Sushi in Pregnancy, Parasitic Diseases – Obstetrician Survey

Abstract

Parasites from raw fish can lead to a wide range of clinical manifestations and can be challenging to treat in pregnancy as result of medication exposure of the foetus. We surveyed obstetrician-gynecologists (ob-gyns) in the U.S. to determine their knowledge about the consumption of raw fish during pregnancy. In March 2007, a questionnaire was mailed to members of the American College of Obstetricians and Gynecologists (ACOG) randomly selected to represent all members. Non-responding physicians were sent two additional mailings. Of the 606 ACOG members surveyed, 305 (50%) responded. Most (82%) respondents indicated that eating raw fish is not safe during pregnancy. However, few (19%) knew that thorough freezing kills parasites in fish. Nearly all (94%) respondents thought that parasitic infections can be more challenging to treat in pregnancy. U.S. ob-gyns believe that eating raw fish during pregnancy is not safe; most would benefit from information about how to prevent infection and about treatment.

Consumer Understanding of the Benefits and Risks of Fish Consumption During Pregnancy

“…26 They are also advised to avoid raw fish (such as sushi or sashimi) because it is more likely to contain parasites or bacteria than cooked fish. 27 Some worry about ecological harms from overfishing or pollution from poorly managed farmed fisheries. 28 In a review of the issues surrounding fish consumption, Oken et al 28 found that there were 21 unique major seafood consumption guidelines or advisories from governments (state and national), nonprofit, and other nongovernmental organizations that targeted various North American populations.…”
