Does cooking kill salmonella? Yes, proper cooking can destroy Salmonella bacteria when food reaches a sufficiently high internal temperature. But simply heating food, browning its surface, or cooking it for a certain amount of time does not always guarantee safety. The center of the food needs to reach the appropriate temperature, and recalled food should never be considered safe simply because it can be cooked.
The question has added importance in the United States as federal health officials continue investigating a multistate Salmonella outbreak associated with jalapeño peppers. The latest update shows 431 illnesses across 32 states, with 57 hospitalizations and no reported deaths. The investigation and related recalls remain active.
Understanding how heat affects Salmonella can help consumers make safer decisions when preparing meat, poultry, eggs, leftovers and other foods at home.
How Heat Destroys Salmonella
Salmonella is a group of bacteria that can cause salmonellosis, a foodborne illness. The bacteria can be present in raw or contaminated foods without changing the food’s appearance, smell or taste.
Heat can destroy the bacteria when food receives enough heat for a sufficient amount of time.
That does not mean every food becomes safe simply because it feels hot. A thick piece of chicken, for example, may become browned on the outside while the center remains below a safe temperature.
This is why internal temperature matters more than the temperature of the oven, grill or cooking oil.
A food thermometer provides a much better indication of safety than appearance alone.
The Safe Temperatures That Matter Most
Different foods require different minimum internal temperatures. The recommended temperatures used in U.S. food-safety guidance include:
| Food | Minimum Internal Temperature |
|---|---|
| Poultry, including chicken and turkey | 165°F |
| Ground beef, pork, lamb and veal | 160°F |
| Ground poultry | 165°F |
| Egg dishes | 160°F |
| Fish and shellfish | 145°F |
| Whole cuts of beef, pork, lamb and veal | 145°F, followed by a 3-minute rest |
| Leftovers | 165°F |
These temperatures are measured inside the food rather than on the surface.
For thicker foods, check the center or thickest portion. For poultry, avoid placing the thermometer directly against bone because it can produce an inaccurate reading.
Why Chicken Needs 165°F
Chicken and turkey are among the foods where careful temperature control is particularly important.
Raw poultry can carry Salmonella and other harmful microorganisms. Cooking poultry to 165°F provides the recommended safety target for home preparation.
A common mistake is judging chicken by its color.
White meat can appear fully cooked before the center reaches the recommended temperature. At the same time, properly cooked chicken does not always have to look exactly the same shade throughout.
A thermometer provides a more dependable answer.
Insert it into the thickest section of the meat. For a whole chicken or turkey, check several areas to make sure the bird has reached the appropriate temperature.
Ground chicken and turkey also need to reach 165°F because grinding distributes material throughout the product.
Can Cooking Destroy Salmonella in Ground Beef?
Yes. Cooking ground beef to 160°F can destroy Salmonella and other harmful bacteria when the temperature is reached throughout the patty.
Ground meat deserves special attention because bacteria on the outside of a whole cut can become distributed throughout the product when the meat is ground.
That means a burger cannot be judged safe simply because the outside looks well browned.
Insert a food thermometer into the thickest part of the patty. For thin burgers, inserting the thermometer from the side can make it easier to measure the center.
Ground pork, lamb and veal also have a 160°F minimum temperature.
What About Steak and Other Whole Cuts?
Whole cuts of beef, pork, lamb and veal have a recommended minimum internal temperature of 145°F, followed by a three-minute rest.
The thermometer should be inserted into the thickest portion.
The resting period is part of the federal recommendation. It gives the meat time to remain at a high temperature after leaving the heat source.
The same approach should be used when preparing roasts and chops.
Does Cooking Kill Salmonella in Eggs?
Proper cooking can destroy Salmonella in eggs and egg dishes.
For dishes containing eggs, 160°F is the recommended minimum internal temperature.
For shell eggs, cooking until the yolk and white are firm is an important safety practice.
