A total of 18 people infected with the outbreak strain of Listeria monocytogenes were reported from 13 states – Idaho 1, Iowa 2, Maryland 1, Michigan 1, Minnesota 2, Nevada 1, North Carolina 1, Ohio 3, Oregon 1, Pennsylvania 1, Texas 2, Utah 1, and Wisconsin 1. The true number of sick people in an outbreak is likely higher than the number reported, and the outbreak may not have been limited to the states with known illnesses. This is because some people recover without medical care and are not tested for Listeria.

Sick people ranged in age from 50 to 94 years, with a median age of 76, and 83% were female. Of 16 people with information available, all were hospitalized. Three deaths were reported, one each from Michigan, Ohio, and Wisconsin.

Whole genome sequencing (WGS) showed that bacteria from sick people’s samples were closely related genetically. This suggests that people in this outbreak got sick from the same food.

In October 2021, before the most recent CDC investigation began, the Georgia Department of Agriculture identified Listeria in a Dole brand garden salad as part of a routine sampling program of food at grocery stores. WGS later showed that the Listeria in the garden salad was the outbreak strain. The garden salad was produced at Dole’s Bessemer City, North Carolina, facility.

After CDC reopened this outbreak investigation, the Michigan Department of Agriculture and Rural Development collected samples of packaged salads from retail stores for testing and identified the outbreak strain of Listeria in a Marketside brand package of shredded iceberg lettuce. The shredded iceberg lettuce was produced at Dole’s Yuma, Arizona, facility.

Dole conducted a root cause analysis and collected samples from their facilities and equipment for testing. Dole found Listeria on equipment used to harvest iceberg lettuce. FDA conducted WGS and found that the Listeria on the equipment was the outbreak strain.

Dole’s continued investigation found the outbreak strain on a piece of equipment in their Yuma facility and in packaged salads on hold that were included in the initial recall.

On December 22, 2021, Dole recalled all Dole-branded and private label packaged salads processed at their Bessemer City, North Carolina, and Yuma, Arizona, facilities.

On January 7, 2022, Dole recalled additional products containing iceberg lettuce harvested by the contaminated harvesting equipment.

WiseTrade Corporation of Irvine, California is recalling all its cases of its 200g/7.05oz packages of ENOKI MUSHROOM (Product of Korea) because it has the potential to be contaminated with Listeria monocytogenes, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.

The recalled Enoki Mushroom product was distributed in CA to produce distributors or wholesalers for further distribution to retail stores.

The Enoki Mushroom comes in a 200g/7.05oz clear plastic package with the following description “Global Fresh Marketing Enoki Mushrooms” in the front and back Wisetrade Coporation Irvine, CA 92618.

The UPC is 809728-95012 on the back side of the package.

There is no lot code or dates on a package.

No illnesses have been reported to date in connection with this problem. The distribution of the product has been suspended.

The potential for contamination was discovered after a retail sample collected and analyzed by California Department of Public Health (CDPH) and revealed the presence of Listeria monocytogenes in 7.05 oz. package of Enoki mushroom.

As of February 1, 2022, 17 people infected with the outbreak strain of Listeria monocytogenes have been reported from 13 states.

Illnesses started on dates ranging from August 16, 2014, to December 30, 2021.

Sick people range in age from 50 to 94 years, with a median age of 75, and 82% are female. Of 15 people with information available, 13 have been hospitalized. Two deaths have been reported from Michigan and Wisconsin.

Dole collected samples from their facilities and equipment for testing and found Listeria on equipment used to harvest iceberg lettuce. FDA conducted whole genome sequencing and found that the Listeria on the equipment was the outbreak strain.

USDA’s Food Safety and Inspection Service (FSIS) late Friday issued  a public health alert due to concerns that ready-to-eat (R-T-E) chicken salad products produced by Simply Fresh Market, a Marietta, Ga. establishment, may be contaminated with Listeria monocytogenes.The FSIS pubic health alert said a recall was not requested because the known affected product is no longer available in commerce for consumers to purchase. FSIS’s  concern is that some product may be in consumers’ refrigerators. Consumers who have purchased these products are urged not to consume them. These products should be thrown away or returned to the place of purchase.The R-T-E chicken salad with apples and walnuts items were produced on Jan. 17, 2022. The following product is subject to the public health alert [view label]:

  • 8-oz and 16-oz. deli hinged containers of “simply fresh MARKET CHICKEN SALAD Apples & Walnuts” with a sell by date of “1/25” printed on the label.

The products bear establishment number “EST. P47170” inside the USDA mark of inspection. These items were shipped to three local markets in Atlanta,

The contamination  was discovered when the company notified FSIS that product sampling reported positive Listeria monocytogenes results.

