An emerging pathogen: Helicobcter pullorum in chicken

Meat and meat products are important sources of human intestinal infections. We report the isolation of Helicobcter pullorum strains from chicken meat.

icarly.chicken.handsBacteria were isolated from 4 of the 17 analyzed fresh chicken meat samples, using a membrane filter method. MIC determination revealed that the four strains showed acquired resistance to ciprofloxacin; one was also resistant to erythromycin, and another one was resistant to tetracycline. Whole-genome sequencing of the four strains and comparative genomics revealed important genetic traits within the H. pullorum species, such as 18 highly polymorphic genes (including a putative new cytotoxin gene), plasmids, prophages, and a complete type VI secretion system (T6SS). The T6SS was found in three out of the four isolates, suggesting that it may play a role in H. pullorum pathogenicity and diversity.

This study suggests that the emerging pathogen H. pullorum can be transmitted to humans by chicken meat consumption/contact and constitutes an important contribution toward a better knowledge of the genetic diversity within the H. pullorum species. In addition, some genetic traits found in the four strains provide relevant clues to how this species may promote adaptation and virulence.

FDA in India shuts down Agaccaim bakery

The directorate of food and drugs administration (FDA) on Friday raided a bakery at Agaccaim for supplying ‘stale’ chicken rolls that were ordered for a religious function at Sodovim-Verna. After consuming the rolls, several people had taken ill as a result of food poisoning.

CCP-150x150FDA director Salim Veljee informed that the officials visited the bakery on Friday morning and found that it was being operated under unhygienic conditions and there was no proper facility for storing raw material and the same was kept on the floor.

“The owner of the bakery admitted to having supplied the food items for a religious function at Sadovim in Verna,” stated Veljee adding, the bakery owner was immediately directed to shut it down till all the defects observed by the food safety officers are rectified and verified by the office of the directorate of food and drugs administration.

“The food and drugs administration officials collected samples of egg patties, cakes as well as chicken rolls and the same were sent to the laboratory for microbiological analysis. Further action can be initiated only after the receipt of the microbiological analysis of the samples sent by the police as well as the FDA officials,” Veljee said.

Modeling toxo in meat

Toxoplasma gondii is a protozoan parasite that is responsible for approximately 24% of deaths attributed to foodborne pathogens in the United States.

doug.cats.jun.14It is thought that a substantial portion of human T. gondii infections is acquired through the consumption of meats. The dose-response relationship for human exposures to T. gondii-infected meat is unknown because no human data are available. The goal of this study was to develop and validate dose-response models based on animal studies, and to compute scaling factors so that animal-derived models can predict T. gondii infection in humans. Relevant studies in literature were collected and appropriate studies were selected based on animal species, stage, genotype of T. gondii, and route of infection. Data were pooled and fitted to four sigmoidal-shaped mathematical models, and model parameters were estimated using maximum likelihood estimation. Data from a mouse study were selected to develop the dose-response relationship.Exponential and beta-Poisson models, which predicted similar responses, were selected as reasonable dose-response models based on their simplicity, biological plausibility, and goodness fit. A confidence interval of the parameter was determined by constructing 10,000 bootstrap samples. Scaling factors were computed by matching the predicted infection cases with the epidemiological data. Mouse-derived models were validated against data for the dose-infection relationship in rats. A human dose-response model was developed as P (d) = 1–exp (–0.0015 × 0.005 × d) or P (d) = 1–(1 + d × 0.003 / 582.414)−1.479. Both models predict the human response after consuming T. gondii-infected meats, and provide an enhanced risk characterization in a quantitative microbial risk assessment model for this pathogen.

FDA orders Idaho juice company to shut down

The U.S. Food and Drug Administration has ordered a juice company in Ketchum to halt operations after concerns that it was violating food safety laws.

Sun Valley Juice CompanyThe Sun Valley Juice Company is barred from receiving, processing, preparing, packing, holding, or distributing juice until the FDA finds that the company is following federal laws and regulations. Sun Valley Juice Company has complied with the demand to shut down.

