Don't eat raw or undercooked oysters or other shellfish. Fully cook them before eating, and only order fully cooked oysters at restaurants. Hot sauce and lemon juice don't kill Vibrio bacteria and neither does alcohol. Some oysters are treated for safety after they are harvested.
You can get very sick from eating raw oysters. Most Vibrio infections from oysters result in only diarrhea and vomiting. However, some infections, such as those caused by Vibrio vulnificus, can cause more severe illness, including bloodstream infections and severe blistering skin lesions.
Oysters are a versatile food that can be eaten raw or cooked. Some people like to swallow the oyster whole, but the majority of people prefer to chew them, as that is how you get the full flavor.
For beginners, it is typically best to slurp down your oyster, and while that may sound a little unappealing, it is a great way to enjoy the oyster, especially if you aren't ready for the texture.
Think of an oyster like a grape: if you don't chew the grape, you won't get the full flavor.
Slurp, Then Chew
Slurping, not chewing is a myth too frequently attached to oyster eating. Use a tiny fork to release the oyster, then pick up the shell and slurp down the oyster, chewing once or twice before swallowing. If you don't chew it, you won't experience the full flavor.
Chew, chew, chew
"An oyster is meant to be savored. Rather than swallowing whole, I recommend biting into the oyster so the full flavor profile can be experienced. Also, when consuming an oyster in the shell, remember the 'oyster liquor' is there to be enjoyed.
Look for the telltale milky sac that indicates an oyster is spawning. If it's just getting going, the sac is little more than a thin, cream-colored line less than half an inch long. If the oyster is in high gear, the sac will be large and cloudy, overtaking much of the oyster's body mass.
Am I Infected? Potentially life-threatening to most people, symptoms of Vibrio vulnificus infection occurs within 24 to 48 hours of ingestion and may include symptoms such as sudden chills, fever, nausea, vomiting, diarrhea, shock and skin lesions.
You'll probably be fine in two or three days, but since some forms of seafood-borne food poisoning can be extremely serious, it's important to get professionals involved as the illness may require more medical care.
If you are a diabetic who loves oysters, enjoy eating them but be sure they are thoroughly cooked. Do not eat raw oysters. If you do, you are asking for trouble. The source of the problem is Vibrio vulnificus, a bacterium that often thrives in waters where oysters grow.
When someone eats raw or undercooked oysters, germs that might be in the oyster can cause illness. CDC estimates that about 80,000 people get vibriosis—and 100 people die from it—in the United States every year. Most of these illnesses happen from May through October when water temperatures are warmer.
Foodie tradition dictates only eating wild oysters in months with the letter “r” – from September to April – to avoid watery shellfish, or worse, a nasty bout of food poisoning.
If there are large cracks or broken or damaged areas, throw the oyster away. There should be no gaps within the shell. If the shell is also open, the oyster is bad. Oyster shells are glossy white in color with pink and gray streaks, if yours looks greenish or brown, you should discard the oyster.
When oysters reproduce, they spawn tiny larvae that freely navigate the water column until they find an appropriate habitat with a structure to settle on. Once the larvae permanently attach to a surface, they are known as spat.
Symptoms range from mild to severe in healthy people and can lead to chronic diarrhea, dehydration and death in people who have a weak immune system. The oocysts don't survive temperatures above 164 degrees Fahrenheit, so boiling or frying shellfish would prevent infection. But they do survive chlorine quite well.
Pea crabs (Pinnotheres ostreum) or oyster crabs (Zaops ostreus) are small soft-bodied crabs that live in bivalves such as oysters and mussels. They are kleptoparasites, which means they steal food from their host to survive.
We generally tell customers oysters stay fresh up to 14 days, but our results showed the period of freshness may actually be longer. We like to err on the side of caution, so 14 days from harvest is probably a good rule of thumb to follow.
"To eat an oyster properly, tip the whole thing into your mouth straight from the shell and make sure to chew once or twice (it's okay to use a little fork if it doesn't come out first time).
Oysters: Appetizer Engagements: 3-4 oysters per person. As a second or third course (where other items are being served with the oysters): 5-6 oysters per person. For a main course (including an Oyster Roast or a Bull & Oyster Roast), figure 6-8 oysters per person. Clams: Many people serve clams along with oysters.
Once people have polished off the first round of oysters, dump out the semi-melted crushed ice in the serving bowl, and replenish with the extra crushed ice you processed earlier. Transfer the second round of shucked oysters from the sheet tray to the bowl of crushed ice. Rinse and repeat until you're out of oysters.
"When you slurp back oysters raw, they are still alive or just freshly killed or shucked prior to serving, which is why you oftentimes see them on ice," says Alex Lewis, RD, LDN, a dietitian for Baze. This ensures they are fresh when eating, so they maintain the right flavor profile, texture and nutrient density.
Mississippi Agricultural and Forestry Experiment Station food microbiologist Douglas Marshall has found eating raw oysters on an empty stomach can increase the risk of food poisoning. And taking an antacid beforehand could make the situation even worse.
