Which of the following is a method of preventing parasitic infections?

Hand washing is a fundamental method of preventing parasitic infections because it effectively removes pathogens from the hands, thereby reducing the likelihood of transmission. Many parasitic infections are spread through fecal-oral routes, primarily via contaminated food and water or surfaces. By practicing proper hand hygiene, individuals can eliminate parasites and their eggs from their hands, especially after using the restroom, before meal preparation, and before eating.

In contrast, the use of antibiotics is not effective against parasitic infections as they target bacterial infections. Eating raw vegetables, while healthy, may increase the risk of ingesting parasites if those vegetables are contaminated. Drinking untreated water is a high-risk behavior that can lead to a variety of parasitic infections, particularly those caused by waterborne parasites. Thus, hand washing stands out as a crucial preventative measure in the fight against parasitic diseases.
