The US Food and Drug AdministrationвЂ™s вЂњBad Bug BookвЂќ (Foodborne Pathogenic Microorganisms and Natural Toxins Handbook) includes basic facts on foodborne pathogenic microorganisms and natural toxins. An in-depth discussion of the candling method with finfish and molluscs is described. The US Food and Drug AdministrationвЂ™s вЂњ BAMвЂќ (Bacteriological Analytical Manual) has a chapter on Parasitic Animals in Foods which discusses techniques for examining foods for the presence of parasites. includes the life cycles of common parasites in freshwater and marine fishes, transmission, and prevention. Additional Links for More Information:ДЄ California Sea Grant publication вЂњ Fish Parasites and Human Health, Epidemiology of Human Helminthic InfectionsвЂќ by J. The health risk from parasites is far less than the risk from bacterial pathogens and mishandling of seafood. However, they do not completely eliminate the hazard, nor do they minimize it to an acceptable level. Trimming away the belly flaps of fish or candling and physically removing parasites are methods for reducing the numbers of parasites.

FDAвЂ™s Food Code recommends these freezing conditions to retailers who provide fish intended for raw consumption. Flukes appear to be more resistant than roundworms.ДЇreezing and storing at -4вЏ (-20вЊ) or below for 7 days (total time), or freezing at -31вЏ (-35вЊ) or below until solid and storing at -31вЏ (-35вЊ) or below for 15 hours, or freezing at -31вЏ (-35вЊ) or below until solid and storing at -4вЏ (-20вЊ) or below for 24 hours is sufficient to kill parasites.

For example, tapeworms are more susceptible to freezing than are roundworms. The temperature of the freezing process, the length of time the fish is held frozen, and the type of parasite appear to be the most important factors.

The effectiveness of freezing to kill parasites depends on several factors, including the temperature of the freezing process, the length of time needed to freeze the fish tissue, the length of time the fish is held frozen, the fat content of the fish, and the type of parasite present. The process of cooking (145вЏ for 15 seconds) raw fish sufficiently to kill bacterial pathogens is also sufficient to kill parasites. Some products that have been implicated in human infection are: ceviche (fish and spices marinated in lime juice) lomi lomi (salmon marinated in lemon juice, onion and tomato) poisson cru (fish marinated in citrus juice, onion, tomato and coconut milk) herring roe sashimi (slices of raw fish) sushi (pieces of raw fish with rice and other ingredients) green herring (lightly brined herring) drunken crabs (crabs marinated in wine and pepper) cold-smoked fish (lox) and, undercooked grilled fish. Among parasites, the nematodes or roundworms ( Anisakis spp., Pseudoterranova spp., Eustrongylides spp.В and Gnathostoma spp.), cestodes or tapeworms ( Diphyllobothrium spp.) and trematodes or flukes ( Chlonorchis sinensis, Opisthorchis spp., Heterophyes spp., Metagonimus spp., Nanophyetes salminicola and Paragonimus spp.) are of most concern in seafood. Parasites (in the larval stage) consumed in uncooked, or undercooked, unfrozen seafood can present a human health hazard. Home freezers range from 0вЏ to 10вЏ and may not be cold enough to kill parasites. Alternatively, freeze the fish to an internal temperature of -4вЏ for at least 7 days to kill any parasites that may be present. When preparing these products, use commercially frozen fish. Parasites become a concern when consumers eat raw or lightly preserved fish such as sashimi, sushi, ceviche, and gravlax. Parasites do not present a health concern in thoroughly cooked fish. Just as there are risks to eating raw or undercooked meat, there are also risks with eating raw, undercooked, pickled, and lightly or cold-smoked seafood dishes. Protozoa are single-cell animals, and cannot be seen without a microscope. These worms vary in size from barely visible to several feet in length. Parasitic worms include roundworms (nematodes), tapeworms (cestodes) and flukes (trematodes).

There are two types of parasites that can infect people through food or water: parasitic worms and protozoa.

They are as common in fish as insects are in fruits and vegetables. All living organisms, including fish, can have parasites.
