Yes, this would apply to Crypto.  Although desiccation will kill oocysts.

There have been reports of crypto on salad crops irrigated with reused 

Reused water in Australia is being treated with 5 ppm chlorine to 
inactivate pathogens.  This does not inactivate oocysts but it does make 
them undetectable.  The chlorine removes the antigen recognised by the Abs
used for detection.

A bit of a worry.
