SOLANUM POISONING IN CATTLE
 
Description    Some members of the plant genus SOLANUM, nightshades, are toxic when eaten causing gastrointestinal and/or CNS signs. S. MALACOXYLON in South America causes a chronic wasting and calcifying disease called Enteque Seco. Chronic ingestion of S. DIMIDIATUM, S. KWEBENSE, S. FASTIGIATUM or S. BONARIENSE can cause cerebellar degeneration. S. MELONGENA (eggplant) has caused tremor and cerebellar signs in pregnant cows and their newborn calves; death has followed seizures. S. MACROCARPON in South Africa was associated with gastrointestinal and nervous signs.
