Raw Fish Safety (bacteria and parasite education for sushi lovers)

The two risks we need to address to serve fish raw at home are bacteria and parasites. Bacteria ======= When the fish dies, bacteria start decomposing its flesh and multiplying very quickly. Bacteria growth can be minimized by bleeding and gutting the fish immediately after death, and storing it on ice. As the temperature drops, bacteria growth drops off exponentially. Exposing the fish flesh to air introduces more bacteria, so you want to fillet the fish as close to serving raw as possible. To ensure that these conditions are met, buy your fish from a high end fishmonger who has a good turn over, and from a fishmonger who is comfortable answering your questions. Ask the fishmonger when the fish was filleted. If the answer is “today”, you are in good hands. But please don’t panic if the fish came to the store a few days ago. Whole fish can last very well on ice. If you want to eat the fish raw, I suggest you do so within 24 hours after purchase. Keep the fish between ice-packs as soon as it’s in your possession (even in the car and in your fridge). Parasites: ======== Now let’s talk about parasites. Although the kingdom of marine parasites is extremely diverse, the only 3 that you need to worry about are are cod worm, anisakis, and tapeworm. Those can live in mammals, which is you. The other ones can’t, so they are harmless. Fish that are prone to these species of parasites should not be consumed raw (at least not without freezing). Of particular concern are freshwater fish and pacific fish, like wild salmon. The incidence of parasites in some of those fish is as high as 90%. Safe Species: =========== Now that I’ve ruined fish for you, let me assure you that not all is lost. Among wild denizens of the seas, tuna, scallops, and oysters are free from cod worm, anisakis, and tapeworm. Farm-raised fish that are aqua-cultured in huge pools (vs the ocean) are completely parasite free. This includes arctic char, and Mediterranean bass (branzino). Farm raised salmon is raised in cages in the ocean. Whether these fish pose a parasite risk or not depends on how the farm is set up. Since it’s not easy to find out, it’s best to freeze farm-raised salmon before eating it raw. Wrap it tightly in plastic, place in the freezer bag and freeze. 7 days in the home freezer is sufficient to kill parasites. To defrost, move it to the fridge 24 hours before serving. I can’t get a straight answer from any source about parasites in hamachi. But since the only hamachi available to me in Boston is imported from Japan in the frozen state, I don’t need to worry about parasites. Does freezing solve all the problems? =============================== I know what you are thinking -- can’t we just freeze all fish? In sushi restaurants, most fish is frozen, but they have a freezing technology that doesn’t allow water to crystallize. This prevents fish from turning mushy. Freezing halibut, fluke and most other white fish in a home freezer completely destroys their texture. But salmon freezes quite well in a home freezer because it’s fatty. Oh, and by the way, the freezer section in your supermarket is not a good option for raw consumption. Although the parasites in those fish are long dead, the bacteria are not. Freezing pauses bacteria growth, but doesn’t kill bacteria. Most of those fish have been through a lot of transportation. In some cases, they were frozen and defrosted numerous times. Even if they were safe, their flesh is often mushy and the flavor is dull. Cured fish ========= If you like your fish cured in acid or salt, like ceviche or gravlax, keep in mind that unlike heat, acid and salt do not kill parasites. So the same precautions that apply to raw fish, apply to cured fish.

Great short summary of information Just one concern. To kill parasites it needs to be frozen at -15°C for not less than 96 hours, or -20ºC for 24 hours or -35ºC for 15 hours. It’s hard to be done at home. Also, in companies, they stack the water dripping products on top of each other resulting uncertainty of maintaining the freezing temperatures. Causing some parasites to survive even though it’s frozen before. It’s something that industry needs very strict regulation. Remember Japan is the most country that gets this fish parasites since they eat fresh also. Not sure if other country sushi restaurants are using fresh or frozen. But it is not an easy job and each government needs to step up and make industry or related restauranteurs realize and get educated repeatedly considering how much people are eating sushi and sushi products in the market.

*The US Food and Drug Administration (FDA) on the other hand advises freezing fish at either minus 20 degrees for seven days, or minus 35 degrees until solid and then storing at minus 20 degrees for 24 hours.

