Investigates whether the acute symptoms reported by farmers less than 24 hours after dipping with organophosphates (OPs) could be plausibly grouped into distinct symptom categories. Re-analysis of the symptom data obtained in the Health and Safety Executive's (HSE's) Contract Research Report 74/1995 was performed in order to identify any recognisable cluster of core symptoms in exposed subjects, and to evaluate if exposed and control subjects differed in their pattern of symptom reporting. The core symptom groups were also analysed alongside a surrogate of exposure data to assess if significant increases in reporting of any core symptoms were dose-related. Concludes tentative support for the view that certain symptoms can be identified which occur more frequently in those recently exposed to OPs within certain clusters and that these symptoms are consistent with flue-like illness, however, further verification is needed.
