THE US has banned Vegemite, even to the point of searching Australians for jars of the spread when they enter the country.... or maybe not
... Vegemite has been deemed illegal under US food laws. [It] contains folate, which ... America allows to be added only to breads and cereals.
Vegemite Ban on Snopes
"There is no ban on Vegemite," US Food and Drug Administration (FDA) spokesman Mike Herndon said. Under US regulations, folate can be added only to breads and cereals.
"One of the Vitamin B components (in Vegemite) is folate," Mr. Herndon said.
"In and of itself, it's not a violation. If they're adding folate to it, boosting it up, technically it would be a violation.
"But the FDA has not targeted it and I don't think we intend to target Vegemite simply because of that."
