  Disinfection. Following an outbreak of hog cholera in a
herd, a thorough cleaning up and disinfection of hog lots

destruction of the hog cholera virus. The carcasses of all
' hogs that have died of hog cholera, together with the excreta
and all litter, bedding and refuse contained about the hog i
lot, pens and houses should be raked up and burned.` Fresh
* air-slaked lime should be abundantly scattered about the hog
