USA – Ten Minnesota illnesses linked to national E. coli outbreak associated with romaine lettuce

MN Health State Eurofins Food Testing UK

Health officials say do not eat romaine unless certain it is not from Yuma region

The Minnesota Department of Health (MDH) is working with the Minnesota Department of Agriculture (MDA), the Centers for Diseases Control and Prevention (CDC), the U.S. Food and Drug Administration (FDA), and public health agencies in other states to investigate an outbreak of E. coli O157 infections associated with eating romaine lettuce.

Information on the national outbreak can be found on CDC’s and FDA’s websites: CDC: E. coli and FDA Investigating Multistate Outbreak of E. coli O157:H7 Infections Likely Linked to Romaine Lettuce from Yuma Growing Region.

Ten cases of E. coli O157 infection in Minnesota residents have recently been identified and linked to the multi-state outbreak. Illness onset dates range from April 20 through May 2. The cases are from both metro and greater Minnesota counties; 90 percent are female. Three cases were hospitalized, and two developed hemolytic uremic syndrome (HUS), a potentially fatal complication that can include kidney failure and other severe problems.

All of the Minnesota cases interviewed by public health investigators reported exposure to romaine lettuce. Reported exposure locations include restaurants, grocery stores, and residential facilities. MDH is working with MDA to further investigate these exposures.

“Do not eat, buy, or sell romaine lettuce unless you can confirm it is not from the Yuma growing region,” said Kirk Smith, manager of the Foodborne, Waterborne, Vectorborne, and Zoonotic Diseases section. “The Yuma growing region includes part of western Arizona and extends into the Imperial Valley of southeastern California, but does not include Salinas Valley or other growing regions in California.” Product from the Yuma growing region should no longer be on sale; however, individuals should check their refrigerators for romaine lettuce that may have been grown in the Yuma region.

Symptoms of illness caused by E. coli O157 typically include stomach cramps and diarrhea, often with bloody stools, but only a low-grade or no fever. People typically become ill two to five days after exposure, but this period can range from one to eight days. Most people recover in five to 10 days. However, E. coli O157 infections sometimes lead to HUS. Those most at risk of developing complications from E. coli O157 include children younger than 10, the elderly, and those with weakened immune systems.

Diarrhea associated with E. coli O157 infections should not be treated with antibiotics, as this practice might promote the development of HUS. Anyone who believes they may have developed an E. coli O157 infection should contact their health care provider.

Approximately 135 cases of E. coli O157 are reported each year in Minnesota. More information on E. coli O157 and how to prevent it can be found on the MDH E. coli website.

 

USA – Ten People Sickened in Minnesota E. coli O157:H7 HUS Outbreak Linked to Romaine Lettuce: Lawsuits Possible

Food Poisoning Bulletin

Ten people are sick in a Minnesota E. coli O157:H7 HUS outbreak that is linked to romaine lettuce, according to a press release issued by the Minnesota Department of Health (MDH). Those patients are not counted in the 121 case count total sickened nationwide in the update that the CDC issued last week.

Information – Will Washing Romaine Lettuce Remove E. coli O157:H7?

Food Poisoning Bulletin 

Consumers are asking questions about this outbreak; namely, how can they protect themselves and their families? One of the questions is: will washing romaine lettuce and other produce eliminate the pathogenic bacteria?

The answer is, unfortunately, no. There are several reasons for this.

First, it only takes 10 Shiga toxin-producing E. coli bacteria to make a person very sick. That tiny amount is invisible to the eye. Washing romaine lettuce will not remove all the bacteria from microscopic surface of every leaf. Experts say that washing romaine lettuce and other produce can only reduce the number of bacteria that may be present, not completely eliminate them.

Second, pathogenic bacteria such as E. coli O157:H7 can form biofilms. These bacteria tend to cluster in small clumps so they can communicate with each other and protect each other. The bacteria produce a matrix made up of proteins, polysaccharides, and nucleic acids. The matrix is very dense and protects the bacteria from cleaning agents. It also protects the bacteria from antibiotics, and even desiccation. A simple rinse with water or a cleaning solution may not penetrate that biofilm.

And finally, the deeply crenelated surface of leafy greens provides lots of places for bacteria to hide. The same is true for other types of produce, especially cantaloupe. And, if there are tiny tears, bruises, or rips in the lettuce leaf, the bacteria can actually get inside. No amount of washing any kind of produce can reach the bacteria then.

The only thing that will kill E. coli bacteria is heat; the food must be heated to 160°F. There are very few recipes that call for cooked romaine lettuce. Grilling romaine lettuce halves will not increase the temperature enough to kill any bacteria that may be present.

South Africa – Listeria Outbreak Update Report

NICD

  1. HIGHLIGHTS

 Phase 1 of the listeriosis emergency response plan (ERP) to strengthen the response to the listeriosis outbreak has been completed. This includes development of the ERP, obtaining approval for the ERP, communication of the plan with provincial and district stakeholders, development of a risk-assessment tool to identify high-risk food production facilities for inspection, development of training material and checklists to support inspections of facilities, capacitation of NHLS food testing laboratories. These activities build on the response activities conducted before 9 April 2018, which include identification of the source, product recall and risk communication.

