Deadly listeria outbreak linked to shakes used at nursing homes, hospitals. Florida impact
The shakes were sold to hospitals and long-term care institutions, including nursing homes.
As of Feb. 24, the FDA reported 38 people had been infected in 21 states, including Florida. Twelve have died.
On Feb. 22, Magnus LLC initiated a recall of 4 oz. Lyons ReadyCare and Sysco Imperial Frozen Supplemental Shakes.
The shakes came in a variety of flavors, including vanilla, chocolate, strawberry and strawberry banana.
Best buy dates were Feb. 21, 2025, through Feb. 21, 2026.
The frozen supplemental shakes were manufactured by Prairie Farms Dairy Inc. — Prairie Farms — in Fort Wayne, Indiana, under brands Lyons ReadyCare and Sysco Imperial.
The FDA is investigating the multistate outbreak of listeria in frozen supplement shakes.
As of Feb. 24, a total of 38 people have been infected with the outbreak strain in 21 states, including Florida.
Of the 38 people for whom information is available, 37 people have been hospitalized, and 12 deaths have been reported, the FDA reported.
"The true number of sick people in this outbreak is likely higher than the number reported, and the outbreak may not be limited to the states with known illnesses," the CDC said.
"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."
According to the Centers for Disease Control, the deaths associated with the outbreak occurred in:
California
Illinois
Indiana
Michigan
Minnesota
North Carolina
New York
Tennessee
Texas
Washington
The shakes were sold nationwide to institutional settings, such as long-term care facilities, including hospitals, the FDA said.
Of the 38 people for whom information is available, 34 — 89% — reported living in long-term care facilities or were hospitalized prior to becoming sick.
Records reviewed from facilities indicated nutritional shakes were available to residents, the FDA said.
Those infected during the outbreak ranged in age from 43 to 101, with a median age of 78, according to the CDC.
There are 21 states with known listeria outbreaks related to the recall, as of Feb. 24, according to the FDA. States with cases include:
Alabama
California
Colorado
Connecticut
Florida
Illinois
Indiana
Maryland
Michigan
Minnesota
Missouri
North Carolina
Nevada
New York
Ohio
Oklahoma
Pennsylvania
Tennessee
Texas
Washington
West Virginia
The Centers for Disease Control had previously begun tracking the same outbreak in 2018, with 20 cases cropping up throughout 2024 and 2025.
"Sick people were residents in long-term care facilities and nursing homes and the likely source was a food served in those types of institutions, but there was not enough information to identify a specific food," the CDC said.
"In February 2025, after traceback identified a product of interest, the outbreak strain was found in environmental samples from Prairie Farms."
"Distributors and foodservice customers, including hospitals and long-term care facilities who purchased or received recalled Lyons ReadyCare and Sysco Imperial Frozen Supplemental Shakes should not sell or serve these products," the FDA said.
"Carefully clean and sanitize any surfaces or containers that they touched and follow FDA's safe handling and cleaning advice to reduce the risk of cross-contamination. Listeria can survive in refrigerated temperatures and can easily spread to other foods and surfaces."
Listeria are bacteria that can contaminate many foods, the CDC said. People who eat contaminated food can get infected with the bacteria.
"The disease-causing bacteria can be found in many places, including soil, water, sewage, rotting vegetation, and animals," the FDA said.
Signs and symptoms of listeriosis depend on the person infected, and the body part affected, according to the Centers for Disease Control.
"Listeriaare most likely to harm pregnant women, newborns, older adults, and people with weakened immune systems."
According to the Mayo Clinic, if you develop a listeria infection, symptoms could include:
Fever
Chills
Muscle aches
Nausea
Diarrhea
"Symptoms might begin a few days after you've eaten contaminated food, but it can take 30 days or more before the first signs and symptoms of infection begin," the Mayo Clinic said.
