Eggs are being imported to meet demand because of a shortfall of 1.5 million eggs a day due to an outbreak of avian flu in Ireland.
One supplier has warned it could take a year before production levels recover.
Supermarkets, which are already experiencing increased demand for eggs during the coronavirus lockdown, have said they are experiencing some “supply issues”.
However, the Irish Egg Association, which represents the main egg-packing companies in Ireland, last night revealed to the Irish Independent that eggs are now being imported to meet the shortfall.
It said the drop in egg production is estimated to be between 10pc and 15pc, although it could be even higher as “this is an evolving situation”.
One supplier has said there is now a daily shortfall of 1.5 million Irish eggs.
An outbreak of avian flu in Co Monaghan last month has seen poultry farmers cull thousands of hens in recent weeks in a bid to bring it under control.
Up to 20pc of the entire laying hen population has been culled, with farmers saying their livelihoods are under threat as a result.
A supplier in the west of Ireland, Pearse Piggott, said the problem could take up to a year to resolve.
"Ireland is 1.5 million eggs short per day due to avian flu.
"It is a low pathogenic non-notifiable disease which means you don't have to notify the public just the Department of Agriculture and your vets," he explained.
"The industry as a whole has made the decision to de-populate the birds, to kill the birds.
"There is no compensation from the Department of Agriculture, the Government or from any fund. There is no insurance.
"The farmer who owns the birds is at the entire loss in terms of costs.
"When your farm goes down with avian flu you go into complete lockdown, then you have to pay to cull and render the birds, which is a massive expense.
"This shortage will be here until Easter next year because all the birds needed to meet demand haven't been born or matured yet.
"It's a nightmare and it's not going to change overnight.
"The problem facing farmers is, do you invest in another 30,000 birds, which cost you €5 a bird, and then have the same problem in three months' time? As a consequence, we have no choice but to increase the price."
While avian flu does not kill the birds it causes them to stop laying or produce small, inferior eggs.
A spokesperson for Musgrave Group, which owns SuperValu, Centra and Mace, said in some instances the full range may not be available as consumer demand has also increased over the past month.
A Tesco Ireland spokesperson said it is "seeing some level of impact on the supply of commercial eggs as a result of avian flu".
It said its supplier has increased the availability of free-range eggs.
Lidl said it had experienced "brief egg supply issues recently" due to the increased demand for eggs coinciding with reported cases of avian flu.
Robert Malone, IFA poultry chairman, confirmed that around 20pc of the country's laying hens had been culled in recent weeks due to avian flu.
"It is recommended that farmers leave the sheds empty for at least three months after an outbreak of the flu, so the shed is cleared, disinfected and left idle, so no production can take place."
Irish Egg Association chief executive Aoife Mac Eoin said there has been an outbreak of "low pathogenic avian influenza of the H6N1 subtype in commercial poultry flocks".
"It is concentrated in Co Monaghan which is the main source of egg supplies in the Republic of Ireland. Movement restrictions have been imposed as a precautionary measure on a number of sites, at various stages since the problem first arose, in order to protect other flocks.
"As a result of this loss of production, at a time of peak consumer demand in the last six weeks, a shortfall in supplies has emerged which has had to be filled by eggs from outside the state.
"The drop in egg production is estimated to be of the order of between 10pc and 15pc, although it may be higher, while demand increased by reported figures of over 30pc."
