(AP) — Twelve day care centers have lost their state operating licenses because of safety concerns, the state Department of Social Services announced Tuesday, as it wrapped up a new round of inspections.The department began inspections in September of all state-licensed day care centers around Louisiana that had previously revoked licenses or recorded deficiencies.DSS Secretary Kristy Nichols said the 12 centers that lost their licenses didn’t correct past violations and posed “a serious threat to the safety of the children.””Because they were repeat-offenders that failed to take corrective action after being cited for serious violations, it was imperative that these centers be closed,” Nichols said in a statement. The centers won’t be able to reapply for a new license for two years.
