Food poisoning is an unpleasant and often dangerous experience, affecting millions of people in the U.S. each year. While many assume that contaminated food is mostly a problem in restaurants, the truth is that foodborne illnesses can strike in a variety of places—including homes, schools, catered events, and even cruise ships. Certain locations pose a higher risk due to large-scale food preparation, improper handling, or extended food storage at unsafe temperatures.
From buffet-style restaurants where cross-contamination is a constant threat to fast food chains where rapid service can lead to food safety lapses, outbreaks can happen anywhere food is mishandled. Whether it’s a wedding banquet, a school cafeteria, or a sit-down restaurant, knowing which places carry the highest risk of foodborne illness can help you take precautions. Here’s a look at the top 10 most common places to get food poisoning in the U.S., ranked from least to most likely.
10. Cruise Ships
While cruise ships offer luxurious dining experiences, they are also known for occasional foodborne illness outbreaks. The confined environment, communal dining, and shared kitchen facilities make it easier for viruses and bacteria to spread rapidly. One of the most common culprits is norovirus, which causes severe gastrointestinal distress and spreads quickly through contaminated food, surfaces, and even person-to-person contact.
Buffet-style dining, which is common on cruises, further increases the risk of cross-contamination. While cruise lines follow strict sanitation protocols, a single lapse in food handling or hygiene can lead to large-scale outbreaks, affecting hundreds of passengers. Travelers can reduce their risk by practicing good hand hygiene and avoiding foods that have been sitting out for extended periods.
9. Community Events (Fairs, Festivals, and Potlucks)
Foodborne illnesses often occur at public gatherings such as fairs, festivals, and potluck events, where food safety regulations may be more relaxed or difficult to enforce. At these events, food is frequently prepared in bulk by volunteers or vendors who may not have formal food safety training. Common risks include improper storage, inadequate handwashing, and cross-contamination between raw and cooked foods.
Additionally, food at these events is often left at unsafe temperatures for long periods, allowing bacteria to multiply rapidly. Many outbreaks at fairs and potlucks have been linked to dishes like potato salad, which can harbor Salmonella or Listeria if not kept cold. Attendees can reduce their risk by choosing hot foods that are freshly cooked and avoiding perishable items that have been sitting out too long.

8. Correctional Facilities
Prisons and jails are another high-risk setting for foodborne illness outbreaks due to large-scale food preparation, limited resources, and sometimes questionable food handling practices. Food in correctional facilities is often prepared in bulk, increasing the likelihood of contamination if proper safety procedures are not followed. Additionally, many facilities rely on processed or preserved foods that may be stored for long periods, creating a risk for bacterial growth if not handled correctly.
In some cases, poor kitchen sanitation, rodent infestations, and the reuse of old or expired food ingredients have contributed to major outbreaks of illnesses such as Clostridium perfringens and E. coli. While inmates have little control over food preparation, advocacy for improved food safety standards and oversight has led to gradual improvements in some institutions.
7. Healthcare Facilities (Hospitals and Nursing Homes)
Hospitals and nursing homes serve vulnerable populations, making food safety a critical concern. Patients and elderly residents often have weakened immune systems, making them more susceptible to severe complications from foodborne illnesses. Despite stringent regulations, outbreaks can still occur due to improper food handling, contaminated produce, or unclean kitchen equipment. Listeria, Norovirus, and Salmonella have all been linked to hospital foodborne illness outbreaks.
Nursing homes, in particular, have been identified as hotspots for food-related illnesses because of challenges in maintaining strict food safety protocols. Since many residents rely on pre-prepared meals, there is a risk of contamination during storage and reheating. To minimize these risks, healthcare facilities must follow rigorous sanitation and food preparation standards to ensure the safety of their patients and residents.
6. School Cafeterias
School cafeterias serve meals to millions of children daily, making them a potential source of foodborne illnesses. While most school lunch programs adhere to strict safety guidelines, mistakes can still happen. Contaminated ingredients, improper food storage, or insufficient cooking can lead to outbreaks of E. coli, Salmonella, and Norovirus. Because children’s immune systems are still developing, they are particularly vulnerable to food poisoning.
