Inspiration for this work came from two sources. First, the lead author (R.C.S.) has been an active participant in the edible flint collaborative since 2011. In 2011, he and Mayfield (cited below) were both participants in the Access & Education workgroup, which partnered with Raise It Up! Youth Arts and Awareness to conduct a pilot study examining healthy food availability in stores in north Flint (Pleasant et al., 2012). edible flint was founded in 2009, and has the stated goal to ‘support Flint residents in growing and accessing healthy food in order to reconnect with the land and each other’ (http://www.edibleflint.org).
Second, this pilot formed the basis of further work conducted by Mayfield and colleagues (Mayfield, 2016; Mayfield et al., 2013, 2016). Few food access studies had included data on the wide variety, types of foods and food stores that edible flint was interested in learning more about. Mayfield continued to work in partnership with edible flint to deploy the first citywide survey of access to healthy foods, named the Flint Food Store Assessment (FFSA) and based on the NEMS-S and FROST (Hosler and Dharssi, 2011). Our survey is likewise based on the NEMS-S, using the standard scoring system with 5 points added for additional Pb-mitigating food items not on the original survey.
