged after administration of intravenous fluid,” said the medical officer of Pattamundai Sub Divisional Hospital, Chandra Sekhar Das. The community feast was organised by a women self help group of the area.

The presence of the dead snake was detected during the washing of the utensils.

And this is the only U2 song I can tolerate, largely because it’s rooted in a Tom Robbins novel. Otherwise, U2 is bloated and overrated.

Tennessee restaurant leaves raw frog legs above banana pudding

WATE reports a customer complaint sent a health inspector back to a Morristown restaurant six weeks after a routine inspection.

Golden Dragon, 3325 Andrew Johnson Highway, Morristown – Grade: 70

The Golden Dragon on Andrew Johnson Highway scored a 70 during the most recent inspection. The score was passing. The health department considers a grade below 70 is considered “unsanitary.”

Several of the violations marked off in the report could lead to foodborne illness if not corrected.

The inspector wrote he watched a worker carry dirty dishes from the dining room into the kitchen and start preparing food without washing his hands.

Another kitchen worker washed large containers of food in the utility sink with water and put them away without rinsing and sanitizing them.

Inside the kitchen raw frog legs were stored over banana pudding and raw fish was stored over broccoli. That is OK at home but raw food contains bacteria and placing raw food over ready to eat food raises the potential for cross-contamination.

Did health-types get it wrong or a Canberra court: Ricardo’s Café cleared of Salmonella charges

The owner of a popular Canberra cafe has had charges against him dropped, relating to a salmonella outbreak that saw more than 100 people fall ill in 2017, and has also escaped conviction on an unrelated charge.

The owner of Ricardo’s, Rick DeMarco, 32, was cleared of the most serious charges spanning from an investigation in February 2017, which began after customers complained of food poisoning on social media.

The restaurant in Jamison was immediately closed after the reports and, in a statement at the time, Mr DeMarco admitted salmonella was found on a used dishcloth and tea towel, but nothing was found in any food or on any cafe equipment.

Hello? Cross-contamination? Epidemiology?

The ACT chief magistrate Lorraine Walker did not record a conviction against De Marco, after he pleaded guilty to one count of failing to comply with the food standards code.

However, the chief magistrate said there was no correlation between Mr De Marco’s plea of guilty to the individual charge and the salmonella outbreak.

The single charge against Mr De Marco related to breaches discovered by health inspectors. These were uncovered containers of food in a refrigerator and a single-use container being reused.

However, while the food was kept inappropriately, Mr De Marco’s defence barrister Jack Pappas noted the food was kept at the required temperature in the refrigerator.

He added that Mr De Marco’s two businesses, Ricardo’s Cafe and Space Kitchen in Woden, were significant contributors to the local economy by employing about 50 people and training apprentices.

Ms Walker said that the instances were not at the lowest end of offending, “they were pretty close”.

Ms Walker said it was an instance where, due to the nature of the breach and Mr De Marco’s good character, it was appropriate to not record a conviction.

There were 75 cases of salmonella confirmed by ACT Health during the outbreak in February 2017, with some people requiring hospitalisation.

No they don’t: Netherlands study says consumers read food hygiene warning labels on poultry, and surveys still suck

Tony McDougal of Poultry World reports that researchers wanted to see how the label impacted consumer perceptions on risk and food-handling behaviour in the light that poultry meat is an important source of foodborne infections, such as campylobacter, salmonella and E.coli.

A random sample of 1235 adults from a representative internet panel received an email linking to the study questionnaire. Information was gathered about knowledge of safe food-handling regarding poultry, their current food-handling behaviour and intention to change after reading the label, as well as influencing factors.

The results, published in the October edition of the journal Food Control, found that respondents of households with people aged 65 or older, with safe food-handling practices and who judge foodborne infections as severe, were more prone to have read the label.

The study also found that after reading the label during the survey, the intention to change behaviour did not differ between the readers and previous non-readers.

The report’s authors, from the Dutch Centre for Infectious Disease Control, National Institute for Public Health and the Environment, concluded that “a label is a relatively easy and reasonable way of informing and educating consumers about safe food-handling.

“The majority of the respondents had read the label on poultry meat and scored it as important, useful and reassuring. Therefore investigating the feasibility and possible benefits of a similar label on other meat products could be worthwhile.”

The study does not account for:

the fallibility of self-reported surveys (we all wash our hands);

does  not account for multi-languages in the diverse cultures we all prepare food; does not account for cross-contamination.

Consumers should not be the CCP on your brand.

Get it together.

Delta passenger who found dog feces on his seat claims he was given two paper towels and told to clean it up himself

Delta, the airline, sucks.

That’s my experience.

Others too.

Last Thursday, a passenger onboard a Delta Airlines flight from Atlanta to Miami stepped in poop while boarding the aircraft.

Stacey Leasca of Travel and Leisure reports that according to the passenger, when he brought the feces to the crew’s attention he was reportedly handed two paper towels and told to clean it up himself.

Delta Airlines confirmed to Business Insider that passengers did indeed begin boarding the aircraft before cleaning crews were done servicing the plane. The airline also noted that during the previous flight “an ill service animal” had an incident.

“It was feces, and it was everywhere. It was on my seat. It was on the floor. My feet were in it,” passenger Matthew Meehan told WSB-TV 2 Atlanta. He explained that he stepped in fecal matter and his fellow passengers refused to sit in their seats until it was cleaned up.

But, when he asked flight attendants for supplies he was handed “two paper towels and one of those little bottles of Bombay Sapphire.” And the Delta manager wasn’t much of a help either.

