West Africans love meat, and especially bush meat. The all-time favourite in Nigeria is the grasscutter (or giant cane) rat, which is a bit like a spineless porcupine and can weigh as much as 8kg. They can carry a range of parasites, some of which are transmissible to people.
Many, however, are captive-bred for the meat market, and since they are less likely to have been treated with antibiotics than local chickens, they are perhaps a preferable option for those who want culinary adventures.
In fact, in many resource-poor countries there is such profligate and uncontrolled use of antibiotics in animals bred for the table (especially poultry) that it is a public health issue.
In the West there is tight control of the kinds of antibiotics used in animals, as antibiotic-tainted meat is leading to widespread resistance to antibiotics, and thus treatment failures when they are needed to combat infections in humans.
