			Many foods contain tartrazine in various proportions, depending on the manufacturer or person preparing the food. When in food, tartrazine is typically labelled as "color", "tartrazine", or "E102", depending on the jurisdiction, and the applicable labeling laws (see ] below).
			Products containing tartrazine commonly include processed commercial foods that have an artificial yellow or green color, or that consumers expect to be brown or creamy looking.

			== Regulation ==
	On September 6, 2007, the British ] revised advice on certain artificial food additives, including tartrazine.
			=== North America ===
			==== Canada ====
			Tartrazine is listed as a permitted food coloring in Canada.<ref>, Food and Drug Regulations</ref> The majority of pre-packaged foods are required to list all ingredients, including all food additives such as color; however section B.01.010 (3)(b) of the Regulations provide food manufacturers with the choice of declaring added color(s) by either their common name or simply as "colour".<ref>{{Cite web|last=Branch|first=Legislative Services|date=2022-01-05|title=Consolidated federal laws of canada, Food and Drug Regulations|url=https://laws-lois.justice.gc.ca/eng/regulations/C.R.C.,_c._870/page-13.html|access-date=2022-02-03|website=laws-lois.justice.gc.ca}}</ref>
			The maximum permitted level of tartazine is 300 ].<ref> - Health Canada, 18 December 2024</ref>
	Professor Jim Stevenson from Southampton University, and author of the report, said: "This has been a major study investigating an important area of research. The results suggest that consumption of certain mixtures of artificial food colours and ] preservative are associated with increases in hyperactive behaviour in children.
			==== United States ====
	"However, parents should not think that simply taking these additives out of food will prevent hyperactive disorders. We know that many other influences are at work but this at least is one a child can avoid."
			The United States requires the presence of tartrazine to be declared on food and drug products (21 ] 74.1705 (revised April 2013), 21 ] 201.20) and also color batches to be preapproved by the ] (FDA).<ref name="FDA" /> As part of these regulations, the FDA requires that the Precautions section of prescription drug labels include the warning statement, "This product contains FD&C Yellow No. 5 (tartrazine) which may cause allergic-type reactions (including bronchial asthma) in certain susceptible persons. Although the overall incidence of FD&C Yellow No. 5 (tartrazine) sensitivity in the general population is low, it is frequently seen in patients who also have aspirin hypersensitivity."<ref></ref>
			The FDA regularly seizes products if found to be containing undeclared tartrazine, declared but not FDA-tested, or labeled something other than FD&C yellow 5 or Yellow 5. Such products seized often include noodles.<ref>{{cite web|author=ORA |url=http://www.accessdata.fda.gov/cms_ia/importalert_118.html |title=Import Alert 45-02 |publisher=fda.gov |date=May 2, 2013 |access-date=May 5, 2013}}</ref>
