E Coli & Spinach

I read that there have been many problems with E-Coli in produce in the Salinas Valley, in prior

and not so publicized agicultural reports. I think the practices in the Salinas Valley are careless

and irresponsible. If they don't do it right, they do cause the spread of disease, just as with

polluted water. Wouldn't it be true that if you hire 3rd world workers, you will get 3rd world

agricultural practices?
