SEATTLE (AP) — A Chipotle Mexican Grill in Seattle has been closed by health officials for repeated food safety violations.

Public Health-Seattle and King County said in a news release Thursday it closed the restaurant in the South Lake Union neighborhood for violations on three different visits. An inspection report shows the violations stem from failing to keep ingredients hot enough, which officials say can contribute to foodborne illness.

Chipotle spokesman Chris Arnold told The Associated Press in an email they are looking into the cause of the violation and will address it.

Officials have been closely monitoring Chipotle restaurants since October when 43 stores in Washington and Oregon voluntarily closed after they were linked to an E. coli outbreak.
