Several groups of farmworkers and organizations, which represent farmworkers across the United States, have consistently spoken out against the pesticides due to their claims of negative effects on the workers who are exposed to the chemicals. Such groups include Farmworker Justice, El Comité de Apoyo a Los Trabajadores Agrícolas (CATA), and the Farmworker Advocacy Network. While other strictly environmental justice groups have achieved success in reaching their goals by lobbying for regulations and public protests, farmworkers have struggled to advance via similar methods on the issue of workplace pesticide exposure. Groups which focus on pesticides today have opted to use a variety of methods in trying to help those affected by the use of harmful chemicals. Some organizations such as CATA have used pesticide safety training, including tips on clothing to wear. Other groups, such as Farmworker Justice, have called for increased protections by the Environmental Protection Agency and the requirement of reporting pesticide use on a national level, in addition to calling for extensive research on the long-term effects of pesticide use and pesticide exposure on agricultural workers.
