Research – EU Commission notice on guidance document on addressing microbiological risks in fresh fruits and vegetables at primary production through good hygiene – 2017

EUR LEX

Norovirus Food Safety kswfoodworld

According to the 2014 Zoonosis Monitoring Report (1), the majority of verified outbreaks in the EU were associated with foodstuffs of animal origin. Fruit and vegetables were implicated in only 7,1 % of the verified outbreaks, primarily caused by frozen raspberries contaminated with Norovirus, albeit showing an increase compared to 2013 where ‘vegetables and juices’ were reported in 4,4 % of the outbreaks.

Nevertheless, the possible consequences of microbiological contamination of fresh fruits and vegetables (FFV) cannot be under­estimated as shown by the German crisis (2) linked to the contamination of sprouts by Verotoxin-producing Escherichia coli (VTEC).In the aftermath of this VTEC crisis in 2011, the Commission asked the European Food Safety Authority (EFSA) to advice on the public health risks posed by pathogens in food of non-animal origin (FNAO), addressing in particular the risk factors and the mitigation options including possible microbiological criteria.

As a result, EFSA issued six scientific opinions on the following food/pathogen combinations identified as the most important risks within FNAO:

1) VTEC in seeds and sprouted seeds

(2) Salmonella and Norovirus in food of leafy greens eaten raw as salads.

(3) Salmonella and Norovirus in berries.

(4) Salmonella and Norovirus in tomatoes.

(5) Salmonella in melons.

(6) Salmonella, Yersinia, Shigella and Norovirus in bulb and stem vegetables, and carrots.

This guideline takes account of the relevant opinions of EFSA, and consultation with Member States experts and relevant stakeholders. Though it is intended to offer practical help to growers, it may also be used by official inspectors during their audits where appropriate. EFSA confirmed that further research on possible risks and risk mitigating measures related to FFV should continue.

Research – Effect of phenolic compounds and cold shock on survival and virulence of Escherichia coli pathotypes

Wiley Online

Phenolic compounds (PC) affect many metabolic processes of microbes; however, there is no information about their effectiveness when these act in combination with low temperatures for the control of Escherichia coli pathotypes. In this study, four PC, (tannic acid [TA], gallic acid [GA], methyl gallate [MG], and epigallocatechin gallate [EG]) in combination with cold shock (CS, 10°C) were evaluated for their effect on growth, swarming motility, biofilm formation, and expression of selected virulence-related genes of E. coli pathotypes [enteropathogenic (EPEC), enterohemorrhagic (EHEC), and enterotoxigenic (ETEC)]. Sub-inhibitory concentrations of the PC were used alone (37°C) or in combination with CS. For CS assays, E. coli strains were grown at 37°C until mid-log phase and then subjected to 10°C for 4 hr. Membrane damage was determined by flow cytometry; swarming motility was measured on soft-LB agar, biofilm formation was analyzed by crystal violet staining, and gene expression of CS, biofilm, and swarming motility related-genes was determined by qPCR. Sub-inhibitory concentrations of the PC did not affect the viability of the strains. The combination of CS + TA provoked the highest (p ≤ .05) mortality in all pathotypes. CS + GA inhibited (100%) the motility of EHEC and ETEC. PC and CS + PC reduced (p ≤ .05) biofilm formation. The combination of PC and CS affected virulence factors and their gene expression of pathogenic E. coli presenting a novel alternative for its control in foods.

Research – First E. coli O103 outbreak caused by minced raw celery gets review.

Food Safety News

E. coli O103, one of the more rare Shiga-toxin producing E. coli, sickened patients at two Victoria, British Columbia, hospitals last April. The Vancouver Island outbreak is now the subject of a study on food safety for high-risk products prepared for vulnerable populations.

Based on confirmed E. coli O103 cases reported to the Island Health infectious disease unit, whole-genome sequencing was used in the case study. The Canada Communicable Disease Report (CCDR) published the study in its January 2022 edition.

The Victoria outbreak identified six confirmed E.coli O103 cases, with 67 percent being female and a medium age of 61. All were inpatients or outpatients at the two hospitals. All consumed raw minced celery sandwiches prepared by the hospital food services.

Investigation summary

As of January 28, there have been 14 laboratory-confirmed cases of E.coli O157 illness linked to this outbreak in the following provinces: Alberta (13) and Saskatchewan (1).

