With the confirmation of the outbreak of A (H5N1), also known as the bird flu virus, in local fowls in ward 6 of Koshi Rural Municipality in Sunsari district, veterinary authorities have stepped up surveillance measures.

The average cost of a dozen large Grade A eggs was $4.95 for customers last month, beating the last record set in 2023 by 13 cents. For retailers, wholesale egg prices also reached an all-time high in February at $7.86, according to economic data platform Trading Economics.

The U.S.'s biggest egg marketplace doesn’t own hens, farms or processing plants. Instead, the Egg Clearinghouse connects large-volume buyers with sellers, providing a crucial service as the deadliest-ever avian-flu outbreak limits supplies.
