Countries: Philippines, Indonesia, Bangladesh, and India

Higher beta carotene (Golden Rice):• Current level: ~ 0 ppm• Target level: ~6-8 ppm

= +50 % of the estimated average requirementHigher Iron Rice:• Current level: 2 ppm• Target level: 12-14 ppm

= +30 % of the estimated average requirementHigher Zinc Rice:• Current level: 16 ppm• Target level: 24 ppm

High Zn Rice: Update, Bangladesh

• Submission to Varietal Release Committee for testing in 2013 – last phase of field work underway

o first distribution in 2014• Food intake surveys - DONE

o confirmed rice intake levelso confirmed retention levels

• Bioavailability studyo Confirmed absorption in the 20-25% rangeo To be repeated

• Bioefficacy trial - being planned

Participating organizations

Looking aheadGolden Rice would be introduced in the Philippines by PhilRice and other partners as another approach to fighting vitamin A deficiency if it is proven to: match farmers’ and consumers’ expectations for high

quality rice – breeding and testing be safe – food, feed, and environmental biosafety improve vitamin A status – bioefficacy trial be accessible/affordable, especially for those most in

need - planning for Market launch (IRRI/PhilRice) Program launch (HKI)
