Contact dermatitis from animal feed additives

Occupational dermatitis in animal feed mill workers

“…We wish to stress the presence of allergic contact dermatitis (to our knowledge hitherto unreported in the literature) to the following substances: . On the other hand, various publications report allergic contact dermatitis to the antimicrobial agents we tested, including tylosin and spiramycin (6,7), nitrofurazone (8,9), neomycin (10, 11) and bacitracin (12). Contact allergy to the antioxidants and the colourings we tested have been reported elsewhere (13)(14)(15)(16).…”

Old But Not Gone: Nitrofurazone‐Induced Occupational Allergic Contact Dermatitis in a Racehorse Groom

“…Nitrofurazone is a potent contact sensitiser capable of inducing severe ACD. Occupational cases have been described in individuals exposed during animal care or handling of nitrofurazone-containing animal feed [2,3,6]. Sensitisation to other nitrofuran derivatives, including furazolidone, furaltadone, and nitrofurantoin, further highlights the allergenic potential of this group [8,9].…”

“…Owing to its strong sensitizing properties, it remains a relevant cause of allergic contact dermatitis (ACD) in Turkey [1]. Human cases of ACD secondary to veterinary exposure have been reported [2][3][4][5][6]. Herein, we describe a rare case of occupational ACD in a racehorse groom caused by exposure to nitrofurazone applied to horses.…”

Contact dermatitis to ethoxyquin in animal feeds

“…The handling of animal feed by workers in the industry and by farmers distributing the feed to animals can result in contact sensitivity to various components, such as cobalt sulfate (Breuckner & Hofs 1966), furazolidine (Scharfenberg 1967), ethoxyquin (Melhorn & Beetz, Schubert et al 1973, Burrows 1975, "a pphenetidine-containing anti-oxidant", probably ethoxyquin (Pambor 1971), tylosin (Neldner 1972), quindoxin (Scott & Dawson 1974), and halquinol (Burrows 1975).…”
