Foodborne Parasites

In a tight association between species known as parasitism, one organism—the parasite—lives on or inside another—the host—doing harm to it while being physically suited to this mode of existence. E., an entomologist, Parasites include single-celled protozoans like the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. According to O. Wilson, parasites are "predators that eat prey in units of less than one There are six main parasitic methods used to take advantage of animal hosts: parasitic castration, direct transmission (by contact), trophically transmission (by consumption), vector transmission, parasitoidism, and micropredation. An important categorization axis relates to invasiveness: an ectoparasite resides on the host's surface whereas an endoparasite lives inside the host's body. While parasitism is a form of consumer-resource interaction, similar to predation, it differs from predation in that, with the exception of parasitoids, parasites are normally considerably smaller than their hosts, do not kill them, and frequently survive in or on their hosts for a prolonged length of time. Animal parasites are highly specialised and reproduce more quickly than their hosts. Considering industry to market practises, food safety considerations include the origins of food including the practises relating to food labelling, food hygiene, food additives and pesticide residues, as well as policies on food additives and pesticide residues. Classic examples include interactions between vertebrate hosts and tapeworms, flukes, the malaria-causing Plasmodium species, and fleas.
