Eating leftover hot dogs cold is a common practice for many people. Hot dogs are often grilled, boiled, or microwaved to heat them up initially, but after cooking, they are easily stored in the refrigerator and eaten cold later. While hot dogs fresh off the grill can’t be beat, cold hot dogs are still a quick, convenient, and tasty snack for many. However, there are some health and safety concerns to consider when eating cold hot dogs.
Quick answers:
- It is generally safe to eat hot dogs cold if they have been properly handled, stored, and reheated.
- There are some health risks associated with cold hot dogs if they are contaminated with bacteria like Listeria or have not reached high enough temperatures when initially cooking.
- To minimize risks, hot dogs should be stored properly under refrigeration and reheated thoroughly before serving cold later.
- Some people may be more susceptible to illness from contaminated cold hot dogs, including pregnant women, young children, and those with weakened immune systems.
- As long as basic food safety precautions are followed, for most healthy adults, eating hot dogs cold poses a minimal risk.
How are hot dogs safely handled and prepared initially?
When hot dogs are first cooked, proper handling and preparation is key to safety. Here are some recommended guidelines for safely cooking hot dogs before refrigerating and eating them cold:
Purchase hot dogs from reputable brands and inspect packaging:
Purchase hot dogs from major, reputable national brands and inspect the packaging to ensure it is not expired, damaged, or tampered with. Avoid discolored or slimy looking hot dogs.
Cook hot dogs thoroughly to kill bacteria:
Hot dogs should be heated to 165°F internally to kill any potential pathogens like Salmonella or Listeria. Boiling, grilling, and microwaving are safe methods. Ensure they are cooked through and not still pink inside.
Do not cross-contaminate:
When handling raw hot dogs, be careful not to contaminate counter tops, utensils, and other foods. Wash hands and use separate plates/utensils for raw and cooked hot dogs.
Refrigerate promptly:
After cooking, hot dogs should be refrigerated within 2 hours, or 1 hour if in temperatures above 90°F. Rapid cooling prevents bacterial growth. Discard hot dogs left out longer.
How should you reheat and handle hot dogs to eat them cold?
Once hot dogs are cooked and refrigerated, food safety depends on proper reheating and handling when eating them cold later on:
Reheat hot dogs thoroughly before serving cold:
Always reheat hot dogs to 165°F before placing them in the refrigerator to cool and eat later. This kills any bacteria that may have grown during storage.
Cool hot dogs quickly before refrigerating:
Place hot dogs in shallow containers in refrigerator immediately after reheating so they can cool quickly. Do not let them sit at room temperature.
Observe safe refrigerator storage times:
Hot dogs should be eaten cold within 3-4 days if refrigerated at 40°F or below. Discard any leftovers after this timeframe.
Avoid cross-contamination when serving:
Use clean utensils and containers to serve reheated hot dogs. Do not reintroduce bacteria from hands, sinks, surfaces, or other foods.

What bacteria could pose issues in hot dogs?
There are some specific foodborne pathogens that can contaminate hot dogs and pose health risks if the hot dogs are then eaten cold later on:
Listeria monocytogenes:
Listeria is bacteria that can grow under refrigeration temperatures. It causes the illness listeriosis which can be serious in certain higher risk groups. Listeria is killed by thorough cooking to 165°F.
Salmonella:
Salmonella infection causes symptoms like diarrhea, fever, and cramps. It is also killed through cooking to 165°F. Cold hot dogs could be contaminated after cooking.
Staphylococcus aureus:
Staph bacteria produce toxins not destroyed by refrigeration. It is introduced through improper handling by people. Rare in commercial products.
Clostridium perfringens:
Causes diarrhea and cramps. Spores can survive cooking and grow back in cooled hot dogs if left too long at room or refrigeration temperatures.
Bacillus cereus:
Similar to C. perfringens, this causes diarrhea and vomiting by producing toxins. Proper refrigeration inhibits its growth.
Heating hot dogs to a safe internal temperature destroys these pathogens initially, but contamination can still occur afterwards, so reheating before eating cold is critical.
Who is more at risk from contaminated hot dogs?
While foodborne illness from hot dogs affects healthy adults less severely, some groups have higher susceptibility:
Pregnant women:
Illness can cause pregnancy complications. Listeria is especially concerning as it crosses the placenta and causes risks to the fetus.
Young children:
Kids’ underdeveloped immune systems make them more vulnerable. Pathogens like E. coli O157:H7 and Salmonella hit them harder.
Elderly:
Weakened immunity in older adults makes it harder to fight infection. Dehydration from vomiting and diarrhea is also a major concern.
Those with chronic diseases:
People managing illnesses like diabetes, cancer, kidney disease, and autoimmune disorders are at increased risk of severe complications from foodborne illness.
