The correct answer to this open question is the following.
The potential kitchen contaminant I am going to choose is the most common: people´s hair. That is why the first rule for people who work in the kitchen is to have their hair neatly tied back and to wear some kind of hair protection. 
So this idea supports the way I would establish the seven principles of the HACCP (Hazard Analysis Critical Control Point) procedure, in order to eliminate this contaminant from my kitchen.
People's hair has many invisible substances that could be dangerous when preparing the ingredients for the food. So a more strict control and application of the principles of the HACCP would create a culture of prevention.
The seven principles of HACCP are 1) Conduct a hazard analysis. 2) Identify the critical control points. 3) Stablish critical limits. 4) Monitor the critical control points. 5) Establish a corrective action. 6) Verification. 7) Keep records. 
 
        
             
        
        
        
The concerto was a popular form during the Classical period (roughly 1750-1800). It had three movements – the two fast outer movements and a slow lyrical middle movement. The Classical concerto introduced the cadenza, a brilliant dramatic solo passage where the soloist plays and the orchestra pauses and remains silent.
