The FDA has closed its investigation into a fatal Listeria monocytogenes outbreak traced to Requeson and Soft Ricotta Cheese from Clover Hill Dairy. The final count is sobering: 15 illnesses across four states, 14 hospitalizations, and one death. For people with gout, the story carries a double message. Soft cheese is not a purine problem. Most cheeses measure at zero purines, which makes them some of the safest dairy foods for gout. But a food can be purine-safe and still carry a food-safety risk, and the Listeria case is a reminder that how soft cheese is stored, and who eats it, matters. This article separates those two very different questions.
What the Clover Hill requeson investigation found
Requeson is a fresh, soft white cheese popular in Mexican cooking, often spread on tortillas or stirred into dishes; soft ricotta is its closest cousin. The outbreak linked to Clover Hill Dairy sickened 15 people in four states. Fourteen were hospitalized, and one person died. The FDA first reported the outbreak on June 3, and illness onset dates ran from March 6, 2023 to July 8, 2026 — a spread of more than three years, which shows how slowly and quietly foodborne outbreaks can move. Among the 13 ill people interviewed, 5 reported eating Clover Hill requeson before they became sick. The FDA has now closed the investigation.
One detail explains why food-safety agencies describe Listeria cases as especially hard to investigate. Symptoms can take up to 70 days to appear after a person eats the contaminated food. Most foodborne illnesses surface within hours or a few days, so patients can usually point to a recent meal. With Listeria, a person who fell ill in March may have eaten the cheese in January. That gap makes interviews less reliable and makes the trail harder to follow. The up-to-70-day incubation window is a structural reason Listeria outbreaks take time to solve.
Soft cheese: near-zero purines, not a gout trigger
For gout, the cheese itself is about as safe as dairy gets. Measured purine values for cheese are 0.0 mg/100 g for cheddar, mozzarella, Swiss, and grated parmesan, all rated Safe. Fresh soft cheeses such as requeson do not have their own entry, but they fall into the same soft-cheese band — effectively no purine load. That means a bowl of requeson does not push serum urate the way a steak, a serving of anchovies, or a beer does.
Low-fat dairy is associated with lower urate in several observational studies, and including dairy in a gout diet may help you get protein, calcium, and satiety without adding purines. That makes cheeses and other dairy foods a practical tool on a low-purine plate. Our cheese purine ranking shows how the common cheeses line up, and our dairy and gout guide covers yogurt, milk, and cheese together. The point here is that the Listeria outbreak is not a reason to fear cheese for gout. It is a reason to separate purine safety from microbial safety. The first is about the chemistry of the food. The second is about how the food was made, shipped, and stored.
Who actually faces the Listeria risk
Listeria is not dangerous for everyone the same way. Healthy adults usually experience mild symptoms such as fever and muscle aches, sometimes with nausea or diarrhea. The serious forms — bloodstream infections, meningitis, and fatal outcomes — fall overwhelmingly on three groups: pregnant women, adults aged 65 and older, and people with weakened immune systems. The outbreak's toll fits that pattern: 14 hospitalizations and one death out of 15 cases is a severe disease curve, not a mild one.
Gout patients skew middle-aged and older, which means many people managing gout sit in the higher-risk group by age alone. If you have gout and are over 65, or have a condition that suppresses immunity, soft cheeses deserve more care than they would for a younger healthy adult. We do not give medical advice for pregnancy or immune-compromised situations in this article; that is a conversation for your doctor. The practical takeaway for anyone with gout is that the cheese is fine for urate, but the handling rules below protect the same people who are most likely to be reading a gout article. Our gout guide for women touches on the added caution pregnancy brings to food choices.
Safe handling rules for soft cheese
Soft cheeses are fresh products. Unlike aged cheddar or parmesan, requeson and soft ricotta are not preserved by aging, so they depend entirely on refrigeration from the dairy to your table. Four habits cover most of the risk:
- Keep the refrigerator at 40°F (4°C) or below, and check it with an appliance thermometer rather than guessing.
- Buy soft cheese from the refrigerated case, take it home promptly, and return it to the fridge quickly after serving.
- Respect the sell-by and use-by dates, and plan to finish an opened container within a few days. Fresh cheese does not age gracefully in your fridge.
- Keep cheese away from raw meat juices, use a clean spoon or knife each time, and wash your hands before handling.
People in high-risk groups — pregnant women, adults 65 and older, anyone immunocompromised — should also avoid unpasteurized soft cheeses and check labels for pasteurization. If a product has expired or has been left out for hours, throw it out. When in doubt, the cheap, safe move is the bin. These habits fit the broader advice in our processed foods and gout guide, which covers how to judge ready-to-eat products that depend on cold storage. None of this changes the gout verdict on cheese. It just changes the way you buy, store, and eat it.
Frequently asked questions
Is requeson or soft cheese bad for gout?
No. Cheese is one of the safest dairy foods on a purine basis. In the FoodCanEat database, cheddar, mozzarella, Swiss, and grated parmesan each measure 0.0 mg purines per 100 g, all rated Safe, and fresh soft cheeses such as requeson fall into the same effectively purine-free band even though they have no separate entry. The 2026 Clover Hill outbreak was a bacterial contamination event, not a purine issue. If you have gout, soft cheese is not working against your urate. The two separate concerns are portion and handling: cheese still carries calories and sodium, and fresh soft cheese needs proper refrigeration. Treat the outbreak as a reminder about food safety, not as a reason to cross cheese off a gout-friendly plate.
Should I throw out my soft cheese after this outbreak?
That depends on what you have. The investigation points to Requeson and Soft Ricotta products from Clover Hill Dairy. If you have requeson from that producer, the cautious move is to discard it — or check the FDA and Food Safety News pages linked below for product details and follow those instructions. For other soft cheeses, check the sell-by date, confirm they were kept cold, and look for signs of spoilage such as off smells or slime. When any fresh dairy is in doubt, the safest choice is to throw it out. High-risk people — pregnant women, adults 65 and older, and anyone with a weakened immune system — should be especially strict and should ask a doctor if they have concerns. This is a food-safety decision, not a gout decision, and erring toward discarding is always low-cost.
How should I store requeson and other fresh soft cheeses?
Keep the refrigerator at or below 40°F (4°C), verified with a thermometer. In the store, take soft cheese from the refrigerated case and put it in the fridge at home promptly. Keep the container sealed, use a clean spoon or knife every time you dip in, and never leave the cheese out at room temperature for more than a couple of hours. Plan to finish an opened container within a few days of opening, and check the use-by date before each serving. Store cheese away from raw meat and poultry so juices cannot cross-contaminate. If the cheese develops an off odor, a changed texture, or visible mold, discard it. These are standard rules for any fresh dairy, and they apply to everyone — with extra strictness for pregnant women, older adults, and people with weakened immunity.
