Aniline Yellow was involved in the 1981 Spanish ] (TOS). A Madrid-based company imported ] ], dyed by aniline yellow to mark it as unsuitable for human consumption, to be used as a fuel in ]s. However, the company distilled the oil to remove the dye, and sold it as a much more valuable ] for cooking. The result was a rash of ]-type illnesses, with a second stage with ]s, weight loss, ], and muscle wasting. The net result was over 20,000 sick and 400 dead. The chemistry of the poisonous reaction is still subject of a debate.<ref>http://www.researchinformation.co.uk/fse/fse0301/0301issue.php</ref>
<!-- so what, irrelevant to this topic==Toxic oil syndrome==
Aniline Yellow was initially implicated in the 1981 Spanish ] (TOS), although further study suggested the cause was likely contaminated tomatoes.<ref>{{Cite web|url=https://www.theguardian.com/education/2001/aug/25/research.highereducation|title = The Spanish cooking oil scandal|website = ]|date = 24 August 2001}}</ref>

The initial theory of the incident proposed that a Madrid-based company imported ] ], dyed by aniline yellow to mark it as unsuitable for human consumption, to be used as a fuel in ]s. At the time, rapeseed oil was not legal for import for cooking use in Spain. However, the company (or smaller merchants) was accused of distilling the oil to remove the dye and selling it to households, possibly as much more valuable ] for cooking. Patients presented with a rash of ]-type illnesses, with a second stage with ]s, weight loss, ], and muscle wasting. The net result was over 20,000 sick and 400 dead. The chemistry of the poisonous reaction is still subject of debate; later forensic evidence suggests that ] from locally-grown vegetables may be a more likely cause of the symptoms.<ref>{{cite web|url=http://www.researchinformation.co.uk/fse/fse0301/0301issue.php |title=FSE Editorial |access-date=2006-02-02 |url-status=dead |archive-url=https://web.archive.org/web/20070312035802/http://www.researchinformation.co.uk/fse/fse0301/0301issue.php |archive-date=2007-03-12 }}</ref><ref>{{cite web |last1=Woffinden |first1=Bob |title=Cover-up |url=https://www.theguardian.com/education/2001/aug/25/research.highereducation |website=The Guardian |access-date=28 March 2023 |date=24 August 2001}}</ref>-->
