17. Provide any additional details about the incident
(eg. description of the frequency and severity of the symptoms
6.0 yr lactating female weighing 1200.0 lb. Was in good health previously. Exposure involved unknown amount orally . The exposure was yard use, and occurred at animal owner field/pasture. One cow died yesterday. He has seen some tumbleweeds in the pasture and there is Kochia that they could have ingested. It's very possible that the effects seen could have been a result of ingestion of Kochia plants, or it could be from nitrates. Asked about potential lead exposure, the caller said that it did cross his mind, since he did have cattle in the past that were exposed to an old battery and the symptoms observed were similar. There are no batteries in the pasture though, that he is aware of.

19. Provide supplemental information here
Both of these herbicides should not be a risk to grazing livestock, especially if they were dried before they entered the pasture. There are no grazing restrictions for beef cattle with either product. Because the time course was poorly consistent, the amount was unknown consistent, and the findings were poorly consistent, this substance was considered to have low likelihood of causing the clinical situation.
