A survey commissioned by Maine Food Strategy found that interest in local food is strong in Maine, but farmers and fisherman can do more to market their products to consumers, who still overwhelmingly shop at large chain grocery stores. Nearly 3 in 5 households spend more than $50 on local food each week, citing freshness, flavor and nutrition. But respondents also said they didn't have enough access to local food and that shopping local could be inconvenient. Fifteen percent said they were part of a community supported agriculture or fishery program in which they pay up front for a share of the season's harvest.