If the listeria infection spreads to your nervous system, signs and symptoms can include:
Headache
Stiff neck
Confusion or changes in alertness
Loss of balance
Convulsions
Especially for those in high-risk groups, the CDC offers the following suggestions to avoid the listeria bacteria found in food. Do not eat:
Unpasteurized soft cheeses, such as queso fresco and brie.
Unheated cheeses sliced at a deli.
Unheated deli meat, cold cuts, hot dogs, and fermented or dry sausages.
Premade deli salads, such as coleslaw and potato, tuna, or chicken salad.
Refrigerated pâté or meat spreads.
Refrigerated smoked fish.
Raw or lightly cooked sprouts.
Cut melon left out for more than 2 hours. One hour if it's exposed to temperatures hotter than 90 degrees.
Cut melon in refrigerator for more than a week.
Raw (unpasteurized) milk, yogurt, and ice cream.

What to know about deadly brain-eating amoeba
COLUMBIA, S.C. -- A 12-year-old boy died from a brain-eating amoeba two weeks after a holiday weekend on a popular South Carolina lake. The brain-eating amoeba enters the body when water is forced up the nose, like when someone jumps or dives in the water. It causes an infection that swells the brain and destroys tissue. Fewer than 10 cases are reported each year in the U.S., but almost all are fatal. Here are some things to know about the amoeba, its latest victim and other dangers on freshwater lakes: The amoeba's scientific name is Naegleria fowleri and it is most dangerous in very warm water, including in lakes and rivers in the southern part of the U.S. and other places with hot, sometimes dry summers like Pakistan and Australia. The amoeba enters the brain through the olfactory nerve in the nose. Once inside, it causes an infection called primary amebic meningoencephalitis. Symptoms start as a fairly standard headache and nausea. By the time the pain becomes severe, it is almost always too late to save the infected person. Of the 167 cases reported in the U.S. between 1962 and 2024, only four people have survived, according to the U.S. Centers for Disease Control and Prevention. Most of the deaths happened within five days of getting sick, according to the CDC. Jaysen Carr went swimming at Lake Murray about 15 miles (24 kilometers) west of Columbia over the July Fourth weekend. He got sick several days later and died on July 18. His father and mother had never heard of the amoeba before a doctor in tears told them what tests of his spinal fluid had found. Clarence Carr said he was shocked to learn South Carolina, like most other U.S. states, has no law requiring public reporting of deaths or infections from the amoeba. The lake wasn't closed and no water testing was performed. 'My son was a very smart individual. If he had one warning, he would have thought swimming in the lake was a bad idea,' Carr said. The amoeba is fairly common and is most dangerous when the water is warm. Researchers are trying to figure out why the infections are so rare. Some people have been found to have had antibodies, signalling they may have survived exposure. Others may die from brain swelling and other problems without the amoeba ever being detected. 'My son lost his life swimming. We assumed it was safe,' Carr said. The amoeba can show up in hot springs, rivers and, on rare occasions, in tap water. That's why doctors recommend using sterile water for cleaning nasal passages with a neti pot. The only way to be completely safe is to not swim in lakes or rivers and, if you do, keep your head above water. Pinching your nose or using nose clips when diving or swimming can keep water out of your nose. There are other dangers in swimming in lakes and rivers instead of pools, where chemicals can kill off dangerous bacteria and other organisms. A mouthful of water could contain bacteria. And while the bacteria normally live in the intestines of healthy people and animals, some strains can cause a range of conditions, including urinary tract infection, cystitis, intestinal infection and vomiting, with the worst cases leading to life-threatening blood poisoning, according to the Mayo Clinic. Algae can also cause illnesses. Cyanobacteria — also referred to as blue-green algae — are plant-like organisms that live in water. The algae can look like foam, scum, mats, or paint on the surface of the water and can grow underneath it. The organisms can quickly grow out of control, or 'bloom," in warm weather, helped along by excessive nutrients in fertilizers and pet waste carried along by stormwater. Some of the algae produce toxins that can cause symptoms including skin irritation, stomach cramps, vomiting, nausea, diarrhea, fever, sore throat, headache, muscle and joint pain, mouth blisters, seizures, and acute liver damage, according to the U.S. Centers for Disease Control and Prevention.