There have been no confirmed reports of adverse reactions due to consumption of these products. Anyone concerned about an illness should contact a health care provider.

Consumption of food contaminated with L. monocytogenes can cause listeriosis, a serious infection that primarily affects older adults, persons with weakened immune systems, and pregnant women and their newborns. Less commonly, persons outside these risk groups are affected.

Fresh Express Lettuce – 10 sick with 1 death in 8 states – 2021

Illnesses: As of December 21, 2021, 10 people infected with the outbreak strain of Listeria monocytogenes have been reported from eight states: Illinois, Massachusetts, Michigan, New Jersey, New York, Ohio, Pennsylvania and Virginia. Illnesses started on dates ranging from July 26, 2016 through October 19, 2021. Sick people range in age from 44 to 95 years, with a median age of 80, and 60% are female. All 10 people have been hospitalized. One death has been reported from Pennsylvania. WGS showed that bacteria from sick people’s samples are closely related genetically. This means that people in this outbreak likely got sick from the same food.

Traceback and Recall: On December 16, 2021, the Michigan Department of Agriculture identified the outbreak strain of Listeria in a bag of Fresh Express Sweet Hearts packaged salad. On December 20, 2021, Fresh Express recalled several brands of packaged salad products. The recall includes all Use-By Dates with product codes Z324 through Z350.

Dole Lettuce – 16 sick with 2 deaths in 13 states – 2021

Illnesses: As of December 17, 2021, 16 people infected with the outbreak strain of Listeria monocytogenes have been reported from 13 states: Idaho, Iowa, Maryland, Michigan, Minnesota, Nevada, North Carolina, Ohio, Oregon, Pennsylvania, Texas, Utah and Wisconsin. Illnesses started on dates ranging from August 16, 2014, to October 17, 2021. Sick people range in age from 50 to 94 years, with a median age of 76, and 81% are female. Of 14 people with information available, 12 have been hospitalized. Two deaths have been reported from Michigan and Wisconsin. WGS showed that bacteria from sick people’s samples are closely related genetically. This suggests that people in this outbreak got sick from the same food.

Traceback and Recall: In October 2021, the Georgia Department of Agriculture identified the outbreak strain of Listeria in a Dole brand garden salad as part of a routine sampling program of food at grocery stores. As a result, Dole recalled some of their garden salad products that are now past their “best if used by” dates. This sampling was not part of this outbreak investigation, but WGS later showed that the Listeria bacteria in the garden salad were closely related to the outbreak strain. After CDC reopened this outbreak investigation, Michigan Department of Agriculture and Rural Development collected samples of packaged salads from retail stores for testing and identified the outbreak strain of Listeria in a Marketside brand package of shredded iceberg that was produced by Dole. On December 22, 2021, Dole recalled all Dole-branded and private label packaged salads processed at the two facilities that produced the contaminated packaged salads.

Listeria monocytogenes (Listeria) is a foodborne disease-causing bacterium; the disease is called listeriosis. Listeria can invade the body through a normal and intact gastrointestinal tract. Once in the body, Listeria can travel through the blood stream but Listeria bacteria are often found inside cells. Listeria also produces toxins that damage cells.

NOTE: earliest illness from JULY 26, 2016.

  • The U.S. Food and Drug Administration, along with the U.S. Centers for Disease Control and Prevention and our state and local partners, is working to investigate a multistate outbreak of Listeria monocytogenes infections associated with the consumption of packaged salad.
  • To date, this outbreak has been associated with 10 illnesses, 10 hospitalizations and one death spanning the following states: IL, MA, MI, NJ, NY, OH, PA and VA. Illnesses started on dates ranging from July 26, 2016, to Oct. 19, 2021.
  • Consumers who have symptoms of listeriosis infection should contact their health care provider. Most people with listeriosis include a fever, muscle aches, nausea, vomiting and diarrhea. If the more severe form of listeriosis develops, symptoms may include headache, stiff neck, confusion, loss of balance and convulsions. For the very young, the elderly and the immune-compromised, listeriosis can result in death.
  • Fresh Express voluntarily ceased production at their Streamwood, Illinois, facility and initiated a recall of certain varieties of its branded and private label salad products produced at the company’s Streamwood, Illinois, facility. The recall includes all Use-By Dates of fresh salad items with product codes Z324 through Z350.
  • Consumers, restaurants and retailers, should not eat, sell or serve recalled packaged salads. A full list of recalled products is available on the FDA’s website.
  • The FDA recommends that anyone who received recalled products use extra vigilance in cleaning and sanitizing any surfaces and containers that may have come in contact with these products to reduce the risk of cross-contamination. Listeria can survive in refrigerated temperatures and can easily spread to other foods and surfaces.
  • This is an ongoing investigation, and additional information will be provided as it becomes available.