Individuals became sick between early December 2021 and early January 2022. No deaths or hospitalizations have been reported. Individuals who became ill are between 0 and 61 years of age. The majority of cases (64%) are female.

The CFIA issued a food recall warning on January 28 for certain Hankook (Korean characters only) brand Kimchi products. The recalled product wasdistributed in British Columbia, Alberta, Saskatchewan, and Manitoba.

The CFIA is continuing its food safety investigation, which may lead to the recall of other products. If other products are recalled, the CFIA will notify the public through updated food recall warnings.

Who is most at risk

E. coli O157 is more likely to cause severe illness than other strains of E. coli. Pregnant women, those with weakened immune systems, young children and older adults are most at risk for developing serious complications.

Most people who become ill from an E. coli infection will recover completely on their own. However, some people may have a more serious illness that requires hospital care or causes long-lasting health effects. In rare cases, some individuals may develop life-threatening complications, including stroke, kidney failure and seizures, which could result in death. It is possible for some people to be infected with the bacteria and to not get sick or show any symptoms, but to still be able to spread the infection to others.

What you should do to protect your health

The following advice applies to individuals, as well as retailers, distributors, manufacturers and food service establishments such as hotels, restaurants, cafeterias, hospitals and long-term care homes, across Canada:

  • Do not eat, use, sell or serve the recalled kimchi or any products made with the kimchi. Check to see if you have recalled food products at home. If you do, throw them out and wash your hands.
  • Clean and sanitize all surfaces and storage areas that recalled kimchi or any products made with the recalled kimchi may have come in contact with, including countertops, containers, utensils, freezers, and refrigerators.
  • If you have been diagnosed with an E. coli infection or any other gastrointestinal illness, do not cook food for other people.

Symptoms

People infected with E. coli can have a wide range of symptoms. Some do not get sick at all, though they can still spread the infection to others. Others may feel as though they have a bad case of upset stomach. In some cases, individuals become seriously ill and must be hospitalized.

The following symptoms can appear within one to ten days after contact with the bacteria:

  • nausea
  • vomiting
  • headache
  • mild fever
  • severe stomach cramps
  • watery or bloody diarrhea

Most symptoms end within five to ten days. There is no real treatment for E. coli infections, other than monitoring the illness, providing comfort, and preventing dehydration through proper hydration and nutrition. People who develop complications may need further treatment, such as dialysis for kidney failure. You should contact your health care provider if symptoms persist.

What the Government of Canada is doing

The Government of Canada is committed to protecting the health of Canadians from enteric disease outbreaks.

PHAC leads the human health investigation into an outbreak and is in regular contact with its federal, provincial and territorial partners to monitor the situation and to collaborate on steps to address an outbreak.

Health Canada provides food-related health risk assessments to determine whether the presence of a certain substance or microorganism poses a health risk to consumers.
CFIA conducts food safety investigations into the possible food source of an outbreak.

Epidemiological information

Figure 1 is an epidemiological curve for this outbreak, which shows the numbers of new cases by week. Outbreak investigators use this information to show when illnesses begin, when they peak, and when they trail off. It can take several weeks from the time a person becomes ill to when the illness is reported and testing confirms a link to the outbreak. Data are available for 14 cases.

Research – Wild Boars as Reservoir of Highly Virulent Clone of Hybrid Shiga Toxigenic and Enterotoxigenic Escherichia coli Responsible for Edema Disease, France

CDC

Edema disease is an often fatal enterotoxemia caused by specific strains of Shiga toxin–producing Escherichia coli (STEC) that affect primarily healthy, rapidly growing nursery pigs. Recently, outbreaks of edema disease have also emerged in France in wild boars. Analysis of STEC strains isolated from wild boars during 2013–2019 showed that they belonged to the serotype O139:H1 and were positive for both Stx2e and F18 fimbriae. However, in contrast to classical STEC O139:H1 strains circulating in pigs, they also possessed enterotoxin genes sta1 and stb, typical of enterotoxigenic E. coli. In addition, the strains contained a unique accessory genome composition and did not harbor antimicrobial-resistance genes, in contrast to domestic pig isolates. These data thus reveal that the emergence of edema disease in wild boars was caused by atypical hybrid of STEC and enterotoxigenic E. coli O139:H1, which so far has been restricted to the wildlife environment.
