Purpose/Objectives: This study aimed to describe efforts by Minnesota public School Food Authorities (SFAs) to implement the Smart Snack regulations in secondary schools and challenges associated with implementing these regulations five years after they went into effect. Methods: Public SFAs (n=452) in Minnesota were invited to complete an online survey that included up to 32 questions related to implementation of Smart Snack regulations in their competitive food sales--a la carte, vending machines, fundraisers, school stores/snack carts. Question formats included open-ended, multiple choice, select all that apply, and rating scale response from the following options: "strongly disagree," "disagree," "agree," "strongly agree," "unsure/not applicable." Frequency of responses was calculated for each question with qualitative data analysis methods used to analyze responses to open-ended questions. Results: A total of 247 responses was received (55% response rate). Most participants (95%) indicated they "agree" or "strongly agree" that they felt knowledgeable about the Smart Snack regulations, but over half (53.2%) indicated they "agree" or "strongly agree" that Smart Snacks are difficult to implement in secondary school sites. For all types of competitive food sales, the most frequent action taken in response to the Smart Snack regulations was to replace non-compliant foods with compliant foods. Failure to take action in response to Smart Snack regulations was reported as highest for fundraisers (18.9%) and school stores/snack carts (7.1%). Conclusions: The strategies and challenges identified in this study could be used to create targeted training and education materials to support school districts' efforts to comply with Smart Snack regulations.
