Listeria Lawsuit Update: Injuries, Recall Status, and Legal Options

Listeria monocytogenes is a foodborne bacterium that can cause mild intestinal illness or serious invasive infection. Pregnant women, newborns, adults 65 and older, and people with weakened immune systems face the greatest risk of severe complications.

A potential legal claim generally depends on identifying the contaminated product or outbreak, confirming the diagnosis, documenting the timing of exposure and illness, and establishing damages through medical and other evidence.

Quick Facts

• CDC estimates that about 1,600 people in the United States develop Listeria infection each year.
• Invasive listeriosis can cause sepsis, meningitis, neurological complications, pregnancy loss, premature delivery, and death.
• A 2026 multistate outbreak linked to requesón and soft cheese caused 15 illnesses, 14 hospitalizations, and one death.
• Potential claims may depend on product identification, outbreak evidence, medical testing, timing, causation, and documented losses.

Latest Listeria Outbreak and Lawsuit Developments

August 2026

• August 26, 2026 – FDA announced that its investigation of the multistate, multi-year Listeria outbreak linked to requesón and other soft cheese manufactured by Clover Hill Dairy was complete. FDA reported 15 illnesses in four states, 14 hospitalizations, and one death [1]

June 2026

• June 29, 2026 – CDC reported that whole genome sequencing linked Listeria found in requesón cheese and environmental samples to the outbreak strain found in sick patients. CDC said epidemiologic, laboratory, and traceback data showed contaminated cheese was making people sick [2]
• June 18, 2026 – Clover Hill Dairy expanded its recall to include all cheese products manufactured at its facility while federal and state investigators continued evaluating the source and scope of contamination [2]

September 2025

• September 30 2025 – Freshrealm recalled chicken fettuccine alfredo meals sold through retailers including Walmart, Kroger, and Trader Joe’s after they were linked to a multistate Listeria outbreak [6]. The outbreak was associated with at least 20 illnesses in 15 states, including 19 hospitalizations and 4 deaths, with federal investigators using laboratory and traceback evidence to connect cases to the contaminated products.
• June 18, 2025 – Marketside Grilled Chicken Alfredo was pulled from Walmart stores after federal testing found Listeria monocytogenes in the ready-to-eat meal [6]. The recalled products were made by FreshRealm and included 32.8-ounce and 12.3-ounce trays with specified June 2025 best-by dates. Genetic analysis showed the Listeria strain in the product matched samples connected to the broader outbreak investigation.
  

  What Is Listeria?

  Listeria monocytogenes is a bacterium that can contaminate food and cause an illness known as listeriosis.

  CDC describes Listeria infection as uncommon but potentially serious, particularly when the bacteria spread beyond the gastrointestinal tract. An estimated 1,600 people in the United States become ill from Listeria each year [3].

  How Does Listeria Contaminate Food?

  Listeria can enter food through contaminated raw ingredients, processing environments, equipment, storage areas, or handling practices.

  Unlike many foodborne bacteria, Listeria can survive and grow at refrigerator temperatures, which can allow contamination to persist in refrigerated ready-to-eat foods.

  Products commonly implicated in outbreaks have included soft cheeses, deli meats, ready-to-eat foods, sprouts, smoked seafood, and other refrigerated products.

  What Happened in the 2026 Soft Cheese Outbreak?

  FDA and CDC investigated a multistate outbreak linked to requesón, a soft cheese similar to ricotta, manufactured by Clover Hill Dairy in Mechanicsville, Maryland.

  FDA’s final August 2026 update reported 15 people infected with the outbreak strain across four states. Fourteen were hospitalized, and one death was reported.

  Illnesses dated back to March 2023, demonstrating how whole genome sequencing and traceback work can connect cases that occur over an extended period.

  How Did Investigators Link the Cheese to the Outbreak?

  CDC used its PulseNet system and whole genome sequencing to compare bacteria isolated from sick people with bacteria found in food and environmental samples.

  Listeria was detected in multiple samples of requesón cheese and in environmental samples. Genetic testing showed that the bacteria from the cheese were closely related to the bacteria recovered from patients.

  This kind of laboratory evidence can be important in a food-poisoning lawsuit because it may help connect a contaminated product to a specific outbreak.

  What Are the Symptoms of Listeriosis?

  Symptoms depend on whether the infection remains in the intestines or becomes invasive.

  CDC says intestinal illness may cause diarrhea and vomiting, while invasive listeriosis may cause fever, muscle aches, fatigue, headache, stiff neck, confusion, loss of balance, or seizures [4]

  Invasive illness is significantly more serious because the bacteria have spread beyond the gastrointestinal tract.

