Accidentally consumed undercooked eggs?


Hello, Dr.
Chen.
Last night after work, I came home feeling tired and hungry, so I quickly made a bowl of instant noodles and added an egg to it.
The water I used was hot water boiled to 98 degrees Celsius from a regular thermos.
After letting it steep for three minutes, I ate the noodles and even drank all the broth.
However, towards the end, I noticed that some of the egg white was still translucent, indicating that it wasn't fully cooked.
I only realized this after finishing it.
Is there a risk of contracting any infectious diseases like avian influenza or salmonella? I would appreciate your clarification, doctor.

Dr. Chen Shuliang reply Influenza


Consuming eggs that are contaminated with Salmonella and not properly cooked can lead to acute gastroenteritis (symptoms include vomiting, abdominal pain, diarrhea, etc.).
The incubation period is 8-48 hours, and most healthy individuals will experience a self-limiting resolution of symptoms within 3-7 days.
Infection with the avian influenza virus requires a relevant exposure history, and the infection can affect various sites: 1.
Lungs: pneumonia; 2.
Gastrointestinal tract: patients may experience vomiting, diarrhea, and abdominal pain; 3.
Upper respiratory tract: influenza-like symptoms (fever (ear temperature above 38°C), sore throat, cough, muscle aches, headache, and general malaise).
If there are currently no symptoms, there is no need to be overly concerned.
If you experience any discomfort, please visit an infectious disease clinic for evaluation.

More Info


Eating undercooked eggs can raise concerns about food safety, particularly regarding the risk of infections from bacteria such as Salmonella. While the risk of contracting diseases like avian influenza (bird flu) from consuming undercooked eggs is generally low, it is important to understand the potential health implications.

Salmonella is a type of bacteria that can be found in raw or undercooked eggs, and it is one of the most common causes of foodborne illness. Symptoms of Salmonella infection can include diarrhea, fever, abdominal cramps, and vomiting, which typically appear six hours to six days after infection and can last between four to seven days. In severe cases, the infection can lead to hospitalization, especially in vulnerable populations such as young children, the elderly, and individuals with weakened immune systems.

In your case, since you consumed a bowl of instant noodles with an egg that was not fully cooked, there is a possibility that you ingested some Salmonella if it was present in the egg. However, the risk is not absolute. The likelihood of infection depends on several factors, including the overall health of the individual, the presence of bacteria in the egg, and how the egg was handled prior to cooking.
Regarding avian influenza, this virus primarily affects birds, and while it can occasionally infect humans, the transmission typically occurs through direct contact with infected birds or their droppings, rather than through the consumption of eggs. The risk of contracting avian influenza from eating undercooked eggs is considered very low, especially if the eggs come from a reputable source and are handled properly.

To minimize the risk of foodborne illnesses in the future, consider the following safety tips:
1. Cook Eggs Thoroughly: Ensure that eggs are cooked until both the white and yolk are firm. This helps to kill any potential bacteria present in the egg.

2. Use Pasteurized Eggs: If you prefer recipes that require raw or lightly cooked eggs, consider using pasteurized eggs, which have been heat-treated to kill bacteria without cooking the egg.

3. Practice Good Hygiene: Wash your hands, utensils, and surfaces thoroughly after handling raw eggs to prevent cross-contamination.

4. Store Eggs Properly: Keep eggs refrigerated and consume them before their expiration date to reduce the risk of bacterial growth.

5. Be Cautious with High-Risk Groups: If you or someone you are cooking for is in a high-risk group (young children, elderly, pregnant women, or immunocompromised individuals), it is best to avoid undercooked eggs altogether.

In summary, while the immediate risk of contracting a serious illness from consuming undercooked eggs is relatively low, it is advisable to take precautions to ensure food safety. If you experience any symptoms of foodborne illness after consuming undercooked eggs, it is important to seek medical attention. Always prioritize safe food handling practices to protect your health and well-being.
