How to prevent food poisoning by being careful not to touch oysters

Oyster food poisoning

It is important to heat food to prevent food poisoning.

Oysters are delicious, but they are easy to eat and pose a risk of food poisoning. Heating is the most important way to prevent food poisoning.

The main causes of food poisoning in oysters are norovirus, shellfish poison, and Vibrio parahaemolyticus. Norovirus and Vibrio parahaemolyticus are killed in most cases by heating. Shellfish poison will not be killed by heating, but oysters from areas where shellfish poison has been detected are stopped from being shipped, so oysters contaminated with shellfish poison rarely reach the market.

Shellfish poison and Vibrio parahaemolyticus often occur from spring to summer, while norovirus often occurs in winter, when oysters are in season. If you eat raw food without heating it properly, you can easily get food poisoning.
Symptoms of food poisoning include vomiting, diarrhea, fever, and in the case of shellfish poisoning, paralysis. If the symptoms are severe, dehydration, bloody stools, and loss of consciousness may occur, so it is necessary to see a medical institution.

Properly heating oysters can prevent the risk of food poisoning, but cooking utensils such as cutting boards and knives can become infected. Therefore, it is important to wash your cooking utensils properly and keep them clean.

Do not eat raw oysters that are prepared for heating.

Avoid eating raw oysters that have been prepared for heating, as this can be dangerous. The difference between eating raw or heating depends on the place of production. Depending on the sea area, oysters are divided into those that are safe to eat raw and those that are not.

Oysters intended for raw consumption must be strictly hygienic, including expiration dates and storage methods, and must also be labeled as to the area where they were harvested. Therefore, please avoid eating at your own discretion.

Also, even if you are eating raw oysters, it is best to refrain from eating them if you have a cold or are not feeling well, as they can easily irritate you.

Oyster heating time

Properly cooking oysters can prevent food poisoning. For example, norovirus can be sterilized by keeping the core temperature at 85℃ and heating it for 90 seconds or more.

If the food is undercooked and half-cooked, you may get food poisoning, so be sure to heat it properly before eating. However, be careful not to overcook as the meat will become tough if overcooked.

How to defrost shucked oysters

Defrost frozen shucked oysters in lukewarm water or running water. Thaw in lukewarm water for 15 seconds to 20 seconds, and in running water for 45 seconds to 1 minute. Once the surface has melted, drain it into a colander and wipe it dry with kitchen paper.

You can cook it deliciously without completely thawing it until the ice on the surface has melted and the center is slightly frozen. If you defrost it too much, the flavor will escape, so the key is to thaw it only half way.

Also, soaking the meat in alcohol while partially defrosted will reduce the odor and make the meat more plump. Arrange the half-thawed oysters on a deep plate and soak in enough alcohol to cover the oysters for 30 minutes to 1 hour.
This will prevent the meat from shrinking even when heated, making it fluffy.

How to defrost oysters in the shell

Defrost frozen oysters in the shell in the microwave. Wash them with water, being careful not to injure them with the shells, and place them on a plate with the deep shells facing down. Thaw by heating until the shell opens.

The approximate time it takes to defrost 3 oysters is about 3 minutes at 500W. The thawing time will vary depending on the amount and size, so it's best to keep an eye on it.

It is important not to thaw the oysters too long, as the flavor of the oysters will leak out and cause odor.
