“…8,14 Our results and literature reports suggest that different arsenic compounds may cause different histologic lesions. 1,3,5,8,12,14,17,20 In this episode of LA poisoning, the main lesions were in the forestomachs, thus these toxicants should be considered in the differential diagnosis of ulcerative and necrotizing lesions of these organs. In Uruguay, Argentina, and Brazil, poisoning by Baccharis coridifolia, a toxic plant that contains macrocyclic trichothecenes, causes clinical signs and lesions very similar to those described in LA poisoning, including severe necroulcerative lesions in the forestomachs and lymphoid necrosis.…”

“…These lesions have occasionally been described in ruminants poisoned by LA. Hemorrhages and rumenitis with shedding of the ruminal mucosa have been reported in an outbreak of LA poisoning in cattle, 12 and hemorrhagic erosions of the ruminal wall were reported in sheep poisoned experimentally by LA. 19 However, histologic lesions of the forestomachs were not described in either report.…”

We describe and illustrate lesions in an outbreak of lead arsenate poisoning in beef cattle that ingested pesticide residues stored in an abandoned building of a former orange orchard. Of 70 exposed cattle, 14 had diarrhea, paresis, ataxia, recumbency, and/or seizures. Ten of the affected animals died after a clinical course of 12-18 h. Pathologic findings in 3 steers included extensive necrohemorrhagic, ulcerative rumenitis, omasitis, and abomasitis; lymphocytolysis in lymphoid organs; and nephrosis. Hepatic arsenic and lead levels in cases 1-3 were 20, 24, and 31 ppm, and 8.3, 25, and 9.4 ppm, respectively. Lesions in the forestomachs and lymphoid tissues have been rarely reported in cases of lead arsenate poisoning. In southern South America, these lesions are indistinguishable from those produced by Baccharis coridifolia, a toxic plant that contains macrocyclic trichothecenes, thus these conditions should be considered in the differential diagnosis of necrotizing lesions in alimentary and lymphoid organs.

“…Belirtilen alanlarda tüketilen arsenik evcil hayvanlarda sık sık zehirlenmclere kaynak oluşturduğu gibi bu metalin kasıtlı amaçlarla verilmesiyle oluşan, ya da benzeşim ve doz hatalardan kaynaklanan zehirlenmeler de ihmal edilemeyecek boyutlara ulaşır (3,24).…”

“…Son yıllarda arseniğin çeşitli amaçlarla kullanımı giderek azalmakla beraber, halen insektisid, yabani ot iIacı, ağaç prezervatifi, hayvanlarda gelişme hızlandırıcı amaçlarla yem katkı maddesi olarak, boya endüstrisi ve seramikçilikte azımsanmayacak ölçülerde kullanılmaktadır (7,20,30). Belirtilen alanlarda tüketilen arsenik evcil hayvanlarda sık sık zehirlenmclere kaynak oluşturduğu gibi bu metalin kasıtlı amaçlarla verilmesiyle oluşan, ya da benzeşim ve doz hatalardan kaynaklanan zehirlenmeler de ihmal edilemeyecek boyutlara ulaşır (3,24). Ülkemizde evcil hayvanlarda arsenikle zehirlenme olaylarının varlığına ya da sıklığına ilişkin yapılmış herhangi bir yayına rastlanamamıştır.…”

“…Arsenik evcil hayvanlarda sık sık zehirlenmc1ere neden olan metallerden biridir. Çeşitli inorganik ve organik bileşikleri halinde doğrudan insektisid, herbisid ve akarisid olarak kullanılmasına ko~ut olarak boya endüstrisi, süs kağıtçılığı, seramikçilik ve ağaç prezervativi olarak geni~bir uygulama alanı bulmu~olması belirtilen önemini daha da artırmaktadır (3,15,17,24). Ayrıca, cinayet ve intihar amacıyla fazlaca başvurulan maddc1er~en birisidir.…”
