We don’t know what causes most miscarriages, birth defects, and
other reproductive problems. If you work with pesticides and have a
miscarriage or baby with a birth defect, we often can’t tell if it was
caused by exposure to pesticides or if it was caused by something else.
We don’t know what levels of exposure to pesticides are safe for
pregnancy and breastfeeding. Try to reduce or eliminate your exposure as
much as possible during pregnancy and breastfeeding.
