Which of the following ethnic groups is at highest risk in the United States for pesticide-related injuries?

Hispanic people are at the highest risk in the United States for pesticide-related injuries due to their significant representation among migrant workers in agricultural settings. Working in such environments exposes them to pesticides more frequently, thus elevating their risk compared to other ethnic groups. In contrast, Native American, Asian-Pacific, and Norwegian populations are not as commonly engaged in agricultural work involving pesticide exposure, which makes them less susceptible to pesticide-related injuries. Therefore, the correct answer is Hispanic.
