Stena Line has confirmed it has cancelled all crossings between Fishguard, and Rosslare, until 12 April.
Any passengers who usually travel from Fishguard are being told to book on the service from Pembroke Dock instead.
Stena Line's Simon Palmer explained, "Due to the suspension of P&O's services into Northern Ireland there were supply fears in the region,"
Hauliers in Northern Ireland warned they were running at 50% capacity because of issues, after P&O sacked workers and suspended services at the end of March.
John Martin, from the Road Haulage Association, said there were "two boat-loads of vehicles" sitting in Cairnryan in Scotland waiting for a ferry to Larne, sparking food supply concerns.
