HOUSTON -- A city inspector agreed with Houston Independent School District inspectors that a northeast Houston middle school does not have dangerous or unusual levels of mold, KPRC Local 2 reported Monday.

The union representing maintenance and custodial workers in HISD is demanding administrators close parts of Francis Scott Key Middle School. The group claimed in just the past week alone, several people at the school have become sick.

However, the school will be open as planned Tuesday morning.

The question was -- did mold make people sick?

The janitors' union said yes, while Houston Independent School District officials said no, it was bleach that made the janitors sick.

The marches and hubbub over mold at Key Middle School was much ado about nothing, according to one expert.

"I've been involved in similar incidents at other middle schools in other parts of the country, and I would have no problem having my own children here tomorrow," said Robert Gilmore with the ICU Environmental Health and Safety Co.

The pictures of mold at the school are old and are history, according to district officials.

"It's time to stop the scare tactics and stop trying to scare kids. This building's fine," HISD spokesman Terry Abbott said.

KPRC Local 2 did not spot any mold during a guided tour of the school on Monday afternoon.

But that may not be convincing enough for some parents who have not made up their minds if their children will return to school at Key on Tuesday.

"I don't know. I can't say for sure (if my child will attend)," said Sharlene Horace, a student's mother.

Horace said there has been too much conflicting information.

Two city council members joined the fray. They said they were worried about seven janitors who fell ill over the weekend.

"Any kind of mold that is here, I certainly want to find out what it is. And until we know what it is, the school definitely needs to be closed," said Jarvis Johnson, a Houston city councilman.

Eddie Cabrera's wife was one of the sickened janitors.

"It gets you nervous, upset -- what you can't see. You don't know how she's going to react five or 10 years later or maybe next week," he said.

"We don't need to wait until someone dies coming out of that building. We need to have it inspected," said Gayle Fallon, president of the Houston Federation of Teachers.

A city inspector checked the building on Monday.

The city's Health Department said the inspector agreed with the findings of HISD's hired inspectors. There does not appear to be a safety issue related to mold at Key Middle School.
