Mmmm, parasites. Who wants to hear about roundworms, tapeworms, and other tiny critters that live in your food and water? In some cases, parasites can actually be beneficial, keeping insects from devouring crops and diseases from spreading. But you still don't want them in your food—or anywhere near your house—and based on recent reports to the Centers for Disease Control and Prevention (CDC), intestinal parasites in humans could be on the rise, thanks to climate change, increased international travel, and a number of other factors. In the past few years, scientists have been outlining an unusual rise in parasitic infections that live in everything from drinking water to the ironically named kissing bug to salmon raised in Latin America.
Before you give up your outdoor hikes or your sushi, however, keep in mind that there are other, more damaging parasites you need to be worried about.
