A few weeks after City Councilor John Connolly discovered expired frozen food in four Boston Public Schools, outdated food was found in as many as 48 schools and the district’s director of food and nutrition was removed from her post.

During a hearing yesterday, Connolly said double ordering and paying for food — some of which was stored for more than a year — cost taxpayers thousands.

“What I have learned paints a picture of severe mismanagement,” he said.

Superintendent Carol Johnson said $7,000 in questionable food was removed and an additional $107,000 worth is under review.

“Let’s be clear, the food we serve to our students is safe. We are not in denial about the concerns you have raised ... We continue to work aggressively to solve them.”
