Additional information

No data on toxicity of disulfiram to bird species (CAS No. 97-77-8) were available. Therefore, a conclusion based on an analogue approach had to be drawn. Several studies have investigated the toxicity of tetramethylthiuram disulfide (CAS No. 137-26-8), substance structurally and composition related to tetraethylthiuram disulfide, to birds under GLP conditions (Kalotás, 1995 (2), Zajak, 1995 (2) and Beavers et al., 1995). The results from the corresponding acute toxicity, dietary toxicity and reproduction tests showed absence of treatment-related mortality in different bird species. Full recovery from sub-lethal clinical symptoms (if present) was observed during the post-exposure observation period (3 days onwards for acute studies, 13 weeks for reproduction study).