“She said to me, ‘Well, that’s not my problem.’ I said, ‘I’m sorry?’ She says, ‘Well, if the cleaning crew didn’t clean your seat, I don’t have any control over that,'” Meehan explained.

In the statement, Delta additionally apologized and offered a refund and compensation to customers affected by the flight.

And now for the meaningless boilerplate quote attributed to some bureaucrat or PR flunky:“The safety and health of our customers and employees is our top priority, and we are conducting a full investigation while following up with the right teams to prevent this from happening again,” Delta Said. Upon landing, the plane was also taken out of service and has since been disinfected.

Bugs be passed around on leafy greens

Several outbreaks of foodborne illness traced to leafy greens and culinary herbs have been hypothesized to involve cross-contamination during washing and processing. This study aimed to assess the redistribution of Salmonella Typhimurium LT2 during pilot-scale production of baby spinach and cilantro and redistribution of Escherichia coli O157:H7 during pilot-scale production of romaine lettuce.

Four inoculated surrogate: uninoculated product weight ratios (10:100, 5:100, 1:100, and 0.5:100) and three inoculation levels (103, 101, and 10−1 CFU/g) were used for the three commodities. For each of three trials per condition, 5-kg batches containing uninoculated product and spot-inoculated surrogate products at each ratio and inoculation level were washed for 90 s in a 3.6-m-long flume tank through which 890 L of sanitizer-free, filtered tap water was circulated. After washing and removing the inoculated surrogate products, washed product (∼23, 225-g samples per trial) was analyzed for presence or absence of Salmonella Typhimurium or E. coli O157:H7 by using the GeneQuence Assay.

For baby spinach, cilantro, and romaine lettuce, no significant differences (P > 0.05) in the percentage of positive samples were observed at the same inoculation level and inoculated: uninoculated weight ratio. For each pathogen product evaluated (triplicate trials), inoculation level had a significant impact on the percentage of positive samples after processing, with the percentage of positive samples decreasing, as the initial surrogate inoculation level decreased.

The weight ratio of contaminated: noncontaminated product plays an important role: positive samples ranged from 0% to 11.6% ± 2.05% and from 68.1% ± 33.6% to 100% among the four ratios at inoculation of 10−1 and 101 CFU/g, respectively.

To our knowledge, this study is the first to assess the redistribution of low levels of pathogens from incoming product to leafy greens during processing and should provide important data for microbial risk assessments and other types of food safety analyses related to fresh-cut leafy greens.

Still need a better descriptor: Cross-contamination and cutting boards

Cross-contamination is one of the main factors related to foodborne outbreaks. This study aimed to analyze the cross-contamination process of Salmonella enterica serovar Enteritidis from poultry to cucumbers, on various cutting board surfaces (plastic, wood, and glass) before and after washing and in the presence and absence of biofilm.

Thus, 10 strains of Salmonella Enteritidis were used to test cross-contamination from poultry to the cutting boards and from thereon to cucumbers. Moreover, these strains were evaluated as to their capacity to form biofilm on hydrophobic (wood and plastic) and hydrophilic materials (glass).

We recovered the 10 isolates from all unwashed boards and from all cucumbers that had contacted them. After washing, the recovery ranged from 10% to 100%, depending on the board material. In the presence of biofilm, the recovery of salmonellae was 100%, even after washing. Biofilm formation occurred more on wood (60%) and plastic (40%) than glass (10%) boards, demonstrating that bacteria adhered more to a hydrophobic material.

It was concluded that the cutting boards represent a critical point in cross-contamination, particularly in the presence of biofilm. Salmonella Enteritidis was able to form a biofilm on these three types of cutting boards but glass showed the least formation.

Washing raw poultry increases cross-contamination

Campylobacter jejuni is an important human pathogen commonly associated with raw poultry. The risk of cross-contamination in the kitchen is escalated with washing raw poultry in the sink- an unnecessary measure for food safety. Cook the bird to an internal temperature of 74°C (165°F), no need for washing.

Holly Van Hare of The Daily Meal reports:

You’re spraying your sink with salmonella
Washing your fruit? Absolutely. Washing your lettuce? Necessity. But running warm water over a slimy slab of raw chicken is just about the worst thing you can do with your kitchen sink.
In fact, it’s such a bad idea that the National Health Service (NHS) in Britain issued a public warning against the “sanitary” practice — claiming that “it can increase your risk of food poisoning from campylobacter bacteria.”
Chicken is one of the most commonly infected raw foods when it comes to foodborne bacteria such as salmonella. These bacteria lurk both on the surface and insides of the raw meat, growing indefinitely until you cook them dead. “Only a few campylobacter cells are needed to cause food poisoning,” the NHS says.
Washing the chicken involves running tap water over that infested piece of meat. The water becomes contaminated as soon as it hits the surface of your poultry, and proceeds to splash in every direction both inside and around your kitchen sink. “Water droplets can travel more than 50 centimeters in every direction,” the NHS warns, a distance that equates to over one and a half feet.
After that bacteria spreads, it’s hard to get rid of. The only real way to effectively kill the bacteria you’ve now sprinkled around your home is to disinfect everything — an onerous task you’re likely saving until after you’re done cooking. That means your risk of exposure is prolonged and the bacteria could even come into contact with your other food.
If you’re preparing chicken, skip the washing step. The oven kills everything, anyway — and once a chicken is properly cooked, it’s 100 percent free of disease-causing bacteria. If you’re bored with bland old chicken and looking to spice things up, here are 101 of our best recipes.
