Florida Listeria Outbreak Solved

Unknown

The Florida Department of Health, CDC, public health and regulatory officials in several other states, and the U.S. Food and Drug Administration (FDA) are collecting different types of data to investigate a multistate outbreak of Listeria monocytogenes infections. As a result of this investigation, Big Olaf Creamery in Sarasota, FL, is voluntarily contacting retail locations to recommend against selling their ice cream products. Consumers who have Big Olaf Creamery brand ice cream at home should throw away any remaining product.

Public health officials continue to interview people about the foods they ate in the month before they got sick. Of the 17 people interviewed, 14 (82%) reported eating ice cream. Among 13 people who remembered details about the type of ice cream they ate, six reported eating Big Olaf Creamery brand ice cream or eating ice cream at locations that might have been supplied by Big Olaf Creamery.

On July 1, 2022, Big Olaf Creamery in Sarasota, FL, voluntarily began contacting retail locations to recommend against selling their ice cream products. Consumers who have Big Olaf Creamery brand ice cream at home should throw away any remaining product.

Among 13 people who remembered details about the type of ice cream they ate, six reported eating Big Olaf Creamery brand ice cream or eating ice cream at locations that might have been supplied by Big Olaf Creamery.

As of June 29, 2022, a total of 23 people infected with the outbreak strain of Listeria monocytogenes have been reported from 10 states. Of the 22 people with information, 20 sick people reported living in or traveling to Florida in the month before they got sick, although the significance of this is still under investigation. Illnesses started on dates ranging from January 24, 2021, through June 12, 2022.

Sick people range in age from less than 1 to 92 years, with a median age of 72, and 52% are male. Twenty-two people (96%) have been hospitalized. Five people got sick during their pregnancy, and one illness resulted in a fetal loss. One death has been reported from Illinois.

Unlinked Listeria Outbreaks in Canada and Denmark sicken 12, killing 5

Two residents in a retirement home in Ottawa, Canada, have died from listeria poisoning. The deaths are part of a month-long outbreak at the resident home.

Ottawa Public Health (OPH) says officials are investigating the outbreak at City View Retirement Community in Nepean. As of the last update on Tuesday, there were four confirmed cases among residents of the home, including the two people who have died. 

High-risk foods, including deli meats, were removed from the home’s menu as of May 4, according to OPH.

OPH has conducted 10 site visits to the facility over the past month including multiple food safety compliance inspections and follow-up inspections, and at least one hazard analysis critical control point audit. None of the food tested by OPH has come back positive for listeria.

The investigation is supported by Public Health Ontario, as well as its laboratories, and the Canadian Food Inspection Agency. 

OPH has submitted food samples and environmental swab samples to the provincial lab, which needs about one week to provide preliminary results and an additional week to provide final results.

Eight people in Denmark have been infected with Listeria in the space of two weeks and three have died.

The Statens Serum Institut, Danish Veterinary and Food Administration (Fødevarestyrelsen) and DTU Food Institute are investigating to try and find the source of the outbreak.

Five men and three women became infected with the same type of Listeria between May 13 and 29, this year.

Patients range from 33 to 93 years old and all of them had an underlying disease or other immune system issue prior to infection that made them particularly vulnerable. Two had meningitis, five had sepsis, including a pregnant woman, and one had a cerebral abscess.

All eight have been hospitalized and three people died within 30 days of the sample being taken. Seven of them are from the Hovedstaden region of the country.

Dole Salad Listeria Outbreak over after three deaths

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.

Listeria and Enoki Mushrooms

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.

Bean Sprouts and Soy Sprouts recalled over Listeria

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.

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. Soy sprouts are sold in 5 lb bulk and 10 lb bulk. The lot numbers are printed on the retail packs and on bulk cardboard boxes in the barcode (the last 3 digits.)

Listeria Outbreak prompts Tyson to recall 8,500,000 pounds of cooked chicken

Tyson Foods Inc., a Dexter, Mo. establishment, is recalling approximately 8,492,832 pounds of ready-to-eat (RTE) chicken products that may be adulterated with Listeria monocytogenes, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.

The frozen, fully cooked chicken products were produced between December 26, 2020 and April 13, 2021. The products that are subject to recall are listed here. View the labels here.

The products subject to recall bear establishment number “EST. P-7089” on the product bag or inside the USDA mark of inspection. These items were shipped nationwide to retailers and institutions, including hospitals, nursing facilities, restaurants, schools and Department of Defense locations.

