Tips

You’ve been craving some warm, fluffy rice for dinner. It’s finally time to prepare your meal but… you see some small maggots crawling around the rice bag. Yuck! It’s common to see these worm-like creatures in your pantry. Like us, maggots love dry foods like cereal, spices, and rice, and there’s been a lot of speculation on whether rice turns into maggots. Although the grain doesn’t actually transform into these critters, keep reading to figure out how they keep appearing in all of our favorite pantry foods!

Things You Should Know

Rice does not turn into maggots! Insects lay their eggs on rice grains, and the eggs hatch into larvae (known as maggots).
Maggots are usually hidden inside the rice grains. If you suspect your rice is contaminated, place the bag in the freezer for 4 days to kill any eggs or larvae.
It’s safe to eat maggots in rice, as long as the rice is properly cooked.

Rice does not transform into maggots. Rice is a grain, so it cannot turn into a live insect. However, rice is an ideal breeding ground for insects. Insects lay their eggs on rice grains. Once the eggs hatch into larvae (known as maggots), the larvae have an instant food source, they reproduce, and the cycle repeats.^{[1]XResearch source}
- Most “maggots” found in rice aren’t actually maggots! True maggots come from fly eggs, but the most common pantry pest is the Indian meal moth. Since both insects have similar-looking larvae, Indian meal moth larvae are still referred to as maggots.
- Indian meal moth eggs hatch into small white caterpillars about .5 inches (1.3 cm) long. Fully-grown larvae can also have a green or pinkish hue.^{[2]XResearch source}

Insect eggs hide inside grains when the rice is processed. It’s impossible to grow and process food that’s 100% pest-free.^{[3]XTrustworthy SourceUS Food and Drug AdministrationU.S. government agency responsible for promoting public healthGo to source} When rice is processed, insect eggs hide in the grains. These eggs are nearly impossible to detect, so most maggots come directly from the manufacturer.^{[4]XResearch source}
- Depending on when the eggs were laid, you may purchase rice that already contains visible maggot larvae, or the eggs will hatch a few weeks later (if you store your rice at room temperature).
- Inspect rice packaging at the supermarket to avoid purchasing potentially infested rice. If there are any holes or tears in the packaging, choose another bag of rice!

Improper storage allows insects to lay eggs on your rice. Maggot infestation easily occurs from improper rice storage. It’s important to store your rice in an airtight container, preventing insects from laying their eggs in the first place.
- Avoid storing your rice in thin plastic bags or cardboard–maggots can chew through these materials! Keep all your pantry items, including rice, in a tightly-sealed container made out of metal, glass, or thick plastic.^{[5]XResearch source}

Is it safe to eat rice with maggots?

With proper cooking, you can eat rice that contains maggot eggs/larvae. In some parts of the world, maggot larvae are considered a delicacy (and a good source of protein). Maggots pose a greater health risk when they’re found in fresh or pre-cooked foods. Since rice grains are boiled before consumption, the hot water kills the insect eggs/larvae. Just be sure to cook your rice for at least 5 minutes!^{[6]XResearch source}
- There’s a slim possibility that larvae can cause myiasis, a condition where surviving larvae enter the stomach and/or intestines. It’s typically not life-threatening, but it can cause vomiting, nausea, or stomach pains.^{[7]XResearch source}
- If your (dry) rice contains maggots, you don’t have to throw it out! Check the expiration date on the rice packaging to ensure it’s still fresh–spoiled food leads to food poisoning, rather than maggots.

Spread the rice evenly on a sheet tray and heat it with a hair dryer. Make sure the sheet tray is large enough so there is only one flat layer of rice. On high-heat, run a hair dryer over your rice (2-3 times) to thoroughly heat the grains. Concentrate on spots that show discoloration or movement.^{[8]XResearch source}
- If you don’t have a hair dryer, pour boiling water over the rice to kill the maggots and wait 5 minutes. Maggots cannot survive extreme temperatures, so you can cook the rice after draining the water.
Dump the rice from the sheet into a bowl and let it rest for 5 minutes. Add the boiling water and wait a few minutes for the maggot larvae to rise to the surface of the water. Use a small cup to scoop them out and immediately cook the soaked rice to avoid bacterial growth.^{[9]XResearch source}

Make sure you freeze your rice grains at a temperature of 0℃. If you buy a bulk bag of rice, divide it into smaller bags before freezing to ensure enough cold air movement reaches all of the grains.^{[10]XResearch source}
For long-term storage, pour your rice in a food-grade container that has been lined with a Mylar bag. The best temperature to store rice is 40℉ or below, but properly-stored rice can last up to 10 years at a constant temperature of 70℉.^{[11]XResearch source}
3
Add food-safe oxygen absorbers in your rice bag to kill maggot eggs. Oxygen absorbers are small square packets commonly found in snacks like beef jerky. They preserve the shelf life of food by removing oxygen inside their packaging, but they’re also perfect to prevent insect eggs from hatching!
- Oxygen absorbers are usually labeled with “do not eat” or “do not microwave” so make sure to remove them before cooking your rice.

Expert Answer
Various insects and pests feed on rice, considering it a valuable food source. Among them are black bugs and rice weevils. Black bugs are a common pest in rice fields, capable of causing significant damage to crops. These insects feed on rice plants at various stages of growth, from seedlings to mature grains, often leading to yield losses if left unchecked. Rice weevils, on the other hand, are notorious for infesting stored rice grains. They lay eggs inside the rice kernels, and the hatched larvae consume the grain from within, rendering it unfit for consumption. Controlling these pests is essential for safeguarding rice production and preserving grain quality.

Brown rice has a shorter shelf life than white rice because its outer layer contains more oil. Store brown rice in the refrigerator to extend its shelf life.^{[12]XResearch source}
