According to Bellone, another 48 people associated with the location are self-isolating.
In addition, a second cluster of positive cases in Suffolk County resulted from a gathering of students from the Shoreham Wading River School District.
The 32-person gathering led to three positive cases.
Bellone says 11 staff members and 140 students are under quarantine, in addition to a number of household contact, which brings the total number of people under quarantine to 161.
He says the COVID positivity rate in Suffolk County hasn't been below 1% since Oct. 21, and that over the past week, the county has averaged nearly a 1.5% positivity rate.
