According to a Department of Homeland Security release, U.S. Customs and Border Protection (CBP) intercepted 221 attempts to introduce prohibited meat products during the first week of 2023 at the Laredo, TX point of entry. High traffic is experienced after the holiday season as vacationers and foreign workers return to the U.S. Over a four day period, pork products were the most commonly encountered contraband predominantly in the form of pork bologna.
As with any form of smuggling, the products interdicted represented only a proportion of the total quantity introduced across the Southern border. Smuggled meat and poultry has the potential to introduce exotic diseases but more of concern to livestock than poultry. 
A more serious problem is the commercial shipment of illegal meat and poultry products in containers with fraudulent manifests. This is especially a risk with importation of illegal specialty oriental items packed in containers with products that are eligible for importation preventing detection at point of entry. The 1999 extensive outbreak of foot and mouth disease in England with extension to France resulted from illegal importation of meat products for an ethnic restaurant in Newcastle-on-Tyne.
