An August 6 Governing article reported that Missouri voters appear to have narrowly adopted a right to farm state constitutional amendment, although a recount is likely.  The article noted that with passage of the  amendment, Missouri will join North Dakota as the only two states with a constitutional right to farm.   From the article:

Supporters, backed by the Missouri Farm Bureau, argued farmers need greater protection from the kinds of food or agricultural regulations that have gained traction in recent years, such as bans on the use of genetically modified seeds, labeling requirements for foods that include genetically modified ingredients, restrictions on dog breeding, setback rules and efforts to address animal treatment in large livestock operations. They freely acknowledged that pushing for those types of laws would be harder if farming were a constitutional right.

Opponents included smaller farmers, animals rights groups, sustainable agriculture organizations and critics of corporate food practices. They noted that Missouri farmers, like those in every other state, already have protection from nuisance complaints.
