School districts; require all schools to have epinephrine auto-injectors in every building and cafeteria.

HB 339 requires all Mississippi public schools to maintain epinephrine auto-injectors in every educational building, central administrative office, and cafeteria, stored securely but accessibly. It mandates that school districts adopt policies for storing, administering, and disposing of these devices, with only trained school staff (under licensed medical supervision) permitted to use them during anaphylactic emergencies. The bill defines "anaphylaxis" and specifies that trained personnel must be at least 18 years old and certified via standardized protocols. The State Department of Health, with the State Superintendent, must develop guidelines for these policies. The law directly affects all public K-12 schools and their staff in Mississippi.
