5. Actual results
- Results
Benefits associated with 1-2 up to 3-4 servings per week (3-4 for adult CHD); in some countries toddlers and children aged 3-10 reached the MeHg TWI; high-mercury species named: swordfish, pike, tuna, hake; advice: Member States consider national patterns; toddlers, children and women of childbearing age increase consumption of species low in methylmercury; women of childbearing age should not exceed the TWI.
- Absolute risks
not reported
- Authors' conclusion
National assessment of fish consumption patterns recommended.