The company’s website advertises “freshly squeezed orange and grapefruit juice.” No one answered the phone at the company Friday.

According to the FDA, the company has repeatedly violated the Federal Food, Drug and Cosmetic Act and terms of a consent decree put in place by a judge in 2006. As part of the court-ordered agreement between the company and the FDA, the Sun Valley Juice Company agreed to put a hazard prevention plan in place. The consent decree was part of repeated attempts to help the company come into compliance before the shutdown, according to the FDA.

Because the company does not pasteurize its juice, it has to follow other regulations to ensure its juice is safe to drink and not contaminated with harmful bacteria. Pasteurization is a process that kills the bacteria leading to illness like E. coli.

Sun Valley Juice Company will not be allowed to reopen until FDA inspectors are satisfied its products are safe and that the company will follow safety laws.

And now, a Chipotle update: 22 sick from E. coli as Chipotles close in Ore., Wash. amid investigation

A number of Chipotle restaurants across the Northwest abruptly closed late Friday afternoon.

portland-press-herald_3512878On Saturday morning, the Oregon Health Authority said they were investigating a possible E. coli outbreak at Oregon and Washington Chipotles. Three cases in Oregon and 19 in Washington were reported, and one-third of those people were hospitalized, according to OHA spokesman Jonathan Modie.

People in Clackamas and Washington counties in Oregon, and Clark, King, Skagit and Cowlitz counties in Washington have reported symptoms of Shiga toxin E. coli (STEC) infection, according to the OHA.

Chipotle released the following statement Saturday and said all stores near where the illnesses were reported were temporarily closed.

“The safety and wellbeing of our customers is always our highest priority. After being notified by health department officials in the Seattle and Portland, Ore. areas that they were investigating approximately 20 cases of E. coli, including people who ate at six of our restaurants in those areas, we immediately closed all of our restaurants in the area out of an abundance of caution, even though the vast majority of these restaurants have no reported problems. We are working with health department officials to determine the cause of this issue. We offer our deepest sympathies to those who have been affected by this situation.” 

Chipotle restaurants from the Portland metro area all the way up to Seattle closed their doors. Adding to the mystery were the signs found on the doors.

“We’re sorry for the inconvenience and sincerely hope that you’ll enjoy the day no matter what you may be observing,” read the sign posted at the PSU Chipotle.

“Don’t panic … due to an equipment issue we are unable to open at this time … order should be restored to the universe in the very near future,” read the sign posted at the Chipotle in Northwest Portland.

5 sick with E. coli: Chipotle still sucks at food safety

The Skagit County Department of Public Health in Washington state announced Friday that it has closed Chipotle Mexican Grill in Burlington pending an investigation of several E. coli infections among recent diners.

chipotle.ad.2Of five cases under investigation since Oct. 15, four individuals were hospitalized, according to the health department news release. Results of specimens sent to the state health lab for analysis are expected early next week.

‘I work for the public to make sure their dining experience is not going to send them to the hospital’

CBC News reports that food kept too warm or too cold, dirty utensils and one live animal have all been found in Windsor and Essex County restaurants within the past year, according to a CBC News analysis of Windsor-Essex County Health Unit reports (that’s in Ontario, Canada).

Documents provided to CBC News by the health unit show 1,795 health and safety infractions at 540 locations where food was served between Oct. 2014 and 2015.  

The health unit regularly inspects restaurants and places where food is served in Windsor and Essex County. The frequency of the inspections depends on how high the risk is for food contamination at each place.  According to the health unit, a full-service restaurant is inspected at least three times a year.

“We are enforcers, but we’re trying to educate first,” Elaine Bennett, a public health inspector with the health unit said in an interview with CBC News. “We’re working with people to make sure they’re not causing food-borne illness in the community.”

Bennett has been a health inspector for the past 15 years.

“Ultimately I’m working for the public to make sure their dining experience is not going to send them to the hospital,” she said.  

