Two cases of porcine epidemic diarrhea (PED) were recently discovered at farrow-to-finish hog farms in Elgin County.
The first diagnosis was confirmed on Feb. 4 and the second on Feb. 9.
The Ontario Ministry of Agriculture and Food does not release the location of new cases of the outbreak, only the county in which a case is found.
As of Monday, 11 cases of PED had been confirmed in Ontario, Chief Ontario Veterinarian Dr. Greg Douglas said.
The Ontario outbreak of the contagious pig disease was first discovered on a Middlesex County farm on Jan. 22.