Oregon Lox Company of Eugene, Oregon is issuing a voluntary recall of various brands of Wild Cold Smoked Keta Salmon Lox, specific lot number 22821, because it has the potential to be contaminated with Listeria rnonocytogenes, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea , abdominal pain and diarrhea, listeria infection can cause miscarriages and stillbirths among pregnant women.

The affected Wild Cold Smoked Keta Salmon product was distributed in Alaska, California, Oregon, and Washington through dis tributors. Product was shipped frozen on common carriers.

The affected Wild Cold Smoked Keta Salmon is packaged in plastic vacuum sealed packages and sold in various brands, sizes, and weights (see attached labels) . The recalled products brands and lot number are indicated in the table below:

The recall was the result of a routine sampling by the Washington State Department of Agriculture.

The purpose of this announcement is to advise you that Fullei Fresh is voluntarily recalling Bean Sprouts and Soy Sprouts as a precaution due to possible exposure to listeria monocytogenes. Affected lots are numbered consecutively between 251 and 271. They were harvested and shipped to distributors between September 14 and October 5, 2021. Both conventional and organic bean sprouts as well as soy sprouts are voluntarily recalled. No other products are affected at this time as they are grown and packed in segregated departments.

Listeria monocytogenes is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, a Listeria monocytogenes infection can cause miscarriages and stillbirths among pregnant women.

There have been no known illnesses reported in connection with these products.

Fullei Fresh conventional bean sprouts are sold in 5 lb bulk, 10 lb bulk and 8 oz retail packs. Organic bean sprouts are sold in 5 lb bulk and 4 oz retail packs.

Whole Foods Market is voluntarily recalling Cahill Cheddar Porter and Whiskey Cheddar Cheeses from 44 stores across 22 states because of a potential contamination of Listeria monocytogenes. Customers who have purchased should not consume and should dispose of the product. No illnesses have been reported to date.

Listeria monocytogenes is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, pregnant women, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages, stillbirths, and fetal infection among pregnant women.

The affected products were packaged in clear wrapping and sold in the specialty department with a Whole Foods Market scale label with “packed on” dates from May 17 – July 26, 2021. Affected products can be identified by the following information and were distributed in the states listed below:

Product Name PLU Date Range Sold States
Cheddar with Porter 93579 May 17 – July 26, 2021 Alabama, Arkansas, California, Colorado, Florida, Hawaii, Illinois, Indiana, Iowa, Louisiana, Michigan, Mississippi, Missouri, Nebraska, Nevada, New Hampshire, New York, North Carolina, Oklahoma, Texas, Wisconsin, Wyoming
Whiskey Cheddar 54784
94884

The issue was discovered when Whole Foods Market was notified by a distributor of a positive test result for Listeria monocytogenes.

As of July 2, 2021, three people infected with the outbreak strain of Listeria monocytogenes have been reported from Delaware and Texas. Illnesses started on dates ranging from April 6, 2021, to June 5, 2021.

Sick people range in age from 60 to 95 years, with a median age of 89, and 66% are male. All three people were hospitalized, and one death has been reported from Texas.

The true number of sick people in an outbreak is likely higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because some people recover without medical care and are not tested for Listeria. In addition, recent illnesses may not yet be reported as it usually takes 3 to 4 weeks to determine if a sick person is part of an outbreak.

State and local public health officials interviewed people about the foods they ate in the month before they got sick. All three people were in a long-term care facility or hospital when they got sick. These facilities served many food items, including meals with precooked chicken.

Public health investigators are using the PulseNet system to identify illnesses that may be part of this outbreak. CDC PulseNet manages a national database of DNA fingerprints of bacteria that cause foodborne illnesses. DNA fingerprinting is performed on bacteria using a method called whole genome sequencing (WGS).

WGS showed that bacteria from sick people’s samples are identical. This suggests that people in this outbreak got sick from the same food.

USDA-FSIS found the outbreak strain of Listeria in two samples of precooked chicken products during routine product testing. Along with the epidemiologic data, this suggests that people likely got sick from eating precooked chicken.

USDA-FSIS and state partners are collecting food purchase records from the long-term care facility and hospital to identify a common precooked chicken product that may be making people sick.

Until we learn more, CDC is advising people at higher risk for severe Listeria illness and facilities caring for them to take extra precautions: reheat precooked chicken to an internal temperature of 165°F, and do not eat cold dishes made with precooked chicken unless the chicken was reheated before being used in the dish.
