In 2018 Missouri legislators passed the Missouri Meat Advertising Law which bans use of “meat” in the names of products not derived from animals. A federal lawsuit has been filed for injunctive and declaratory relief on grounds of overbreadth and facial unconstitutionality.

In 2016 Vermont congressman Peter Welch and 24 congressmen from dairy farming states requested that the FDA exclude plant-based milks from the definition of “milk.” They also introduced the federal “Dairy Pride Act” which would mandate a ban on labels such as “soy milk”. It did not pass.

In 2014 Unilever sued vegan company Hampton Creek for labeling its plant-based mayonnaise “Just Mayo” because the product did not contain eggs. Mayonnaise contains eggs. Unilever lost.
