The Chicago Rabbinical Council is concerned about the cleaning process in which it is possible that a utensil which was used for non-kosher will be cleaned together with utensils used to prepare kosher beverages. There are many reasons given why this may not be an issue:
- Only two utensils in Starbucks ever come into contact with non-kosher. Therefore, we can rely that any non-kosher is nullified in the cleaning process.
- Even those utensils that are used with non-kosher products are generally separated with wax paper and don’t actually come into contact with non-kosher.
- The non-kosher sandwiches are a davar gush (a hard item). However, many still consider it a kli sheini which does not transfer taste.
- Soap is used in the cleaning process which would allows one to rely on Nosein Taam Lifgam (The non-kosher taste is rendered inedible by the soap so it does not transfer.
- Many consider the cleaning process to be irui kli rishon (pouring) which will only transfer taste k’dei klipah (a minimal transfer) this minimal taste transfer will subsequently be batul b’shishim (nullified).
- All the equipment is sanitized after being cleaned
Although the cRc recommendation is based on the stringent view they concede that one may rely on many of the reasons given above. For more information on the position of the cRc please see The cRc Guide.
