- Executive summary:
In a peer reviwed developmental study on the effects of benzoic acid on pregnant rats, benzoic acid at doses of 5, 25, 50, and 500 mg/Kg was administered by stomach tube to groups of 20 pregnant Wistar rats on Gestation Days 6-15. Two negative control groups were maintained: one was treated with water, the other with 0.5% carboxymethylcellulose. A positive control group received either thalidomide or aspirin. Dams were killed on Day 21.
Maternal survival was similar for treated and control groups. The incidence of fetal malformations did not reach statistical significance (Polish Academy of Sciences, 1977).
The incidence of fetal malformations in benzoic acid treated rats did not reach statistical significance.