 A meeting to orient the provincial communications, environmental health and communicable disease authorities to the ERP was held on 24-25 April at NICD in Johannesburg. Agreement was reached on the role of the provinces and the next steps to implement the ERP.

 The number of cases of laboratory-confirmed listeriosis reported per week has decreased since the implicated products were recalled on 04 March 2018, with five additional cases reported this week (epidemiological week 15).

 As of 24 April 2018, a total of 1 024 laboratory-confirmed listeriosis cases have been reported to NICD since 01 January 2017. Since the recall 7 weeks ago, a total of 55 cases have been reported, whereas for the 7 weeks prior to the recall, 169 cases were reported. All cases that have been identified after the recall are being fully investigated.

  1. BACKGROUND

Prior to 2017, an average of 60 to 80 laboratory-confirmed listeriosis cases per year (approximately 1 per week), were reported in South Africa. In July 2017, an increase in laboratory-confirmed cases of listeriosis was reported to National Institute for Communicable Diseases (NICD) which was followed by investigations into the reported increase. On 05 December 2017, the listeriosis outbreak was declared by the Minister of Health, Dr. Aaron Motsoaledi. The source of the outbreak was identified as ready-to-eat processed meat products

manufactured at Enterprise Foods’ Polokwane production facility. A recall of affected products was initiated on 04 March 2018.

USA – Norovirus cases linked to raw British Columbia oysters: California health officials

Outbreak News Today Norwalk_Caspid

California health officials say raw oysters from British Columbia are linked to a recent outbreak of norovirus illnesses in the state, prompting warning for consumers to avoid eating raw oysters harvested from south and central Baynes Sound, in British Columbia, Canada.

In California, as of April 27, approximately 100 individuals have reported illness after they consumed raw British Columbian oysters sold by restaurants and retailers throughout the state. Laboratory testing has confirmed norovirus infection in several patients from both California and Canada. Although the number of reported new illnesses has decreased during the last week, the investigation is ongoing.

Canada has reported 172 cases of gastrointestinal illness linked to consumption of raw oysters.

USA – Multistate Outbreak of E. coli O157:H7 Infections Linked to Romaine Lettuce

CDC

What’s New?

  • Twenty-three more ill people from 10 states were added to this investigation since the last update on April 27, 2018. One death was reported from California.
  • Three more states have reported ill people: Kentucky, Massachusetts, and Utah.
  • The most recent illness started on April 21, 2018. Illnesses that occurred in the last two to three weeks might not yet be reported because of the time between when a person becomes ill with E. coli and when the illness is reported to CDC.

Canada – CFIA – FDA – Norovirus Outbreak

FDA 

The U.S. Food and Drug Administration, along with the Centers for Disease Control and Prevention (CDC), the Public Health Agency of Canada, the Canadian Food Inspection Agency, and state and local partners, are investigating a multi-state outbreak of Norovirus illnesses that are linked to oysters.

What is the Problem and What is being Done About It?

The U.S. Food and Drug Administration is working with federal, state, and local officials regarding a norovirus outbreak linked to raw oysters from British Columbia, Canada. The FDA has confirmed that potentially contaminated raw oysters harvested in the south and central parts of Baynes Sound, British Columbia, Canada, were distributed to CA, IL, MA, and WA. It is possible that additional states received these oysters either directly from Canada or through further distribution within the U.S.

FDA and the states are conducting a traceforward investigation to determine where the raw oysters were distributed and ensure they’re removed from the food supply. Retailers should not serve raw oysters harvested from the following harvest locations (or landfiles) within Baynes Sound: #1402060, #1411206, #1400483, and #278757.

Oysters can cause food-related illness if eaten raw, particularly in people with compromised immune systems. Food contaminated with noroviruses may look, smell, and taste normal.

Canada- Canada Norovirus outbreak grows: 172 cases from three provinces

Outbreak News Today 

 

In a follow-up on the norovirus and gastrointestinal illness outbreak linked to raw oysters from British Columbia, Canadian health officials report 46 additional cases.

Currently, a total of 172 cases of gastrointestinal illness linked to oyster consumption have been reported in three provinces: British Columbia (132), Alberta (15), and Ontario (25). No deaths have been reported.

Based on work conducted by the British Columbia CDC, local and federal agencies and the shellfish industry, four shellfish farms linked to illnesses have been closed. The investigation has identified that most people were infected after consuming oysters harvested in south and central Baynes Sound, BC.

The investigation into sources of contamination impacting the shellfish farms in south and central Baynes Sound is ongoing.

Oysters are a known risk for causing food-related illness if consumed as a raw product. Norovirus illnesses can be avoided if raw oysters are cooked to an internal temperature of 90° Celsius/194° Fahrenheit for a minimum of 90 seconds, and proper hand washing and food safety practices are followed.
