“…The epidemiologic characteristics are similar to those reported in others studies. 7,18,27 It has been shown that mortality rates may be high if onion consumption continues. The macroscopic and histologic lesions suggested a hemolytic-induced disease similar to that reported in spontaneous onion toxicosis in cattle, sheep, and horses.…”

“…Blood transfusion may be given to severely affected animals and may promote clinical recovery. 5,10,22,27 Oral antibiotics treatment may be beneficial in reducing ruminal anaerobic bacteria that promote the formation of some oxidative substances. 22 A possible alternative to the unrestricted ingestion of onions by ruminants might be to crush these plants and mix them with the feed at no greater than 25% of the entire diet.…”

“…1,15 Toxicosis outbreaks in cattle occur mainly where culled cultivated onions are inadvertently fed to livestock or where animals have access to places where onions are stored. 7,10,18,27 Dogs are usually affected by ingestion of homemade food or when onions are used to improve the flavor of diets prepared for ill animals. 3,14 In cats, onion toxicosis can occur after the ingestion of some human baby foods, which are fed to anorexic animals because of higher palatability.…”

Abstract. Toxicosis caused by the ingestion of onion (Allium cepa) by 5 water buffalo (Bubalus bubalis) occurred in the district of Caçador, Santa Catarina, Brazil. The water buffalo died after ingestion of a large quantity of onion that had been left in the pasture. Clinical signs started 8 days postingestion and were characterized by pale mucous membranes, lethargy, and dark urine. At necropsy, pieces of onions were found in the rumen of 1 animal. The carcass smelled strongly of onion, and the kidneys and urine were dark brown. Microscopic renal lesions included tubular degeneration and necrosis with deposits of eosinophilic material in the cytoplasm of renal tubular epithelial cells and tubular lumina. These changes were consistent with hemoglobinuric nephrosis. Centrilobular coagulation necrosis was observed in the liver accompanied by hemorrhage and macrophages containing brown cytoplasmic pigment. A diagnosis of hemolytic anemia caused by onion toxicosis was based on the epidemiological data, clinical signs, macroscopic changes, and histological lesions.
