Following two days of disruption last week, classes are expected to resume at the Titchfield High School in Portland Monday January 28.
Classes were suspended on Thursday and Friday following a scare of Mucuna pruriens more commonly known as cowitch' at the institution.
There were reports that pollen from the cowitch plant was released into the air resulting in student in at least 20 classrooms being affected.
Acting Principal of Titchfield High, Richard Thompson, said the Ministry of Health advised that the school should remain closed until Monday to facilitate clean-up operations.
School officials have been speculating that someone deliberately released the cow-itch inside the classrooms.