On June 9, 2021, FSIS was notified of two persons ill with listeriosis. Working in conjunction with the Centers for Disease Control and Prevention (CDC) and state public health partners, FSIS determined there is evidence linking the Listeria monocytogenesillnesses to precooked chicken produced at Tyson Foods Inc. The epidemiologic investigation identified three listeriosis illnesses, including one death, between April 6, 2021 and June 5, 2021. During routine sample collection, FSIS collected two precooked chicken samples from two establishments that are closely related genetically to Listeria monocytogenes from ill people. One of the samples was collected at Tyson Foods Inc. FSIS is continuing to work with federal and state public health partners to determine if there are additional illnesses linked to these products.

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.

Listeriosis can cause fever, muscle aches, headache, stiff neck, confusion, loss of balance and convulsions sometimes preceded by diarrhea or other gastrointestinal symptoms. An invasive infection spreads beyond the gastrointestinal tract. In pregnant women, the infection can cause miscarriages, stillbirths, premature delivery or life-threatening infection of the newborn. In addition, serious and sometimes fatal infections in older adults and persons with weakened immune systems. Listeriosis is treated with antibiotics. Persons in the higher-risk categories who experience flu-like symptoms within two months after eating contaminated food should seek medical care and tell the health care provider about eating the contaminated food.

FSIS is concerned that some product may be in consumer and institutional freezers. Consumers should not eat these products. Institutions should not serve these products. These products should be thrown away.

A lot of Smoked Fish recalled due to Listeria

Banner Smoked Fish, Inc. of Brooklyn, NY is voluntarily expending recalling its SMOKED FISH, SALADS, PICKLED FISH PRODUCTS, and CREAM SAUCE PRODUCTS (product names and photos of labels are listed below) of all products within expiry, in all package sizes, all package types and all lots. The recall is because the products have 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.

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 products were distributed to CA, IL, and TX through produce distributors or wholesalers to retail stores nationwide.

The Enoki comes in a 200g/7.05ounces, clear plastic and green package with the description “Enoki Mushroom” in English and labeled “Product of Korea”. On the back there is UPC 809165582015 on the bottom left and Golden Medal Mushroom Inc.’s name and address, along with instructions to keep refrigerated and cook through before eating.

No illnesses have been reported to date.

The potential for contamination was noted after routine testing by Michigan Department of Agriculture and Rural Development revealed the presence of Listeria monocytogenes in 200g package of Enoki.

The distribution of the product has been suspended.

What to know about Listeria

Listeria is a gram-positive, rod-shaped bacterium that is ubiquitous and can grow under either anaerobic (without oxygen) or aerobic (with oxygen) conditions. 

Listeriosis is one of the most important bacterial infections worldwide that arises mainly from the consumption of contaminated food. The disease is caused by Listeria monocytogenes, which is considered an opportunistic pathogen that affects mainly those with underlying immune conditions, such as pregnant women, neonates, and elders, resulting in septicemia, meningitis, and/or meningoencephalitis. 

Foods commonly identified as sources of Listeria infection include improperly pasteurized fluid milk, cheeses (particularly soft-ripened varieties, such as traditional Mexican cheeses, Camembert, and ricotta), ice cream, raw vegetables, fermented raw-meat sausages, raw and cooked poultry, and cooked, ready-to-eat (RTE) sliced meats—often referred to as “deli meats.” The danger posed by the risk of Listeria in RTE meats prompted the USDA to declare the bacterium an adulterant in these kinds of meat products and, as a result, to adopt a zero-tolerance policy for the presence of this deadly pathogen. The amount of time from infection to the onset of symptoms—typically referred to as the incubation period—can vary to a significant degree. According to the CDC, symptoms of Listeria infection can develop at any time from the same day of exposure to 70 days after eating contaminated food.

Listeria monocytogenes sickens seven in Connecticut, Maryland, New York and Virginia

As of February 11, 2021, seven people infected with the outbreak strain of Listeria monocytogenes have been reported from four states – Connecticut, Maryland, New York and Virginia. Illnesses started on dates ranging from October 20, 2020, to January 22, 2021, with six recent illnesses in 2021.

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 2 to 4 weeks to determine if a sick person is part of an outbreak.

Sick people range in age from 45 to 75 years, with a median age of 61. Six people are Hispanic, and 43% are female. All seven people have been hospitalized. No deaths have been reported.

State and local public health officials are interviewing people about the foods they ate in the month before they got sick. Of the four people interviewed, three reported eating at least one type of Hispanic-style fresh and soft cheeses and all three reported eating queso fresco. Public health officials are continuing to interview sick people to try to identify a specific type or brand of cheese.

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 closely related genetically. This means that people in this outbreak likely got sick from the same food.

State officials are testing samples of Hispanic-style fresh and soft cheeses that they collected from stores where sick people report purchasing cheeses from.
