A parasite is an organism that lives on or in a host and gets its food from or at the expense of its host. In other words, the parasite uses the resources of the person it’s living inside of, such as the very food that that person eats, in order to survive. Worse, parasites can cause disease in humans.
How does someone become infected with a parasite?
Believe it or not, a relatively high percentage of adults living in the United States may carry parasites. Parasites usually come from consuming contaminated food or water, but people with imbalanced gut bacteria, leaky gut syndrome, or a weakened immune system may be more susceptible. Some can also be spread through the bite of a mosquito or sand fly, or from animals that are infected.
Eating undercooked meat and seafood can transfer harmful organisms, including beef, pork, shellfish and crab. Drinking or bathing in contaminated water is another major cause.
