OCHRATOXIN

Toxin Characteristics

This toxin is produced by some species of Penicillium and Aspergillus in cereal grains. Ochratoxin A, affects kidney function.

Crops and Weather Conditions

Toxin production occurs over a wide temperature range. Optimal conditions for ochratoxin production are at a temperature range between 68-77� F and a crop moisture content of 16% or above.

Impact on Animal Health

Ochratoxin-contaminated feed has its major economic impact on the poultry industry.

Chickens, turkeys and ducklings are susceptible to this toxin

Clinical signs of avian ochratoxicosis are similar to other toxins and generally involve reduction in weight gains, poor feed conversion, reduced egg production, poor egg shell quality and kidney poisoning.

Acute toxicity does not seem to constitute a problem in cattle.
