In May 1999,the Bundesinstitut fur gesundheitlichen Verbraucher-schutz und
Veterinarmedizin (BgVV) (Federal Institute of consumer health protection an
d veterinary medicine) recommended that pregnant women should nor consume c
ertain species of fish because of neurotoxic effects of methyl mercury on t
he development of the fetal brain. Evaluation of two studies not mentioned
in the BgVV's warning has shown, however, that, from the toxicological poin
t of view, there is no reason to restrict the recommendation by the German
Society for Nutrition advising pregnant women in Central Europe to eat one
to two fish meals per week.
