BACKGROUND		

The EPA is supplying the following incident report to fulfill our
requirement to docket summaries of incident data that were reported to
the Agency, as well as to ensure human incident data are part of the
problem formulation phase of registration review.  Reports of adverse
health effects allegedly due to a specific pesticide exposure (an
“incident”) are largely self-reported and therefore, generally
speaking, neither exposure to a pesticide or reported symptom (or the
connection between the two) is validated.  Typically, causation cannot
be determined based on incident data. However, incident information can
be an important feedback loop to the Agency – incidents of severe
outcome, or a suggested pattern or trend among less severe incidents can
signal the Agency to further investigate a particular chemical or
product.

The OPP Incident Data System (IDS) was consulted for poisoning incident
data on the active ingredient chlorpyrifos methyl. The purpose of the
database search is to screen for potential patterns on the extent and
severity of the health effects attributed to chlorpyrifos methyl
exposure.  The IDS includes reports of alleged human health incidents
from various sources, including mandatory Federal Insecticide, Fungicide
and Rodenticide Act (FIFRA) Section 6 (a) (2) reports from registrants,
other federal and state health and environmental agencies and individual
consumers. Since 1992, OPP compiles these reports in IDS.  Reports
submitted to the IDS represent anecdotal reports or allegations only,
unless otherwise stated in this report.  

The evaluation of incident data for chlorpyrifos methyl has reported 0
incidents occurring in the United States from 2002 to the present for
the single chemical only.  Because there are no incident cases
identified, there does not appear to be a risk concern at this time that
would warrant further investigation.  The Agency will continue to
monitor the incident information and if a concern is triggered,
additional analysis will be included in the risk assessment.
