A case of a woman finding a dead mouse in her salad at Katie's Pizzeria seems to be an isolated incident.

According to the report from the St. Louis County Health Department, the popular pizza place was inspected on Feb. 13 and received a Grade A (100). According to the complaint:

A customer contacted the Health Department to report that she found a dead mouse in her salad. The manager on duty at Katie's said they took the bag of lettuce back to Restaurant Depot; the Restaurant Depot owner took fault. The restaurant receives pest control services on a monthly basis, according to the report. No other violations were found during the visit. Tim Holland, a manager at Katie's, confirmed the report to Patch. He said staff went to Restaurant Depot after realizing the lettuce in the salad came straight from a package.

"They fully admitted to it and agreed to look through the rest of their shipment," Holland said. A manager at Restaurant Depot who did not want to be identified said the issue was with a supplier.

"They took care of this on the corporate end after I called," she said. "We no longer use that supplier."

Holland added that Katie's has undergone training with staff to ensure that there is closer inspection when opening packaged foods.
