Final answer:
Hepatitis B is not one of the reportable illnesses identified in an ill employee policy related to food handling because it is not typically transmitted through food.
Step-by-step explanation:
The illness that is not one of the reportable illnesses identified in an ill employee policy from the given options is Hepatitis B (B). Hepatitis A (A), Norovirus (C), and Salmonella (D) are commonly reportable due to their potential for foodborne transmission. Hepatitis B, while a serious illness, is not typically spread through food handling. Contrary to Hepatitis A, which is transmitted via the fecal-oral route and can contaminate food if those infected do not follow proper hygiene, Hepatitis B is primarily transmitted through blood and body fluids, making it less of a concern in the context of food preparation and handling.
