Even a single bite can be harmful: Here's how to protect yourself from foodborne parasites.

When should you see a doctor?

See a doctor if you notice the following:

• Persistent diarrhea, vomiting, or abdominal cramps

• Unexplained weight loss

• Fatigue, fever, or signs of anemia

• Visible worms or segments in the stool

Diagnosis   often requires stool or blood tests. Some parasites can cause chronic problems if left untreated.

Travelogue

In many regions with limited sanitation, special caution is advised:

• Eat only   hot, fully cooked food.

• Avoid salads and peeled fruit  from street vendors.

• Drink   sealed bottled water

• Use   alcohol-based hand sanitizer   if soap is not available.

Last memory

While even a single bite of contaminated food can cause an infection, most foods are safe if   prepared properly  . You don't have to give up your favorite foods – just handle them with care. When in doubt:   cook, wash, peel, or avoid altogether.

Stay well informed, handle food carefully, and enjoy your meals without worry.
