According to US border officials, rising egg prices are causing an increase in attempts to smuggle eggs from Mexico. Officers at the San Diego Customs and Border Protection Office have seen an increase in attempts to smuggle eggs, according to a tweet from the director of field operations. Bringing eggs to the US from Mexico is illegal, because of the risk of bird flu and Newcastle disease, a disease that affects birds. The reason egg prices have skyrocketed so much is because there is a big outbreak of avian flu among American chickens, and it is a deadly disease.
