Can Bun Cha Go Bad?

Bun Cha is a delicious Vietnamese dish made with grilled pork, rice noodles, and vegetables. It is a popular street food in Hanoi, and it is also becoming increasingly popular in other parts of the world.

However, like any other food, Bun cha can go bad if it is not stored properly. In this blog post, I will discuss how to tell if Bun cha has gone bad, and I will provide some tips for storing Bun cha so that it stays fresh and safe to eat.

How long will a Bun cha last?

The answer depends on how you store it.

If you store bun cha in the refrigerator:

  • Cooked pork patties: 3-4 days
  • Noodles: 3-4 days
  • Fresh vegetables: 2-3 days
  • Dipping sauce: 1-2 weeks

If you store bun cha in the freezer:

  • Cooked pork patties: 3-4 months
  • Noodles: 3-4 months
  • Fresh vegetables: 1-2 months
  • Dipping sauce: 6-8 months

It’s important to note that these are just estimates. The actual shelf life of bun cha will depend on a number of factors, including the freshness of the ingredients, the temperature of your refrigerator or freezer, and how well you store it.

You should also avoid storing bun cha at room temperature for more than 2 hours. This is because bacteria can grow rapidly at room temperature, and eating spoiled food can make you sick.

What will happen if you eat expired Bun cha?

If you eat an expired Bun cha, you may experience mild symptoms of food poisoning, such as nausea, vomiting, diarrhea, and stomach cramps. These symptoms usually start within a few hours of eating the spoiled food and may last for a few days.

In most cases, mild food poisoning is not serious and does not require medical attention. However, if you experience severe symptoms, such as high fever, bloody diarrhea, or difficulty breathing, you should seek medical attention immediately.

The risk of getting sick from eating slightly expired food depends on a number of factors, including the type of food, how long it has expired, and how it was stored.

Generally speaking, it is advisable to take the extra step of caution and toss any food that has gone bad.

Homemade vs store-bought Bun cha

The shelf life of Bun cha depends on how it is stored and whether it is homemade or store-bought.

Here is a table that summarizes the shelf life of Bun cha:

Type of Bun chaStorage method Shelf life
Homemade Bun cha Refrigerated 3-4 days
Homemade Bun cha Frozen 2 months
Store-bought Bun cha Refrigerated 4-5 days
Store-bought Bun cha Frozen 3 months

The shelf life of Bun cha is shorter if it is not stored properly. For example, if Bun cha is left out at room temperature for more than two hours, it should be discarded.

The impact of the ingredients on the shelf-life

Here are some of the ingredients in Bun cha and their impact on the shelf life of the dish:

  • Pork: Pork is a perishable food that can spoil quickly if not stored properly. The shelf life of pork in the refrigerator is 3-4 days, and it can be frozen for up to 6 months. However, the shelf life of pork in Bun cha will be shorter, as it is typically marinated in a sauce that contains vinegar and other ingredients that can speed up spoilage.
  • Rice noodles: Rice noodles are a shelf-stable food that can last for up to 1 year in the pantry. However, once they are cooked, they should be stored in the refrigerator and will only last for 3-4 days.
  • Vegetables: The shelf life of vegetables will vary depending on the type of vegetable. For example, leafy vegetables like lettuce will only last for a few days in the refrigerator, while root vegetables like carrots can last for up to 2 weeks.
  • Other ingredients: Other ingredients in Bun cha, such as the dipping sauce and herbs, will also have an impact on the shelf life of the dish. For example, the dipping sauce typically contains fish sauce, which can spoil quickly if not stored properly.

How to tell if your Bun cha has gone bad?

Here are some signs to look for:

  • The color has changed. Fresh bun cha should be a light pink color. If the pork patties have turned brown or gray, they have gone bad.
  • The texture has changed. Fresh bun cha should be firm and springy. If the pork patties are mushy or slimy, they have gone bad.
  • The smell is off. Fresh bun cha should have a pleasant, slightly sweet smell. If the pork patties have a sour, off-putting smell, they have gone bad.
  • There is mold or other growths on the food. If you see any mold or other growths on the pork patties, they have gone bad.

Should a Bun cha be refrigerated?

If you plan on eating your bun cha within a few hours of cooking, it’s okay to leave it out at room temperature. However, if you plan on storing it for longer than that, it’s best to refrigerate it.

Here are some reasons why you should refrigerate your bun cha:

  • To prevent bacteria from growing. Bacteria can grow quickly at room temperature, so refrigerating your bun cha will help to prevent it from going bad.
  • To keep the flavors fresh. The flavors in your bun cha will stay fresher longer if you refrigerate them.
  • To make it easier to reheat. If you refrigerate your bun cha, it will be easier to reheat later.

How long will Bun cha remain fresh in the fridge?

If you cook your bun cha at home, it will last for 3-4 days in the fridge. However, if you buy bun cha from a restaurant, it may only last for 2-3 days.

Here are some tips for keeping your bun cha fresh in the fridge:

  • Store it in an airtight container. This will help to prevent the flavors from escaping and the bacteria from growing.
  • Refrigerate it within 2 hours of cooking. This will help to prevent the bacteria from growing.
  • Label the container with the date you cooked the bun cha. This will help you to keep track of how long it’s been stored.

How can you reheat a Bun cha?

If you have leftover bun cha, you can reheat it in a few different ways. Here are a few methods:


  1. Place the bun cha in a microwave-safe dish.
  2. Cover the dish with a damp paper towel.
  3. Microwave on high for 1-2 minutes, or until heated through.


  1. Heat a pan over medium heat.
  2. Add the bun cha to the pan and cook for 2-3 minutes per side, or until heated through.


  1. Preheat the oven to 350 degrees Fahrenheit.
  2. Place the bun cha on a baking sheet.
  3. Bake for 10-15 minutes, or until heated through.

No matter which method you choose, be sure to reheat the bun cha until it is heated through. This will help to prevent any bacteria from growing.

How to keep your Bun cha fresh for days

Here are some tips on how to keep your Bun cha fresh for days:

  1. Use fresh ingredients. The fresher the ingredients, the longer your Bun cha will last. This is especially true for pork, which should be cooked thoroughly to kill any bacteria that could cause spoilage.
  2. Marinate the pork properly. The marinade will help to tenderize the pork and add flavor. It is important to use a good quality marinade that contains acidic ingredients, such as vinegar or lemon juice, as these will help to preserve the pork.
  3. Cook the pork evenly. The pork should be cooked until it is cooked through, but not overcooked. Overcooked pork will become dry and tough.
  4. Allow the Bun cha to cool completely before storing it. This will help to prevent the growth of bacteria.
  5. Store the Bun cha in an airtight container or zip-top bag. This will help to keep out air and moisture, which can cause spoilage.
  6. Label the container or bag with the date. This will help you to track how long the Bun cha has been stored.
  7. Store the Bun cha in the refrigerator. The refrigerator will keep the Bun cha fresh for 3-4 days.
