I’ve been on a carnivore diet for over a decade, and I can’t even count how many times I’ve left ham out during this time. I wanted to check if the ham left out was safe to eat, so I checked what the USDA says about the leftover cooked ham and consulted my local butcher.
Here’s everything you should know about how long ham can sit at room temperature and how to tell if it’s gone bad.
Quick Summary
- You shouldn’t leave cooked food sitting at room temperature for more than two hours.
- You can keep ham for four days in the fridge and frozen ham for two months in the freezer.
- You can do smell and taste tests to check if the ham is spoiled.
How Long Can Ham Sit Out?

Ham can sit out for two hours before going bad, according to the USDA and CDC [1] [2]. Food left at a temperature between 40 degrees and 140 degrees is at risk of growing harmful bacteria at a fast rate.
You also shouldn’t leave ham to sit overnight, both cooked or raw. If ham sits at a temperature above 40 degrees for a long time, it can develop bacteria. When you consume ham that’s been left overnight, you risk being exposed to bacteria and getting food poisoning.
The shelf life of cooked ham depends on how you store it. Same as raw ham, it’ll stay fresh at room temperature for two hours. However, if the temperature is 90 degrees in summer, the ham will stay fresh for only one hour.
Ham stored in a bag or a damp tea towel will stay fresh for up to four days in the fridge or up to two months in the freezer in food storage containers [3].
It can be challenging not to leave cooked meat at room temperature, especially when you have family or friends over, such as on holidays.
But, you should make sure to store cooked ham, sliced ham, smoked ham, or honey-baked ham within the two hours it’s been exposed to room temperature. This way, you'll have leftover ham you can eat in the coming days.
Overall, stick to the two-hour guideline, whether you have cooked food or raw.
“Bacteria can grow rapidly in the danger zone between 40°F and 140°F. After food is prepared, keep hot food hot and cold food cold. Refrigerate or freeze perishable food like meat, chicken, turkey, seafood, eggs, cut fruit, cooked rice, and leftovers within 2 hours (1 hour if food is exposed to temperatures above 90°F, such as in a hot car).”

How to Tell Ham Has Gone Bad?
You can tell your ham has gone bad by doing sight and smell tests. You should also follow this rule: if you leave the ham overnight, toss it.
Spoiled ham will have changes in texture and color.
For example, if ham sits outside for an extended time, it’ll have a grayish tone and a slimy or sticky residue. These are the signs it’s spoiled. Moreover, the spoiled ham will have a noticeable odor. If your cured ham smells foul, don’t eat it.
Also, be careful with re-cooking ham if it’s gone bad. There’s a popular belief that you can serve ham that’s gone bad if you cook it again.
However, this is untrue, and re-cooking the ham or heating it won’t make it safe again. While it's true that heat kills bacteria, the heat doesn’t remove poisonous toxins that the bacteria leave behind.
Overall, if you leave smoked foods sitting for hours, don’t reheat or re-cook, or you risk getting food poisoning.

What Is the Best Way to Store Ham?

The best way to store ham is to freeze it or store it in the fridge.
Here are some tips on storing cooked foods, especially ham:
- Keep it warm — If you’re serving a holiday meal or a dinner that will last for hours, don’t let smoked ham sit for too long. Instead, use a chafing dish or a slow cooker to keep it warm. The temperature should be above 140 degrees to prevent bacteria growth.
- Wrap it — If you want to eat cooked ham left over in the coming days, let it cool down, wrap it tightly, and store it in the fridge. You can wrap it in a ham bag or a damp tea towel so it doesn’t dry out.
- Store in the fridge — Place the sliced ham in an airtight container. Check that ham is completely cooled down before placing it in the fridge. This prevents the fridge temperature from rising, which can make harmful bacteria grow.
- Store in the freezer — If you want to use ham later on, put it in the freezer. Freeze separate portions of the pre-cooked ham so you don’t have to thaw the whole piece at once. Store ham in an airtight container so the cold air doesn’t touch the meat. This prevents freezer burn. If you have unopened country-style hams, always freeze them in the original packaging.
When you want to thaw ham, move it from the freezer to the fridge. Put the ham in a bowl or a tray to catch drips, and leave it overnight. Never let ham thaw overnight at room temperature, or it’ll develop bacteria.

Also, be careful where you buy ham. For the past two years, I’ve been ordering ham from ButcherBox, an online meat delivery that sells high-quality, responsibly raised cuts.
They sell grass-fed beef, heritage-bred pork, and poultry that’s raised crate-free. Their meat is hormone and antibiotic-free, so you can rest assured your meat bears no health risks.
