Earlier quoted context omitted.
These farm workers live in bunk houses basically and are trucked in on school buses. Most of them are migrant laborers or undocumented immigrants. Those conditions are not safe.
There's a big difference between "the job can't be done safely" and "the way the job was done previously wouldn't be safe if they continue doing it that way". There's literally no step in "picking strawberries" that can't be done while maintaining social distancing. It will increase the cost of labor, and force humans to be treated like... humans. But farming isn't inherently unsafe re: coronavirus.
I'm not saying this to justify the current conditions, I'm just pointing out that it's this or an eradication of the industry.
edit: an eradication I'm totally fine with.
