According to this
article Armadillos eat slugs and can transmit leprosy to humans. From the link:
"According to the
Centers for Disease Control an Prevention, the small, shelled slug eaters are carriers of leprosy. Research published in 2011 in the
New England Journal of Medicine confirmed that armadillos were the only animals known to share the same strain of the disease as humans, and were believed to be the primary culprits behind new transmissions in the Southeastern United States
over the past few years.
While the armadillo-to-human transmission risk is usually low, people can get the disease from eating under-cooked armadillo meat (yes that is a
thing), or coming into contact with blood or feces."
I am not an expert of slugs or leprosy. This
CDC article says:
"Recently, CDC’s
Division of Parasitic Diseases (DPD) was contacted by the
Hawaii Department of Health (HI DOH) for advice regarding three cases of presumed
Angiostrongylus cantonensis (AC) infection. AC, commonly called the rat lungworm, is a parasitic worm and the most common infectious cause of eosinophilic (a type of white cell)
meningitis in humans worldwide. AC has an interesting life cycle. Infected rodents carry the adult worm and pass immature worms in their feces. Mollusks (i.e., snails, slugs, or semi-slugs) become infected by ingesting immature worms in the rat feces. Humans become infected by ingesting raw or undercooked mollusks (these guys can be tiny enough to hide on a nickel; –
check it out! infected with the worms or contaminated raw produce. Transmission might also occur through ingestion of raw or undercooked freshwater shrimps/prawns, crabs or frogs. In humans, AC causes eosinophilic meningitis, the symptoms of which can include headache, stiff neck, nausea, vomiting, low-grade fever, fatigue, and abnormal skin sensations (e.g., tingling or pain). In most cases, the symptoms disappear in weeks to months and most patients recover completely, although rare cases of blindness, paralysis, and death have been reported."
The lesson (to me) is cook your banana slugs well. This
chart surprisingly does not list the safe cooking temperature of slugs, a sad oversight.
