Drugs worth over €713,000 have been seized across the Mayo Garda division since the start of this year.
The figure was given by Superintendent Joe McKenna at today's meeting of the Mayo Joint Policing Committee.
He outlined that, in addition to the drugs seized worth €713,586, over €68,000 cash was also discovered during these searches.
54 drug detections have been recorded in Mayo so far this year.
It comes as Gardai have today launched Operation Tara - a national anti-drugs operation, which will tackle street-level dealing in towns, villages and cities across the country.
The focus of the operation is to disrupt, dismantle and prosecute drug trafficking networks at international, national and local levels.
321 Gardai are now assigned fulltime to Divisional Drug Units across the country, and the increase in the size of these units has seen significant amounts of drugs seized and arrests made.
Garda Commissioner Drew Harris says the scourge of drug-dealing "is no longer confined to cities, but is happening in towns and villages around the country, and Operation Tara will tackle that scourge".
Members of the public with information on drug importation and supply are asked to report the information to the Garda Confidential Line 1800 666 111 or Crime Stoppers on 1850 25 00 25.
