It might've been stuffed with drugs.
If the bologna was stuffed with drugs they would have gladly said so. Truth is lunch meat and especially homemade cheese is smuggled across the border in large quantities regularly and sold. Every now and then there are cases of food poisoning and listeria traced back to it. Some of the homemade cheeses are made in home bathtubs like gin back in the day. Some of the Mexican cheese is really good but you have to be really careful and know where it came from. Bologna is also caught often, but not usually in large amounts like this bust.