Eggs can present a challenge because some recipes intentionally use raw or lightly cooked eggs. Homemade sauces, desserts and other preparations can contain eggs that do not receive enough heat to reliably destroy bacteria.
Pasteurized eggs or pasteurized egg products can be used when a recipe calls for raw or lightly cooked eggs.
The key issue is whether the egg receives sufficient treatment to control Salmonella.
Does Baking Kill Salmonella?
Baking can destroy Salmonella when the food reaches a safe internal temperature.
One important misconception is that setting an oven to a high temperature automatically makes every food safe.
The oven temperature and the internal food temperature are not the same.
A large casserole can take considerable time to heat through. The surface may become hot long before the center reaches the necessary temperature.
Egg dishes should reach 160°F. Casseroles containing poultry or other ingredients requiring higher temperatures should be cooked to the appropriate temperature for the food.
Using a thermometer is especially useful for thick baked dishes.
Does Frying Kill Salmonella?
Frying can destroy Salmonella when the food reaches the necessary internal temperature.
The temperature of the oil, however, does not tell you whether the food’s center has reached a safe temperature.
This matters with fried chicken, breaded chicken products, burgers and other thick foods.
A piece of food can develop a crisp, browned coating while remaining undercooked inside.
Checking the thickest part with a food thermometer provides a much better safety check.
Does Boiling Kill Salmonella?
Boiling temperatures are high enough to destroy Salmonella, but the important question is whether the contaminated portion of the food actually receives sufficient heat.
This is usually straightforward with liquids because heat can circulate throughout the product. Solid foods can be more complicated.
A large piece of meat placed into hot liquid may have a center that remains much cooler than the surrounding water.
Food size, shape and density all affect how quickly heat travels toward the center.
When a specific internal temperature applies, checking the food itself remains the safest approach.

Does Microwaving Kill Salmonella?
Microwave cooking can destroy Salmonella when food becomes sufficiently hot throughout.
The challenge is uneven heating.
Microwaves can create hot and cold areas, particularly in thick or irregularly shaped foods. A dish may feel extremely hot in one location while another area remains cooler.
When reheating food in a microwave, stir or rotate it when appropriate. Allow heat to distribute, then check the temperature in multiple areas.
Leftovers should reach 165°F.
This is especially important for dense dishes such as casseroles, soups containing large pieces and prepared meals.
Does Cooking Kill Salmonella on Vegetables?
Cooking can destroy Salmonella on vegetables when sufficient heat reaches the contaminated areas.
However, many vegetables are eaten raw.
That means consumers cannot depend on cooking to eliminate bacteria from foods such as raw peppers, lettuce or other produce that is served without a cooking step.
This issue is particularly relevant during the current U.S. jalapeño outbreak.
Federal investigators have connected the outbreak to jalapeños from Sinaloa, Mexico, distributed by Coast Citrus Distributors. The latest federal update reports 431 illnesses across 32 states.
Consumers should follow recall instructions for affected products rather than attempt to make recalled peppers safe by cooking them.
Why Cooking Does Not Make Recalled Food Safe to Eat
This distinction is critical.
Proper cooking can destroy Salmonella in food under controlled conditions. It does not mean consumers should cook a recalled product and then eat it.
When authorities issue a recall because a product may contain Salmonella, consumers should follow the instructions provided with that recall.
The current jalapeño investigation is a clear example. Federal officials have advised consumers not to eat, serve or sell recalled fresh jalapeños or products containing recalled peppers.
Cooking should not be viewed as a way to override a recall.
Handling recalled food can also spread contamination to hands, cutting boards, knives, countertops and refrigerator surfaces.
If a recalled item has been stored in the home, consumers should follow the applicable disposal or return instructions and clean surfaces that may have contacted it.
The Latest U.S. Salmonella Situation
The current jalapeño outbreak has increased the relevance of food-safety questions across the country.
The latest update reports:
- 431 illnesses
- 32 affected states
- 57 hospitalizations
- No reported deaths
- Illnesses reported between June 19 and August 2, 2026
The outbreak involves Salmonella Javiana.
