The Stop & Shop Supermarket Co. LLC said Wednesday that more than $29 million was donated in 2012 through customer, vendor, and associate donations to community organizations in areas where the Quincy-based chain has stores.

Noting that its charitable mission focuses on fighting hunger and promoting healthy communities, Stop & Shop said that $14 million of that total went toward supporting local hunger relief agencies.

Looking ahead, Stop & Shop announced a new three-year commitment to distribute $6 million in ‘‘Fighting Child Hunger’’ grants through its Our Family Foundation.