Those with compromised immunity:
Transplant patients, HIV/AIDS patients, chemotherapy patients, and others with weakened immune systems due to illness or medication can become very sick from pathogens like Listeria. Special caution is needed.
While healthy adults get through hot dog-associated illness more easily, caution is still recommended. Vulnerable groups should take extra care or avoid higher risk foods like cold hot dogs.
What are the possible symptoms and health risks?
Bacteria from contaminated cold hot dogs can cause the following symptoms and complications in those infected:
Digestive issues:
Diarrhea, vomiting, nausea, cramps, and abdominal pain are common symptoms with hot dog-related illness from Salmonella, E. coli, Listeria, Staph, Clostridium, and Bacillus bacteria.
Fever and flu-like symptoms:
Pathogens can cause fever, body aches, chills, headache, weakness, and fatigue in many types of foodborne illness.
Dehydration:
Excessive fluid loss from repeated vomiting and diarrhea can cause dangerous dehydration, especially in children, elderly, and those with chronic diseases.
Hospitalization:
In severe cases, acute infection may require hospital care to treat dehydration, fever, diarrhea, and other symptoms through IV fluids, medications, etc.
Long-term complications:
Listeria can cause miscarriage, stillbirth, or infant sepsis if contracted while pregnant. E. coli O157:H7 and Salmonella can lead to chronic conditions like reactive arthritis, kidney problems, and irritable bowel syndrome.
While most recover fully in a few days, contaminated cold hot dogs should not be taken lightly, as foodborne illnesses can sometimes cause severe, lasting complications.
How can you reduce your risk when eating hot dogs cold?
Here are some tips to stay safe and lower your risk of foodborne illness when eating hot dogs cold:
- Cook hot dogs to 165°F initially to kill all pathogens.
- Don’t let cooked hot dogs sit out for more than 2 hours before refrigerating.
- Divide hot dogs into shallow containers for quick cooling in the refrigerator.
- Reheat hot dogs thoroughly to 165°F before placing back in the fridge to cool.

Following food safety guidelines strictly, using proper cooking and storage methods, practicing good personal hygiene, and monitoring for product recalls can all help minimize the risks involved with eating hot dogs cold.
Are there any precautions pregnant women should take?
Listeria infection from cold hot dogs poses a significant health threat during pregnancy. Here are some special precautions pregnant women can take:
- Avoid eating cold hot dogs unless thoroughly reheated to steaming immediately before.
- Do not eat cold hot dogs that have been sitting in the refrigerator for more than 2-3 days.
- Reheat deli-style hot dogs from counters and salad bars to steaming hot before cooling and eating.
- Avoid cross-contamination by keeping raw meats like hot dogs away from ready-to-eat foods.
- Use a food thermometer to verify hot dogs reach safe internal temperatures when cooking.
- Do not eat hot dogs that look or smell spoiled or questionable.
- Consider avoiding higher risk foods like hot dogs if you have a compromised immune system.
Pregnant women are safest avoiding cold hot dogs, but if choosing to eat them, following these precautions very strictly can help lower risks. Always discuss with your doctor as well.
Can hot dogs be safely microwaved to reheat?
Yes, hot dogs can be safely reheated in the microwave as long as proper precautions are taken:
- Make sure there is no aluminum foil or metal in the microwave.
- Cook hot dogs in short intervals like 30 seconds to distribute heat evenly.
- Rotate or rearrange hot dogs at least once during microwaving.
- Allow standing time. Internal temperature will still rise slightly after removing from microwave.
- Verify internal temperature reaches 165°F by inserting a clean thermometer in thickest part.
- Cover hot dogs while microwaving to hold in moisture and ensure even heating.
- Stir or break up any cold spots and return to microwave if needed to reach safe 165°F temperature.
With these steps, microwaving can safely reheat hot dogs to control bacterial growth before placing them back in the refrigerator to eat cold. Just be sure to verify the proper internal temperature.
Conclusion
Eating hot dogs cold can be done safely by most healthy adults if they are handled according to recommended guidelines. The most important points are to fully cook hot dogs initially to destroy pathogens, prevent cross-contamination after cooking, promptly refrigerate, reheat thoroughly before serving cold, observe safe refrigerator storage times, and handle hygienically.
Those in higher risk groups like pregnant women, infants, elderly, or immunocompromised individuals may want to take extra care or avoid higher risk foods like cold hot dogs. While leftovers always carry some level of risk, following proper food safety practices can greatly reduce the chances of illness. Reheating hot dogs to a safe internal temperature of 165° is perhaps the most critical step to minimize any hazards when eating hot dogs cold.
