Food and Waterborne Parasitology publishes high quality papers containing original research findings, investigative reports, and scientific proceedings on parasites which are primarily transmitted to humans via the consumption of food or water. The relevant parasites include protozoa, nematodes, cestodes and trematodes which are transmitted by food or water and capable of infecting humans. Pertinent food includes products of animal or plant origin which are domestic or wild, and consumed by humans. Animals and plants from both terrestrial and aquatic sources are included, as well as studies related to potable and other types of water which serve to harbor, perpetuate or disseminate food and waterborne parasites.

Foodborne and waterborne diseases are illnesses caused by bacteria that are present in contaminated food and water sources. Foodborne diseases often take the form of "food poisoning," with vomiting and diarrhea. Waterborne diseases can manifest as either food poisoning or pneumonia, depending on the bacteria involved. Some foodborne and waterborne diseases come from obvious sources, like untreated water or water contaminated with human or animal sewage. Tainted water will cause a food poisoning illness.
