I Thought the White String in My Egg Was Something Dangerous—The Truth Completely Surprised Me

What About Parasites in Eggs?

This is a common fear, and it’s understandable. The idea of eating something that might contain a parasite is genuinely unsettling.

Here’s the good news: eggs are remarkably safe.

The USDA and the FDA strictly regulate commercial eggs in the United States. All commercial eggs are washed, graded, and inspected. Parasites in eggs are extremely rare.

In the extremely unlikely event that a parasite were present, it would be killed by cooking. Eggs should always be cooked until both the white and the yolk are firm—not runny. This kills any potential bacteria and parasites.

The chalaza is not a parasite. It’s not a worm. It’s a structural protein. You can eat it without worry.

A Quick Word on Food Anxiety

I’m going to be honest here.

I have a tendency to overthink food. I see something strange, my brain goes to the worst-case scenario, and I spend twenty minutes spiraling instead of just eating my breakfast. It’s a habit I’m trying to break.

The chalaza is a perfect example. I saw a white string and immediately thought “danger.” I didn’t stop to think about the fact that eggs are one of the most studied, tested, and regulated foods in the world. I didn’t consider that maybe—just maybe—the thing I was looking at had a perfectly normal explanation.

If you’re like me, I want you to know this: most things in your food are not dangerous. Most surprises have a simple, harmless explanation. The chalaza is one of them.
