ATLANTA -- CBS Atlanta News had some tough questions for the director of the Fulton County Environmental Health Department regarding some questionable inspections performed at a dining hall on the Morehouse College campus.

"Was this done so that you could keep the dining hall open during graduation weekend?" asked CBS Atlanta Reporter Adam Murphy. "No," said Fulton County health director Dr. Patrice Harris.

On May 6, Chivers Hall failed a health inspection with 54 points and a U for unsatisfactory. The dining hall received 83 points and a B on a second inspection one week later which was the Friday before graduation. The report from the second inspection said fried tilapia, baked chicken and green beans were at unsafe temperatures. The report also suggested that the cafeteria discard all expired food and aggressively treat the insect and rodent infestation.

So how did the dining hall score a B? What the second inspection failed to mention is that the Health Department only deducted some of the violations on the report. If all of the violations had been deducted, the dining hall would have scored 48 points and another unsatisfactory score.

"So knowing that we were going to be on site to monitor these issues, that is the reason we scored it that way. In fact, this was a temporary score and again it should have been more clearly noted on the report," said Harris.

The actions of the Fulton County Environmental Health Department raised some questions because, according to the state health code, a food service establishment that is graded as a U on two consecutive routine inspections will be asked to voluntarily close until all violations are corrected.

The state health code also states that a food service establishment that is graded as a U and does not earn at least a grade C within ten days of receiving the U will be requested to voluntarily close until all violations are corrected. In this case, Chivers Hall remained open for graduation weekend.

"Was there preferential treatment?" asked Murphy. "Absolutely no preferential treatment. What happened was we were scheduled to go back for a follow up and when our inspectors got out there they realized this is graduation weekend and thousands of people will be served," said Harris.

Harris told CBS Atlanta that the second inspection was considered a special event so the 83 was a temporary score. The Health Department also had inspectors at the school dining hall during graduation weekend checking temperatures on every tray of food. Harris was unable to tell CBS Atlanta the last time they scored a school dining hall inspection this way.
