Food and beverage manufacturer Kraft Heinz says it's no longer serving the Lunchables meals it created for U.S. schools.

Issues impacting the Lunchables business include negative publicity that has affected consumer perception of the brand, increased competition and a supply chain issue involving an ingredient supplier’s inability to deliver an ingredient for one of the brand’s most important stock-keeping units.

Kraft Heinz pulled Lunchables from the National School Lunch Program months after a Consumer Reports found the meals had concerning levels of lead ands sodium.
