Cattle, sheep, dogs, game birds.


[etiology.gif] Etiology
Accidental ingestion of fertilizer whilst still in sacks or immediately after spreading (from clumps of fertilizer left after treatment of cultivated land).
Natural phosphates contain fluoride which must be removed before the preparation is sold for commercial use as fertilizer.


[toxic.gif] Toxicity
Compounds of very low toxicity. Need to ingest considerable quantities before toxic signs present.
Toxic doses not well known oral doses of 250 mg/kg per day of phosphates or super-phosphates for 30 days do not cause adverse effects in sheep. At similar doses, however, slag does cause a transient diarrhoea.
