For one day events, bring enough extra utensils for the following: to change out utensils every four hours, to replace dropped utensils and to replace other contaminated utensils. You must change utensils that come in contact with potentially hazardous foods every four hours if utensil cleaning facilities are not available on site.
If your event is more than one day and you are applying for a temporary food establishment permit, you need to have a plumbed three compartment sink or commercial dishwasher to wash and sanitize utensils. If the event venue does not have a plumbed three compartment sink or commercial dishwasher, you must have a commissary agreement with a local commercial kitchen. If you have a food establishment permit in Whatcom County, you may use your dishwashing facilities for utensil cleaning.
Some menu items, like smoothies made with dairy, soy or protein products, require frequent cleaning and vendors will need access to a plumbed three compartment sink at the event site. Whatcom County does not allow the three tub method for utensil washing and sanitizing at temporary events.
