Editing Guar gum (section)

=== Dioxin contamination ===
In July 2007, the European Commission issued a health warning to its member states after high levels of [[Dioxins and dioxin-like compounds|dioxins]] were detected in guar gum, which was used as a thickener in small quantities in meat, dairy, dessert and delicatessen products. The source was traced to guar gum from India that was contaminated with [[pentachlorophenol]] (PCP), a pesticide no longer in use.<ref>{{cite web| url=http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2010:080:0028:01:EN:HTML| archive-url=https://archive.today/20130213053654/http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2010:080:0028:01:EN:HTML| url-status=dead| archive-date=13 February 2013|date=25 March 2010|title=Commission Regulation (EU) No 258/2010|access-date=14 July 2012}}</ref> PCP contains dioxins, which damage the human immune system.<ref>{{cite web| url =https://www.who.int/mediacentre/factsheets/fs225/en/ | title=Dioxins and their effects on human health
