Which of the following is NOT a disease that can be contracted by the food-borne route?

  1. Salmonellosis

  2. Giardiasis

  3. West Nile Virus Neuroinvasive Disease

  4. Hepatitis A

The correct answer is: West Nile Virus Neuroinvasive Disease

West Nile Virus Neuroinvasive Disease is primarily transmitted through the bite of infected mosquitoes, making it distinct from the other diseases listed, which are contracted through contaminated food or water. Salmonellosis, Giardiasis, and Hepatitis A are all illnesses associated with foodborne transmission. Salmonellosis is commonly caused by consuming food contaminated with Salmonella bacteria, often found in raw or undercooked eggs and meat. Giardiasis is caused by the Giardia parasite that can be ingested through contaminated food or water. Hepatitis A is a viral infection that can be contracted through the consumption of food or water contaminated with fecal matter from an infected person. Thus, West Nile Virus Neuroinvasive Disease does not fit the foodborne transmission category, solidifying the distinction between it and the other diseases mentioned.
