• English breakfasts and traditional Christmas dinners could be off the menu as avian flu prompts fears of egg and turkey shortages.
• The U.K. is currently experiencing its worst outbreak of the highly infectious disease.

LONDON — The classic English fry-up and traditional Christmas turkey dinner could be under threat as Britain deals with the impact of rising cases of avian flu.

Fried, poached, scrambled and boiled eggs may well be off the menu as some British supermarkets have warned that supplies could be disrupted, while grocery stores have also made moves to bolster turkey stocks ahead of the festive season.

Britain's second-largest supermarket group Sainsbury's says it has ordered more turkeys to give itself a "buffer" as the festive season approaches, while the top supermarket chain, Tesco, said in October it expects to have enough turkeys for Christmas, according to Reuters.

Shoppers at discount store Lidl are reportedly only able to purchase up to three boxes of eggs, while the U.K.'s third-largest supermarket chain Asda has limited customers to two boxes per transaction.

The current avian flu outbreak is the largest ever experienced in the U.K., and the government ordered for all poultry and captive birds in England to be kept indoors from Nov. 7 to try to contain the highly infectious disease.

Governments across Europe have culled bird populations to limit the spread of avian flu. Almost six million birds have been killed in the Netherlands since October 2021, while Spain, Bulgaria, Denmark and France have also been badly affected. 

Nearly 50 million birds have been killed in Europe this year as countries try to contain the disease, according to the EU's Food Safety Agency.

The U.S. is also feeling the effects of surging bird flu cases and turkey prices have shot up 73% compared to last year in the run up to Thanksgiving.

Avian flu is believed to have caused the death of more than 410 million birds since 2003, when it was first detected outside of China.