Health officials warn of dangerous substance available in stores across the nation
Health officials are taking action against a substance that some are calling "gas station heroin." The FDA is recommending that 7-hydroxymitragynine (also known as 7-OH) — a byproduct of the plant kratom — be classified as a Schedule I drug. HHS Secretary RFK Jr. and FDA Commissioner Dr. Marty Makary emphasized the importance of getting ahead of yet another wave of addiction before it can sweep across the country. Makary compared the distribution of 7-OH to the early days of opioid prescriptions, before doctors understood the addictive nature of painkillers. "Vape stores are popping up in every neighborhood in America, and many are selling addictive products like concentrated 7-OH. After the last wave of the opioid epidemic, we cannot get caught flat-footed again," Makary said in an FDA statement. "7-OH is an opioid that can be more potent than morphine. We need regulation and public education to prevent another wave of the opioid epidemic." During a news conference on Tuesday, Makary suggested that the public health community is often late to act against dangerous substances due to a "disconnect between the ivory towers and the streets." He then pondered aloud if experts had been to vape stores, as it "affects what we see in the operating room." According to the FDA, 7-OH is beginning to be recognized for its potential to be abused because of its ability to bind to opioid receptors. Additionally, the substance is widely available and may be appealing to children and teens as it is sold in fruit-flavored gummies and even ice cream cones. The FDA is also warning that 7-OH products "may not be clearly or accurately labeled as to their 7-OH content and are sometimes disguised or marketed as kratom." "I am in favor of this move because of the relationship of the 7-OH to the opioid receptors. This is essentially an opioid. It is semisynthetic and derived from the kratom plant whose leaves make a stimulant. There are no approved 7-OH drugs or diet supplements," FOX News Senior Medical Analyst Dr. Marc Siegel told Fox News Digital. "Bravo to the FDA for this move — it should be listed as a controlled substance." Kennedy spoke about his own battle with heroin addiction. The HHS secretary described his "iron willpower" and how he gave up candy and desserts for years, making him feel as though he could do anything, until he got his hands on heroin. "I felt that I could do anything with my willpower, but this compulsion was absolutely impervious to my will, and part of the problem was just the availability. It was too easy to get this drug for me," Kennedy said. He also noted that President Donald Trump's family has also grappled with addiction. Though the president has been sober his entire life, his brother, Fred Trump Jr., struggled with alcoholism for much of his life and died at the age of 43. "I had a brother, Fred, great guy," Trump said about his brother in 2017. "But he had a problem. He had a problem with alcohol. And he would tell me, 'Don't drink. Don't drink.'" Trump said at the time that he listened to his brother because he "respected him," adding that "to this day, I've never had a drink." Sen. Markwayne Mullin, R-Okla., who attended the news conference, supported the recommendation based on his family's experience with addiction, though he did not detail exactly to whom he was referring. "It's an addiction that is ruining lives," Mullin said at a Tuesday news conference. He went on to thank Kennedy on behalf of his own family and "every single family that has dealt with this" for acting against the powerful drug. The CDC reported in May that drug overdose deaths in the country dropped in 2024. The U.S. saw "80,391 drug overdose deaths in the United States during 2024 — a decrease of 26.9% from the 110,037 deaths estimated in 2023." Additionally, the CDC found that "overdose deaths involving opioids decreased from an estimated 83,140 in 2023 to 54,743 in 2024." Kratom, the plant from which 7-OH is derived, is a tropical tree native to Southeast Asia. The FDA notes that kratom is often used to self-treat a variety of conditions, such as pain, anxiety and depression. The agency notes that it has not approved any prescription or over-the-counter drug products containing kratom or its two main chemical components: mitragynine and 7-OH.
