Are they using Fenitrothion? You might need to get this checked out
All I could find is the Australian version of the MSDS. Got to love MSDS's, they have to list everything upfront, no game playing.
Fenitrothion MSDS (Australia)
signs and symtoms associated with mild exposures to organophosphate and carbamate pesticides inclue: headache, fatigue, dizziness, loss of appetite
with nausea, stomach cramps and diarrhoea; blurred vision associated with excessive tearing: contracted pupils of the eye...
It goes on from there. Says the signs and symptoms can be mistaken for the flu.
I hope it is nothing and just a bit of the flu.
I hope everyone feels better really soon.
BTW, I had to hand copy the MSDS. I couldn't cut and paste. Please forgive me if there are some minor errors.
