Yersinia enterocolitica O : 3 was studied throughout two central composite designs to define the effects of temperature, pH and salt concentration on bacterial growth. Mathematical models were established by response surface methodology. The impedimetric technique was evaluated for its rapidity and ability to produce detection times related to bacterial metabolism. Finally, predicted values derived from model equations were compared with observed values obtained by plate counts.