  How Soon Can Listeria Symptoms Appear?

  CDC says intestinal symptoms typically begin within about 24 hours after eating contaminated food and usually last one to three days.

  Symptoms of invasive listeriosis usually begin within approximately two weeks, although timing can vary.

  The time between consumption and diagnosis can be important when comparing a patient’s food history with outbreak and recall information.

  Who Is Most at Risk?

  Listeria is especially dangerous for pregnant women, newborns, adults aged 65 or older, and people with weakened immune systems.

  People outside these groups can still become infected, but CDC says they are less likely to become seriously ill.

  Age, pregnancy status, immune suppression, underlying disease, and other medical conditions can affect the severity of infection.

  How Does Listeria Affect Pregnant Women?

  Pregnant women may experience only fever, fatigue, or muscle aches, and some may have no obvious symptoms.

  Despite mild maternal symptoms, infection during pregnancy can lead to miscarriage, stillbirth, premature delivery, or a life-threatening infection in the newborn [5]

  Pregnancy-related losses and neonatal complications may materially affect the damages and medical evidence involved in an individual claim.

  What Is Invasive Listeriosis?

  Invasive listeriosis occurs when the bacteria spread beyond the intestines into the bloodstream, central nervous system, or other parts of the body.

  Potential complications include bacteremia, sepsis, meningitis, encephalitis, neurological injury, and death.

  Hospitalization, blood cultures, spinal-fluid testing, imaging, infectious-disease records, and antibiotic treatment may help document invasive illness.

  How Is Listeria Diagnosed?

  Listeriosis is generally confirmed through laboratory testing of blood or another normally sterile body fluid.

  A laboratory-confirmed diagnosis can become important evidence when determining whether a person’s illness matches an outbreak strain.

  Patients should preserve laboratory reports, culture results, hospital records, discharge summaries, and infectious-disease consultations.

  What Foods Are Commonly Linked to Listeria?

  Higher-risk foods can include queso fresco and other soft cheeses, deli meats, hot dogs, refrigerated pâté, smoked seafood, raw sprouts, melons, and unpasteurized milk products.

  A recalled food is not automatically proven to have caused a particular person’s illness. Purchase history, product codes, consumption timing, laboratory evidence, and outbreak data may all be relevant.

  What Must Be Proven in a Listeria Lawsuit?

  A claimant generally must establish that a contaminated product or another legally responsible source caused the infection and resulting damages.

  Evidence may include purchase records, packaging, lot or date codes, outbreak notices, genetic testing, medical records, laboratory results, food history, and witness testimony.

  An outbreak investigation can strengthen causation evidence when public-health agencies identify a specific food, manufacturer, lot, or production facility.

  Who May Be Liable?

  Potentially responsible parties may include food manufacturers, processors, distributors, wholesalers, retailers, restaurants, or other businesses involved in producing or supplying contaminated food.

  Potential claims may involve negligence, product liability, breach of warranty, food-safety violations, or other theories available under applicable state law.

  A recall or outbreak does not automatically establish liability for every illness. Product identification, contamination, causation, and damages must be evaluated individually.

  Who May Be Affected?

  Potentially affected consumers include people who ate food linked to a confirmed or suspected Listeria outbreak and subsequently developed laboratory-confirmed listeriosis or another serious complication.

  Pregnant women who suffered miscarriage, stillbirth, premature delivery, or neonatal infection after a documented exposure may also warrant legal review.

  Families may have potential wrongful-death claims when Listeria infection contributes to a fatal illness, depending on applicable law and available evidence.

  Do I Qualify?

  • Did you eat a food later recalled or linked to a confirmed Listeria outbreak?
  • Were you diagnosed with listeriosis through blood culture or other laboratory testing?
  • Did the illness cause hospitalization, invasive infection, pregnancy complications, neurological injury, or another serious medical outcome?
  • Do you have purchase records, packaging, medical records, laboratory results, or outbreak information connecting your illness to the food?

  An individualized legal review can determine whether product identification, laboratory evidence, exposure timing, causation, damages, and applicable filing deadlines support a claim.

  What Evidence Should I Preserve?

  Preserve receipts, loyalty-card records, delivery records, food packaging, labels, lot codes, photographs, recall notices, and any remaining product if public-health officials have not instructed otherwise.

  Medical evidence may include blood cultures, hospitalization records, infectious-disease consultations, antibiotic treatment, pregnancy records, neonatal records, pathology, and discharge summaries.

  Keep a timeline showing when the food was purchased and eaten, when symptoms began, when medical care was obtained, and when the diagnosis was confirmed.
