I work in a long term care facility and every holiday season we have a ton of visitors, family members, church groups etc. come through with candies and baked goodies that they leave for the residents. We do LOVE all of our visitors, however the food they bring in is becoming an issue. We have several diabetic residents, some with allergies, as well some that don't have a regular diet and require softened or even pureed foods. And it is a violation of privacy to put signs on doors or tables saying that this specific resident has a medical issue so please don't give them such and such foods. So how do we ask them to NOT bring food in? Instead bring something useful such as blankets, socks, decorations, ornaments, things that the residents will appreciate more than an unhealthy snack they gobble down without thinking? I want to be polite but also taken seriously. Thanks in advance!
