Research – Ten years of molecular epidemiology surveillance of Listeria monocytogenes in Chile 2008–2017.

Science Direct

Highlights

Listeria monocytogenes is an emerging foodborne pathogen in Chile.

Serotypes 1/2a, 1/2b and 4b were the most frequently detected in food products.

Some L. monocytogenes clonal populations are persistent and widespread in foods.

Genomic diversity of this pathogen in foods is considerable and change over time.

Abstract

Listeria monocytogenes causes severe diseases in humans, including febrile gastroenteritis and systemic infections that has a high mortality despite antibiotic treatment. This pathogen may cause massive outbreaks associated to the consumption of contaminated food products, which highlight its importance in public health. In the last decade, L. monocytogenes has emerged as a foodborne pathogen of major importance in Chile. A previous work showed that in Chile during 2008 and 2009, L. monocytogenes serotypes 1/2a, 1/2b and 4b were the most frequently identified in food and clinical strains. Here we report the molecular characterization of L. monocytogenes strains isolated from 2008 to 2017 in the country. Our results indicate that serotypes 1/2a, 1/2b and 4b continue to be the most commonly found in food products. In addition, we identify persistent and widespread PFGE subtypes. This study reports ten years of epidemiological surveillance of L. monocytogenes in Chile.

Research – Norovirus most often responsible for foodborne outbreaks in Finland

Food Safety News norovirus-1080x655

More than 130 foodborne outbreaks were recorded in Finland between 2014 and 2016, according to a recent report.

Data comes from a register of foodborne and waterborne outbreaks maintained by the former Finnish Food Safety Authority (Evira) that became the Finnish Food Authority (Ruokavirasto) at the beginning of this year.

The number of people infected from foodborne pathogens was 2,761 in 132 outbreaks. Forty-eight people needed hospital treatment. No deaths were reported.

Vegetables and meat common food sources
Norovirus remained the most common agent in foodborne outbreaks between 2014 and 2016. It was responsible for 42, or 32 percent, of such outbreaks.

Philippines – Hundreds hospitalized with suspected food poisoning during Marco’s birthday party

Outbreak News Today

More than 300 people have been hospitalized due to suspected food poisoning during the 90th birthday celebration of Imelda R. Marcos, the former first lady of the Philippines, according to Philippines news sources.

According to Health Secretary Francisco Duque III, 306 are still admitted in the hospital. He went on to say that 149 have been discharged while the rest are still under observation or admitted in the hospital.

The patients “suffered from vomiting and dizziness,” said Richard Gordon, the chairman of the Philippine National Red Cross, which deployed emergency teams to the Ynares Sports Complex east of Manila where the party was held.

Mr. Gordon, who is also a Philippine senator, said hundreds of the estimated 2,000 people at the event apparently became ill after eating chicken adobo, rice and eggs.

USA – Outbreak of Salmonella Infections Linked to Karawan brand Tahini

This outbreak appears to be over, but recalled tahini products have a long shelf life and may still be in people’s homes. Consumers unaware of the recall could continue to eat these products and potentially get sick. Visit the FDA websiteexternal iconfor a full list of recalled products.

Final Outbreak Information
Illustration of a megaphone.
  • As of June 26, 2019, this outbreak appears to be over.
  • A total of 6 people infected with the outbreak strain of Salmonella Concord were reported from 3 states.
    • Illnesses started on dates ranging from March 9, 2019, to May 2, 2019.
    • One hospitalization and no deaths were reported.
  • Epidemiologic, traceback, and laboratory evidence indicated that Karawan brand tahini products were the likely source of this outbreak.
  • Do not eat, sell, or serve recalled tahini that is labeled as Karawan Tahini, El-Karawan Tahin,i or SoCo Tahini. Do not eat, sell, or serve products made with recalled tahini, such as hummus.
  • This outbreak was not related to another recent multistate outbreak of Salmonella Concord infections linked to tahini. Ill people in the previous outbreak were infected with a different outbreak strain of Salmonella Concord.

Information – FDA issues new draft guidance to improve the safety of seeds for sprouting

FDA alfalfa

“Over the past 22 years, the 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.”

The U.S. Food and Drug Administration 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.

New Zealand – Food poisoning associated with consumption of raw mussels

MPI Mussels

New Zealand Food Safety is urging people to ensure they cook raw mussels thoroughly after an increase in cases of food poisoning associated with commercially grown New Zealand mussels.

Over the past 6 weeks, there has been an increase in cases of people with food poisoning caused by Vibrio parahaemolyticus.

Vibrio parahaemolyticus is a marine microorganism that occurs naturally throughout the world.  Not all Vibrio parahaemolyticus strains cause illness in humans and surveys to date of New Zealand shellfish have found very low levels and incidence of disease-causing strains.

However, some strains do cause illness in humans.  Symptoms are predominantly stomach cramps and watery diarrhoea and sometimes nausea, vomiting and fever.  Generally people who are sick recover without hospital treatment, however, in severe cases hospitalisation is required.

New Zealand Food Safety’s director of food regulation Paul Dansted says the majority of people who have become sick have bought commercially-grown New Zealand mussels harvested from a single growing area in the Coromandel and were eaten raw or partially cooked. This growing area has been closed by New Zealand Food Safety while further investigations continue.

“Additional testing is being done to confirm the type of Vibrio parahaemolyticus that has caused this illness.  It is possible that the strain of Vibrio parahaemolyticus is unusually aggressive which may mean that even low numbers could cause illness.

“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.

“Until we have more information, New Zealand Food Safety is reminding people to take care when handling, preparing, and consuming mussels.”

Cooking temperatures for mussels should be above 65°C. This will ensure that any Vibrio parahaemolyticus that is present in mussels will be destroyed.

  • Don’t eat raw or undercooked mussels or other shellfish. Cook them before eating.
  • Always wash your hands with soap and water after handing raw shellfish.
  • Avoid contaminating cooked shellfish with raw shellfish and its juices.

New Zealand Food Safety’s advice to consumers who are pregnant or have low immunity is to avoid eating raw shellfish.

USA – Outbreak of E. coli Infections Linked to Ground Beef Final Update

This outbreak appears to be over. Ill people in this outbreak ate ground beef from many sources. No single supplier, distributor, or brand of ground beef was identified. Consumers and restaurants should always handle and cook ground beef safely to avoid foodborne illness.

Sweden – New outbreak of Yersinia infection is being investigated

Outbreak News

In Sweden, the National Institute of Public Health, or Folkhälsomyndigheten is reporting a new outbreak of infections caused by Yersinia enterocolitica type O3. The source of infection is still unknown.

So far, 26 cases of disease have been confirmed to belong to the outbreak by means of whole-genome sequencing. Another handful of cases are investigated. Since the current outbreak strain of Yersinia enterocolitica type O3 has been found in different parts of the country, it is likely that a food borne infection. The current outbreak strain differs from the one that caused a Yersinia outbreak earlier in the spring.During the middle of May, an number of reported cases of Yersinia infection has been seen in Sweden. Seven regions from different parts of the country have reported cases, but the majority of cases come from the northernmost regions of the country.
