Vegetarian and vegan symbolism
Multiple symbols have been developed to represent lacto-vegetarianism and veganism. Several are used on food packaging, including voluntary labels such as The Vegan Society trademark or the V-Label (with support of the European Vegetarian Union) as well as the vegetarian and non-vegetarian marks mandated by the Indian government.
