Contamination is the exposure of the substance to polluting and harmful particles. At salad bars, customers must be provided with gloves, a sneeze guard, and sanitizer for preventing contamination.
Contamination is the state of getting infected or spoiled due to various factors that can affect the organism that can lead to disease. Undesirable factors like bacteria, viruses, dust, parasites, fungus, etc. are contaminating agents.
At food stalls, the rate of contamination can be reduced by the use of the sneeze guard that acts as a shield between the customer's face and the food, gloves to avoid direct touching the food with bare hands, and hand sanitizer to kill and disinfect the open skin area from microbes.
Therefore, gloves, a sneeze guard, and sanitizer can prevent contamination.
