Gardai say they have investigated rumours that Keelings Fruits staff were breaching covid-19 restrictions on movement.
The 189 workers were flown here on a charter flight from Sofia on Monday.
Keelings Fruits says that all of them had been health screened by a doctor before they travelled to the airport and were temperature checked before getting on the Ryanair plane.
Both the airline and Dublin Airport have confirmed that all regulations were adhered to.
The company says they were taken straight to their housing and their movements are being restricted.
However, Gardai say they are aware of social media speculation and received a number of telephone calls about a group of foreign nationals who have recently entered this country to work.
Concerns were expressed that these people were not complying with the COVID regulations.
They have investigated these concerns and no breaches of the COVID regulations have been identified.
The workers will be subject to further medical screening before beginning work at fruit company's North Dublin farm.
