Editing Mars bar (section)

== Animal products controversy ==
In May 2007, Mars UK announced that Mars bars, along with many of their other products such as [[Snickers]], [[Maltesers]], [[Galaxy Minstrels|Minstrels]] and [[Twix]] would no longer be suitable for vegetarians because of the introduction of [[rennet]], a chemical sourced from calves' stomachs used in the production of [[whey]].<ref>{{cite news|url=http://news.bbc.co.uk/2/hi/business/6653175.stm|title=Mars starts using animal products|work=news.bbc.co.uk|publisher=BBC News website}}</ref> [[Rabbi]]nical authorities declared that the products remained [[kosher]] for Jewish consumption.<ref>{{cite web|url=http://www.theus.org.uk/jewish_living/file/?file_id=184 |title=LBD Kashrut Division&nbsp;— It's Kosher anyWhey! |work=theus.org.uk |url-status=dead |archive-url=https://web.archive.org/web/20120406120947/http://www.theus.org.uk/jewish_living/file/?file_id=184 |archive-date=6 April 2012  }}</ref>

The decision was condemned by several groups, with the [[Vegetarian Society]] stating that "at a time when more and more consumers are concerned about the provenance of their food, Mars' decision to use non-vegetarian whey is a backward step".

Mars later abandoned these plans, stating that it became "very clear, very quickly" that it had made a mistake.<ref>{{cite news| url=http://news.bbc.co.uk/1/hi/uk/6673549.stm| work=BBC News| title=Mars bars get veggie status back| date=20 May 2007}}</ref>
