Eggs are a staple in many diets and are often praised for their nutritional value. However, there has been some concern about the potential risk of contracting worms from consuming chicken eggs. Can humans really get worms from eating eggs? In this article, we will explore the possibility of egg-borne worm infections and provide tips on how to properly handle and cook eggs to reduce this risk. Keep reading to find out more.

Can Humans Get Worms from Chicken Eggs?

Chicken eggs are a staple food in many households, and for good reason. They are a great source of protein, vitamins, and minerals. However, in recent years there have been concerns about the safety of consuming chicken eggs. One of the biggest concerns is whether or not humans can contract worms from these eggs.

In short, the answer is yes, humans can get worms from chicken eggs. But, there are specific ways to reduce the risk and ensure the eggs you consume are safe. In this article, we will explore the types of worms found in chicken eggs, how they can be transmitted to humans, and the proper handling and cooking techniques to minimize the risk of contracting worms.

Types of Worms Found in Chicken Eggs

The most common type of worm found in chicken eggs is the roundworm, specifically, the Ascaris lumbricoides. These worms can grow up to 35 cm long and live in the intestines of chickens. They lay eggs that are then released into the chicken’s feces and can contaminate the egg if it is not cleaned properly.

Another type of worm that can be found in chicken eggs is the tapeworm. Chickens can become infected with tapeworms by ingesting insects or other small organisms that carry the tapeworm larvae. These larvae can then develop into adult worms in the intestines of chickens and potentially contaminate their eggs.

Both roundworms and tapeworms are parasites that can cause health issues if consumed by humans. Roundworms can migrate to different parts of the body and cause complications like intestinal blockages, while tapeworms can lead to vitamin deficiencies and weight loss. The severity of these health issues depends on the number of worms ingested and the individual’s immune system.

How Can Humans Get Worms from Chicken Eggs?

Humans can get worms from chicken eggs if the eggs are not handled or cooked properly. As mentioned earlier, chicken eggs can become contaminated with worm eggs through the feces of infected chickens or by ingesting insects carrying tapeworm larvae. This is why it is important to ensure the eggs are clean and free of any contamination before consuming them.

If a chicken has roundworms or tapeworms, the eggs they lay can contain their eggs as well. When these contaminated eggs are consumed raw or undercooked, the worm eggs can infect humans. The most common way for this to happen is by consuming eggs in dishes like raw cookie dough, homemade aioli, or eggnog.

Preventing Worms from Chicken Eggs

The best way to prevent getting worms from chicken eggs is to follow proper handling and cooking techniques. Here are a few tips to keep in mind:

  • Wash your hands frequently: Before handling any food, including eggs, make sure to wash your hands thoroughly with soap and warm water. This will help prevent any contamination from transferring to the eggs.
  • Clean the egg shells: Before cracking any eggs, make sure to clean the shells with warm soapy water to remove any potential contamination.
  • Store eggs properly: Eggs should be stored in the refrigerator at or below 40°F (4°C) to prevent any potential bacteria growth.
  • Cook eggs thoroughly: Cooking eggs thoroughly is the best way to kill any potential worms or bacteria. Make sure to cook eggs until the whites are firm and the yolks are no longer runny.

Cooking Techniques to Minimize the Risk of Worms from Chicken Eggs

Now that you know how worms can potentially be transmitted through chicken eggs, here are some cooking techniques to help minimize the risk:

  • Hard-boiled eggs: Hard-boiling eggs is a great way to cook them thoroughly. Make sure to boil them for at least 12-15 minutes to kill any potential worms or bacteria.
  • Baking: Baking eggs in dishes like quiches or frittatas is another great way to ensure they are cooked thoroughly.
  • Frying: Frying eggs is a common way to cook them, but make sure the yolk is fully cooked and not runny before consuming.

If you want to consume eggs in raw forms like in smoothies or salad dressings, make sure to use pasteurized eggs. These are eggs that have been heated to a specific temperature to kill any potential bacteria or worms. They can be found in most supermarkets and are a safer option for consuming raw eggs.


In conclusion, while there is a risk of getting worms from chicken eggs, following proper handling and cooking techniques can greatly reduce that risk. Always make sure to wash your hands, clean egg shells, and cook eggs thoroughly. It’s also important to buy eggs from a reputable source and avoid consuming raw eggs unless they have been pasteurized. By taking these precautions, you can safely enjoy the many benefits of chicken eggs without worrying about contracting any worms or bacteria.

In conclusion, while it is possible for humans to contract worms from chicken eggs, the risk can be greatly reduced by following proper handling and cooking techniques. This includes washing eggs before cracking, avoiding raw or undercooked eggs, and cooking eggs until they reach an internal temperature of 160°F. By taking these precautions, you can continue to enjoy the many benefits of chicken eggs without worrying about harmful worms. Remember to always prioritize food safety and follow hygiene practices when handling and consuming eggs. Stay informed and enjoy your eggs responsibly.
