The conditions are very unsafe. Commercial farming has terrible air quality. Farmers have significantly higher rates of cancers including lung cancer. There is no one inspecting workplace conditions when you are hiring undocumented workers. Every bad heatwave in the southwest you hear sad stories of people in fields dying of heat exhaustion because their supervisors provide no shade for breaks or water stations. There are no standards federally even for what might be sufficient despite the massive rates of heat related deaths experienced by farm workers relative to the general population.