 

Muesli recalled in UK

I usually begin my day about 3 a.m. (Australian time, that’s 1 p.m. EST) with a review of news, a couple of interviews, and a bowl of homemade granola (I use Alton Brown’s recipe), yogurt, and frozen berries that had been microwaved the night before and then sat in the fridge overnight to reduce the risk of hepatitis A.

Cow & Gate in the UK is recalling one batch of its Sunny Start My First Banana Muesli from 10 months on a precautionary basis because of complaints regarding insects found in the product. The company has advised that this product should not be consumed, in case other packs in the batch are affected.

I also like to begin my day with music while I write, and today in 1971, Pink Floyd released Meddle, a vastly underrated album but one that showed the potential of an evolving band that led to Dark Side of the Moon in 1972.

Important: Explaining Canadian food law and staying out of jail

Ronald L. Doering, a past president of the Canadian Food Inspection Agency and currently counsel in the Ottawa offices of Gowling (Ronald.doering@gowlings.com) writes:

Chance_go_to_jailFood company owners and managers are increasingly at risk of being taken to criminal court to face huge fines and imprisonment, even if they didn’t mean to do anything wrong, didn’t know they were doing anything wrong, or didn’t know that an employee was committing a prohibited act.

Everyone knows it’s a crime to sell unsafe food or mislabelled product, but there are many hundreds of other crimes in our food laws. Moreover, most of these offences are strict liability offences, which means that the Crown must only establish the criminal act; there is no need to prove that the accused intended or allowed the prohibited act to occur, even if the occurrence was totally accidental.

In Canada there is a defence to strict liability offences, a defence that deserves to be better known. In the leading case of R. v. Sault Ste. Marie, the Supreme Court of Canada recognized that in the case of strict liability offences “the accused can avoid liability by proving that he took all reasonable care; the defence will be available if the accused reasonably believed in a mistaken set of facts which, if true, would render the act or commission innocent, or if he took all reasonable steps to avoid the particular event.” Both branches of the defence turn on the notoriously vague concept of reasonableness.

There are several reported cases in environmental law and occupational

 health and safety law that help to define the scope of the defence, but there are very few that deal with food legisla­tion. Since 1992 it is settled law that the defence is available to charges under our Food and Drugs Act (FDA) but there are only three relevant cases to provide practical guidance to the industry. In HMTQ v. Stars Trading Co. (2003 BCSC 833) the company was selling imported coconut juice from Thailand to supermarkets in Canada without listing on the label that it contained sulphites, a potential allergen.

The accused argued the due diligence defence by claiming that it had received assurances from the exporter that the juice was sulphite free. The Canadian Food Inspection Agency (CFIA) had previously warned the company that it should test the product and the company had a history of non-compliance with the FDA. After a good review of the law, the Court held that the accused had not taken all reasonable care and therefore could not rely on the due diligence defence.

ron.doeringIn R. v. Can-na Foods-2 Ltd., Tran Quyen Luu, Jane Jay et al. (2003 ABQB 758) the accused meat manager Luu and the owner Jay were charged with selling horse meat as beef. The court held that all reasonable steps to determine the source of the meat had not been taken  and therefore the due diligence defence was not available. Heavy fines were imposed on the company, the employee and the owner.

In R. v. Ray’s Seafood Market the CFIA charged the accused with seven counts under the Fish Inspection Act of importing fish into Canada without an import licence. Both the trial judge and the Supreme Court judge accepted Ray’s due diligence defence, but the Quebec Court of Appeal quashed the acquittal and ordered a new trial, concluding that Ray’s excuse was es­sentially ignorance of the law, something that is never a defence.

The most significant new development in our law is the passage (though not yet proclaimed) of the Safe Food for Canadians Act. Under section 39 (1) the accused is liable on indictment to a fine of not more than $5 million or to imprisonment for a term of not more than two years or to both, but the person is not to be found guilty “if they establish that they exercised due diligence to prevent the commission of the offence.” The message for owners and senior managers is clear: a strong food safety culture passionately driven from the top down was always necessary to avoid recalls and protect the brand name. Exceeding standards and taking all preventative measures may also be the best way to stay out of jail.
