Pregnant women are urged to avoid fish high in methylmercury (MeHg) since it can limit the fetus’ brain development; however, ﬁsh is a good source of omega-3’s which promote brain development. Agencies issue consumption advisories to inform the public about the risks & benefits of eating ﬁsh; however, the difﬁculty in communicating both the risks & beneﬁts lead readers of the advisory to inappropriately over-restrict their ﬁsh consumption. The authors worked with Maine CDC and UNE personnel to test the effectiveness of Maine’s advisory. Compared to nonreaders, they find the advisory increased women’s: knowledge of both the beneﬁts and risks of consuming ﬁsh while pregnant, ability to differentiate ﬁsh by their MeHg content, and knowledge of specific low and high-MeHg ﬁsh. This suggests the advisory has the potential of reducing MeHg-related health risks while avoiding the drop in ﬁsh consumption show in other studies.
