Q

All are vehicles of contamination except:

A. Refrigeration shelf

B. Blast chiller

C. Kitchen counter

D. Takeout container

A

Answer: B. Blast chiller

Vehicles of contamination facilitate the movement of microorganisms from one medium to another. Blast chillers are not vehicles of contamination because they are used to freeze food at a very fast rate. At this extremely low temperature, nearly all harmful microorganisms cannot thrive and can therefore not be transferred to another medium
