Use single service items to distribute samples to customers. Examples are paper plates, cups, napkins, plastic utensils, wooden sticks or toothpicks. The customer can then dispose of single service items once the product is consumed. Vendors should bring a garbage container for this purpose.
Minimize bare hand contact with cut produce by using tongs. If single service gloves are used, change the gloves often to prevent soiled gloves from cross-contaminating samples.
Vendors should try to avoid contamination of samples by customers. In order to control this, vendors can keep control of the sample plate and offer samples directly to customers.
If the plate of samples is to be self-serve, then the plate should be covered, for example with a clear plastic dome.