A single lapse, such as serving undercooked chicken or using tainted lettuce in a salad, can sicken dozens of students. Additionally, budget constraints in some school districts may lead to outdated food handling practices or reliance on lower-quality food sources. Schools can mitigate risks by ensuring staff receive proper food safety training and by closely monitoring food suppliers and preparation methods.
5. Buffet-Style Restaurants
Buffets are popular dining spots due to their variety and unlimited servings, but they also come with a higher risk of food poisoning. The primary concern with buffets is that food sits out for extended periods, often at unsafe temperatures that promote bacterial growth. Additionally, self-serve stations mean that customers frequently handle serving utensils, increasing the potential for cross-contamination. Food items like seafood, dairy-based salads, and meats can become breeding grounds for bacteria if they are not maintained at the correct temperatures.
Moreover, when new batches of food are added to existing trays (a practice known as “top-off” serving), any contamination present in the original food can spread to the fresh batch. Restaurants must be diligent in replacing food frequently, monitoring temperatures, and ensuring strict hygiene practices to prevent outbreaks.
4. Fast Food Chains
Fast food restaurants are a common source of food poisoning outbreaks due to the sheer volume of food prepared and served daily. While major chains follow standardized safety protocols, human error can lead to contamination issues. Cross-contamination between raw and cooked food, undercooked meat, and unsanitary food handling practices are among the top concerns. In the past decade, major fast-food chains such as McDonald’s, Chipotle, and Taco Bell have been linked to large outbreaks of E. coli, Salmonella, and Norovirus.
The fast-paced nature of these establishments can sometimes result in shortcuts in hygiene or improper storage of ingredients. Consumers can reduce their risk by ensuring their food is fully cooked and by avoiding high-risk items like undercooked meats and pre-cut vegetables that may have been sitting out for too long.
3. Private Homes
Surprisingly, one of the most common places for food poisoning is the home kitchen. Many people assume home-cooked meals are safer than restaurant food, but improper food handling practices at home contribute to a large percentage of foodborne illness cases. Common mistakes include failing to wash hands, cross-contaminating raw and cooked foods, improperly storing leftovers, and undercooking meat or eggs.
Unwashed fruits and vegetables, expired dairy products, and improperly canned foods also pose significant risks. Since home kitchens do not have the same oversight as restaurants, individuals must take extra precautions when preparing meals. Simple habits such as using separate cutting boards for raw meats, refrigerating leftovers promptly, and cooking food to the correct temperature can significantly reduce the risk of food poisoning at home.

2. Catering Events (Weddings, Banquets, and Conferences)
Catering events are among the most common settings for large-scale food poisoning outbreaks. These gatherings often involve mass food preparation, sometimes hours before serving, which increases the risk of bacterial growth. Common issues include improper refrigeration, undercooked meats, and contamination during food transport. Buffet-style serving also presents risks, as guests may unknowingly spread bacteria by handling utensils or leaving food out for too long.
One well-known example is the frequent outbreaks linked to wedding receptions, where improperly stored seafood or dairy-based dishes have sickened dozens of attendees. To prevent illness, catering companies must adhere to strict food safety guidelines, including maintaining proper food temperatures, using sanitized equipment, and ensuring thorough cooking of all ingredients.
1. Sit-Down Restaurants
Sit-down restaurants are the most common place for food poisoning cases in the U.S. While the majority of restaurants follow strict health codes, violations do occur, leading to outbreaks. The most frequent causes of illness include cross-contamination, improper food storage, and sick employees handling food. Many outbreaks are linked to undercooked meat, contaminated produce, and poor kitchen sanitation. Even high-end restaurants are not immune, as contamination can occur at any point in the supply chain, from sourcing ingredients to final preparation.
Reports from health departments indicate that restaurants account for a large portion of foodborne illness outbreaks each year, making them the top setting for food poisoning. Diners can protect themselves by choosing establishments with good hygiene ratings, ensuring their food is fully cooked, and being mindful of any unusual smells or appearances in their meals.
