More or less true; however, it depends upon the amount and should still be
respected.
"However, while boric acid has become one of the chemicals of choice for
many urban pest control programs, it can be toxic. EPA considers boric acid
as a moderately acutely toxic due to acute effects including oral and dermal
toxicity, and eye and skin irritation. EPA�s reregistration document states
that a subchronic borax feeding study using dogs resulted in blood and
metabolism disorders as well as effects to the testes, endocrine system,
brain weight, and size ratios among various organs and glands. In chronic
oncogenicity studies using mice, rats and beagle dogs, boric acid and borax
were found not to be carcinogenic; however, testicular effects and decreases
in body weight resulted at high dose levels. EPA has classified boric acid
as a �Group E� carcinogen, indicating that it shows �evidence of
noncarcinogenicity� for humans. In reproductive and developmental toxicity
studies using rats, mice and rabbits, maternal liver and kidney effects and
decreased weight gain as well as decreased fetal body weights were observed.
In two studies, at the highest dose levels, no litters were produced.
Prenatal mortality occurred at the highest dose levels in the rabbit study.
Boric acid does not cause mutagenicity (U.S. EPA 1993).
Applicators and others in treatment areas may be exposed to boric acid and
its sodium salts during or after application. However, there is no
reasonable expectation that these pesticide uses may constitute a hazard or
risk to people involved in, or near to, handling or application activities.
Proper care and adhering to label directions and precautions should reduce
exposure and any associated risk (U.S. EPA 1993). "
