As It Was: Chicken Cholera Plagues Early Settlers
Cholera plagued early Southern Oregon settlers from the mid to late 1800s. Caused by drinking water or food contaminated by the feces of an infected person, the dreaded disease attacked miners and others who emigrated to the West in search of gold or a new life.
It is said that Chinese mine workers largely avoided cholera because they boiled the water they used for making tea.
Chicken cholera was also virulent and could kill a whole flock. An early remedy for chicken cholera in Southern Oregon was found on an old, handwritten scrap of paper among the archives of the Southern Oregon Historical Society. It called for dissolving iron sulfate in a gallon of boiling water, adding sulfuric acid, and placing the mixture in a tightly corked jug. An addendum to the scribbled note warned the remedy was “certain death for pigs.”
Chicken cholera was one of the first diseases studied by the French chemist and microbiologist Louis Pasteur, who in 1879 created a chicken cholera vaccine, heralding the birth of immunology and a reliable way to save the flock.
