EFSA: mercury in food (2012)
Scientific Opinion on the risk for public health related to the presence of mercury and methylmercury in food (EFSA press release: 'Mercury in food - EFSA updates advice on risks for public health', 20 December 2012)
Overview
EFSA CONTAM Panel. EFSA J / EFSA press release 2012 · DOI 10.2903/j.efsa.2012.2985
EFSA set a weekly safety limit for methylmercury; tuna, swordfish and pike are among the main sources.
Does the study support the specific claim? No · Methodological quality: high

5. Actual results
- Results
TWI methylmercury 1.3 µg/kg bw (lower than JECFA's 1.6); inorganic mercury 4 µg/kg bw; average exposure unlikely to exceed TWI, but likelihood increases for high and frequent fish consumers, which may include pregnant women; main contributors 'tuna, swordfish, cod, whiting and pike', plus hake for children.
- Absolute risks
not reported
- Authors' conclusion
If risk managers reduce MeHg exposure, beneficial effects of fish should also be considered.
