Live snails, fresh leaves and a quarter-pound of beef were found this month - not on a plate or grocery store but inside luggage at a Texas airport. A passenger arriving from Nigeria initially disclosed the dried beef in her suitcase, before adding 15 giant African land snails to her declaration. The snails, which were handed over to the US Department of Agriculture (USDA), can cause meningitis in humans.
They are illegal to own in the US without a permit. Giant African land snails are among the most damaging snails in the world. They are native to West Africa, where they are considered a delicacy. But they're also known to carry a parasite with a rather menacing name: rat lungworm. This parasite can cause meningitis, an inflammatory illness that affects the brain and spinal cord.
More than 2,800 cases of the disease have been reported across 30 countries, according to the US Centers for Disease Control and Prevention (CDC). The July discovery by Houston border agents is one of an estimated 250 pests found each day at US ports of entry.
