“…This phenomenon was first reported in onion-fed cattle in 1909 (Goldsmith, 1909); hemolysis has subsequently been described in cattle, horses, and sheep fed cull onions (Thorp and Harshfield, 1939; Koger, 1956;Kirk and Bulgin, 1979;Gill and Sergeant, 1981) and in animals fed onioncontaining vegetable waste (Hutchison, 1977) or grazed on pastures containing wild onions (Pierce et al, 1972). Onion-induced hemolysis has also been reported in cats and dogs (Gruhzit, 1931a; Kaiser et al, 1951; Kobayashi, 1981;Harvey and Rackear, 1985;Yamoto and Maede, 1992). Although these animals do not readily accept a diet containing onions, they appear to be particularly vulnerable to the toxic effects of the latter, with a number of clinical cases of hemolytic anemia being recorded in pets fed quite small amounts of these vegetables (Spice, 1976;Stallbaumer, 1981;Kobayashi, 1981; Smith and Ellison, 1986).…”
