just the other day I posted a
kashrut alert from the KF kashrut organization, the Kashrut of the Federation of Synagogues in the UK, regarding Heinz ketchup for Pesach. The production of this ketchup included kitniyot (itself a debatable topic if this is actually considered kitniyot or not, but leaving that aside...) but was labeled as regular kosher for Pesach. the alert was to let people know it actually contains kitniyot so those who refrain from eating kitniyot on Pesach should be aware.
