Problem: By the 1950s, with the increase in processed foods, these pesticides began to be concentrated, and a new law to protect Americans from the dangers of consuming pesticide residues was needed. Which of the following were included in the 1958 amendment? All pesticides have to be tested before they can be used to ensure that they are safe for human consumption. Legacy pesticides were grandfathered in without testing and given the classification of "generally regarded as safe" (GRAS). All pesticides were banned from foods as most bioaccumulate and lead to debilitating health consequences, such as cancer. Pesticides classified as GRAS are not required to be tested unless research indicates that they are in fact harmful to human health. Need Assignment Help?
