WESTON, Fla. -

The custodial staff will be back at Manatee Bay Elementary to clean up the school after dozens of students were sickened with the norovirus.

The Florida Department of Health said a thorough cleaning of the school eliminated the virus, but cleaning will continue this weekend as a precaution.

Parents blamed the cafeteria as the source of the outbreak, where students said they have been pouring water from a jug instead of drinking bottled water.

The cafeteria will be serving food again on Monday.