Federal investigators identified jalapeños from Sinaloa, Mexico, distributed by Coast Citrus Distributors as the source connected to the investigation.
Some affected peppers were used in other foods, leading to additional recalls.
This situation highlights an important point: food safety starts before the cooking stage. If a product has been recalled, consumers should not attempt to solve the problem with additional heat.
Can Freezing Kill Salmonella?
Freezing should not be considered a reliable way to eliminate Salmonella.
Low temperatures can stop or slow bacterial growth, but freezing does not provide the same control as proper cooking.
A contaminated product can remain a food-safety concern after being frozen.
This is why recalled foods should be discarded or returned according to the recall instructions even if they have been stored in a freezer.
Freezing is a storage method, not a substitute for pathogen control.
Can Washing Remove Salmonella?
Washing also does not guarantee that Salmonella will be eliminated.
For raw meat and poultry, rinsing is discouraged because splashing water can spread bacteria around the kitchen.
The bacteria can reach sinks, counters, cutting boards, utensils and nearby foods.
Fresh produce should be handled carefully and rinsed under running water when appropriate, but washing should not be treated as a guarantee that every harmful microorganism has been removed.
Cooking remains an important control step for foods intended to be cooked.
Cross-Contamination Can Undo Safe Cooking
Even when food reaches the right temperature, Salmonella can be transferred back onto it afterward.
Consider a simple kitchen sequence.
Raw chicken is placed on a cutting board. The board then holds cooked chicken without being washed.
Bacteria from the raw chicken can transfer to the cooked food.
The same problem can occur when a clean plate is used for raw meat and then used again for cooked food.
Hands can also transfer bacteria between raw and ready-to-eat foods.
To reduce this risk, keep raw meat and poultry separate from foods that will not be cooked. Wash hands, utensils and preparation surfaces after contact with raw ingredients.
Why Food Thermometers Are So Important
A food thermometer removes much of the guesswork from cooking.
Color is unreliable. Texture is unreliable. Cooking time can vary.
A thermometer measures what actually matters: the internal temperature.
For poultry, place the probe in the thickest portion. For burgers, check the center. For roasts, insert the probe into the thickest section without touching bone.
Clean the thermometer after checking raw food and before using it on cooked food.
A simple temperature check can prevent the mistake of serving food that looks finished but has not reached the recommended internal temperature.
What Happens If Salmonella Is Consumed?
Salmonella infection commonly causes diarrhea, fever and stomach cramps.
Some people also experience nausea, vomiting or other digestive symptoms.
Symptoms can begin several hours to several days after exposure.
Most people recover without specific treatment, but Salmonella can sometimes cause serious illness.
Children younger than 5, adults 65 and older, and people with weakened immune systems have a greater risk of severe disease.
Anyone who develops concerning symptoms after eating a recalled product should seek medical advice and mention the suspected food exposure.
Safe Cooking Is More Than Reaching a Temperature
Temperature is essential, but it is not the only protection.
A safe kitchen routine also involves preventing contamination before and after cooking.
Keep raw foods separate. Wash hands and surfaces. Use clean utensils for cooked food. Refrigerate perishable items promptly.
Food should not sit at room temperature for extended periods.
Refrigeration slows bacterial growth, while proper cooking provides the heat needed to destroy harmful bacteria.
Together, these practices create stronger protection than relying on cooking alone.
The Bottom Line
Proper cooking can destroy Salmonella when food reaches the appropriate internal temperature. Poultry should reach 165°F, ground meats generally require 160°F, egg dishes should reach 160°F, whole cuts of meat should reach 145°F followed by a three-minute rest, and leftovers should reach 165°F.
But cooking cannot replace a recall notice. Consumers should never assume that a recalled product becomes safe simply because they can heat it.
The ongoing U.S. jalapeño outbreak reinforces that distinction. Safe food preparation requires attention to internal temperature, handling, storage, cross-contamination and current recall information.
