California farm company identified as possible cyclosporiasis outbreak source: Reports

[Cirsium]

32. OK

We sometimes urinate in the field, which is harmless, but defecation is pretty rare and is very unlikely to cause outbreaks like this. We haul porta-potties out into the field when "bathrooms might be miles away" and the hours are long. I just saw a harvest crew go by here yesterday with porta-potties on one of the flatbeds.

Contaminated water is always the most likely culprit on the spread of disease. Water contaminated by sewage or manure is a risk factor vastly greater then if every worker defecated in the field every day. Hikers and campers are a far bigger problem with that than farm workers ever could be.
