....now we are told we need policies and education. Thanks.
It would seem appropriate that they be made in the kitchen, since there is one on every unit - at our LTAC, they were made in the med room - and that was a PITA and a mess besides.
Anyway - so far as policies,
You likely need a 'disinfection procedure' for the blender (hot soap and water, followed by rinsing with hot water)
A storage and dating procedure for the berries (the JC seems to like 3 days) so the berries will be stored in labeled containers (to prevent cross contamination / allergies / etc) and labeled with the date of purchase and expiration date (three days later). Log on the front of the storage refrigerator to document temperature checks daily and clean up / storage.
And maybe a food handler's permit for your CNAs, if it's required to work fast food where you're at.
That seems like it would be sufficient, but ymmv.
