A largely rural county in CA, an urban county in TX, and the metropolitan Atlanta area were selected as study sites. Stores selling groceries and snacks in the selected areas were visited and surveyed for\n CM<\/jats:styled-content>\n products. A mobile application was used to record product data, including product identifiers (e.g., brand name, product type) and folic acid information (e.g., presence and amount of folic acid, folic acid graphical design element). Analyses were performed using R studio.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n In the 111 stores surveyed, products identified included 50 distinct retail\n CM<\/jats:styled-content>\n flour bags, 178 distinct corn tortilla products, 88 distinct tostada products, and 223 other distinct\n CM<\/jats:styled-content>\n products. Fifty percent of distinct\n CM<\/jats:styled-content>\n flour bags (25\/50) were fortified with folic acid. Additionally, 1% (2\/178) of tortillas and about 3% (3\/88) of tostadas were fortified. No other fortified products were identified.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Almost a decade after voluntary folic acid fortification of CM flour was allowed, very few ready\u2010made CM products assessed in this study were fortified. As states work to initiate changes to increase the availability of fortified products, continued assessment can help monitor the availability of fortified products for NTD prevention.<\/jats:p>\n
