As the bird flu continues to wreak havoc on the U.S. egg supply, U.S. Customs and Border Protection data show there have been significantly more egg products seized at U.S. borders than the number of seizures of the powerful synthetic opioid fentanyl so far in fiscal year 2025.

According to the CBP data, there have been 413 drug seizure events involving fentanyl in fiscal year 2025, with December, January and February all having fewer fentanyl seizures than in those months the year before.

Officials warn that bringing in such products, even though they might be cheaper for individuals, carry potential health risks and could make problems even worse.

"This ongoing bird flu outbreak, the worst on record, serves as a reminder of the role human behaviors, such as transporting birds and avian products, can play in disease transmission. Items like soiled bird cages or used egg carton can spread diseases, including ," a respiratory virus that's often fatal to infected birds.
