cyclosporiasis

I was reading that cyclosporiasis  is most likely on veggies like lettuce from Mexico that Taco Bell used for a while in the Michigan and surrounding areas. 

However, I don't fully believe this because it also shows up in water supplies all over the U.S. from about August to September or earlier every year. As water sources become less during the summers combined with increasing heat in summers I believe it causes (the combination of events) for these protozoa to grow in water sources as there is less water in municipal water facilities that time of the year. 

Since Clorine and Fluoride don't kill  cyclosporiasis  it is a good idea therefore to have a reverse osmosis tippet in you kitchen to filter out such protozoa especially if you live in a place where your water comes from municipal water sources in Suburbia or big cities. And even in the country Giardia often gets into wells through deer or cattle feces so having reverse osmosis even there might be useful and prevent people with compromised immune systems like HIV or AIDS patients and older people from dying from cyclosporiasis.