Tony Wiltshire

Helen Rennie
Helen Rennie - 2 years ago
curing it will help with bacteria, but not with parasites. freezing will help with parasites, but not with bacteria. Are you shopping at a high end fish market or a supermarket? If it's a supermarket like wagman's or whole foods, you might be able to get a very high quality product. At least where I live, those two supermarkets have very good fish. If it's regular supermarket, I wouldn't get anything either fresh or frozen to serve raw. Keep in mind that freezing only helps with parasites. You really don't know how that fish was handled unless it's explicitly labeled that it's intended for raw consumption. Whole foods sells some frozen salmon intended to be used raw. If the people selling you the fish, are not comfortable telling you that you can eat it raw, it's probably not a good idea.
Tony Wiltshire
Tony Wiltshire - 2 years ago
Yes I knew that is never a good idea I just wanted to clarify. So basically you are saying fresh previously frozen high end farm raised salmon is ready to eat raw correct? If it hasn't been frozen follow the instructions in the video. I've been looking at curing the salmon as an extra precaution but I am not really sure what the taste/texture difference would be. Could you enlighten me if you have tried both? I've had smoked salmon many times. Again thank you so much for the lesson.
Helen Rennie
Helen Rennie - 2 years ago
No, never freeze the fish twice. If your salmon was already frozen once that's sufficient to kill parasites.

Helen Rennie
Helen Rennie - 3 years ago
if it's farm raised, the chance of parasites is very slim. if it's wild, I would never used it for raw dishes without freezing. that being said, I don't know if I'd use walmart's fish for raw preparations. You want fish that was filleted as recently as possible. I doubt walmart's have a fishmonger in every store. their fish was likely filleted 3-4 days before you bought it (that's the best case scenario ;)

Hi,
First of all thank you for your helpful advise, second what will happened for bacteria if I eat raw fish with alcohol
heberildo
heberildo - 2 years ago
Does bacteria grow only on surfaces or also in the flesh? Will salting the surfaces of fish for ~15-20 mins kill most bacteria?
Helen Rennie
Helen Rennie - 3 years ago
ALL bacteria will survive freezing just fine, not "some" bacteria. And only SOME parasites are really harmful. Once your fish has grown enough bacteria, there is nothing you can do besides cook it. if you are worried about parasites, don't eat wild salmon raw. the odds of getting a parasite from farm-raised salmon are VERY low and if you freeze it, that risk goes down even further.
Helen Rennie
Helen Rennie - 3 years ago
I think you are confusing 2 issues. Freezing doesn't kill bacteria at all. It kills parasites. Alcohol doesn't kill parasites. It could slightly reduce the amount of bacteria, but is in no way a reliable method.
Helen Rennie
Helen Rennie - 3 years ago
it all depends on how much bacteria and how much alcohol ;) i wouldn't recommend eating spoiled fish and hoping to make it safe by drinking vodka (wine is way too weak to kill bacteria).

The procedure is different depending if it's whole fish, gutted/bled whole fish, fish fillets or already made sashimi/sushi pieces. Temperature it's stored in also matters. With already made sushi/sashimi, it should be eaten/disposed of within 24 hours.

Helen Rennie
Helen Rennie - 4 years ago
for hot smoked salmon, parasites and bacteria are not an issue because it's cooked to a high enough temperature to kill them. for cold smoked salmon, the same safety issues apply as to raw salmon. the brining process (that happens before smoking) would kill the bacteria, but will not necessarily kill the parasites, so if you are making smoked salmon yourself out of wild salmon, it's best to freeze it before or after the smoking process. if you are buying cold smoked salmon, it's already been through all the safety measures.

Yes, gravlax freezes great! I would recommend curing the fish first, then drying it thoroughly, wrapping in plastic, sealing in a freezer bag and freezing. It will lose less moisture after it was cured. If you make gravlax with wild salmon, I would strongly recommend freezing. Salt doesn't kill parasites.

Helen Rennie
Helen Rennie - 4 years ago
+vavavvavava Unfortunately, I don't have a list to point you to, but if I find something I'll let you know. The reason a list is so hard to put together is that the origin of the fish makes a difference. Hamachi is farm-raised in Japan, so it's fine to eat raw (no parasite issues). Mackerel can have parasites, so you need to freeze it first. Mackerel is usually salted in sushi restaurants. You can get videos on-line how to prepare it. If you plan to salt it, I would do that first and THEN freeze it. Salt will help it retain moisture during freezing.

+Kari Coad Thanks Kari! I owe everything that I know about parasites to a wonderful German professor of parasitology, Dr. Harry Palm. We started corresponding many years ago because I wanted to learn about this subject. When he came to a conference in Boston, we went fish shopping together and he showed me all sorts of creatures most people never notice. I realize how disgusting this seems at first (it took me years to get over it), but it's no reason to stay away from fish, even raw fish. It's just important to understand what's a real risk to your health and what's just icky.
