Cumulative Organophosphate Risk
Assessment Nears Completion
On June 10, EPA released a revised assessment
of the cumulative risk of organophosphate (OP)
pesticides. The Agency has evaluated over a
thousand OP food tolerances, virtually all of which
are expected to meet the highest, most rigorous
safety standards. The Assistant Administrator for
the Agency stated that the risk assessment
conclusions strongly support a high level of
confidence in the safety of the food supply.
Additionally, issuance of the document meets the
EPA’s legal obligations under the Natural Resources
Defense Council (NRDC) consent decree. The
Agency continued by stating that only two out of the
30 OP pesticides examined, dichlorvos (DDVP) and
dimethoate, were still of concern. Action on these
two compounds could range up to a complete ban.

Since the announcement, activist organizations
have not failed to contribute their opinion of the risk
assessment, especially regarding the 10X safety
factor that the
Food Quality
Protection Act
(FQPA)
proscribes to
protect
children’s
health. During a
technical
briefing on June
18, a scientist
with the New York attorney general’s office stated
that she did not believe that the data set was robust
enough to protect children’s health. Other groups
under this impression included NRDC, Consumers
Union, and Northwest Science and Environmental
Policy Research Center. At a meeting of the
Committee to Advise on Reassessment and
Transition held June 19, the co-director of
Farmworker Justice Fund, Inc., questioned whether
the risk assessment would be able to generate a
representative sample of the population that would
sufficiently protect atypical groups that might be
exposed to higher levels of pesticide, such as
migrant farm worker children, who may eat
exclusively produce being grown/harvested on the
farm. The Agency representative replied that the
risk assessment model takes into account abnormal
eating habits, and that is why those extremes were
not excluded from the database. (Chemical
