"Smoked oysters usually are found to be a light brown color. Occasionally, however, they show a green tinge. This is not a sign of spoilage, but a natural happening due to bad weather.
When the rough seas tear and destroy the oyster beds, the oysters sink to the bottom and must feed on the green seaweed. A large amount of the chlorophyll is retained, and the smoking cure will not cover the green.
The color does not affect the delicate flavor. It has, however, caused questions of concern from consumers."
Smoked Oysters are Good for You!
Oysters are high in Omega-3 fatty acid and taurin, know to clear the arteries and benefit the central nervous system.
Oysters are not only delicious, but they're also one of the most nutritionally well balanced of foods, containing protein, carbohydrates and lipids. Remarkably, oysters contain almost zero fat. The National Heart and Lung Institute suggest oysters as an ideal food for inclusion in low-cholesterol diets.
Oysters contain more proteins and carbohydrates than milk. Oysters are an excellent source of vitamins A, B1 (thiamin), (riboflavin), B3 (niacin), C ( ascorbic acid) and D (calciferol). Four or five medium size oysters supply the recommended daily allowance of iron, copper, iodine, magnesium, calcium, zinc, manganese and phosphorus.
Zinc is a proven immunity booster and may therefore help prevent colds and flu. Optimal zinc intake also promotes growth, mental alertness and aids in proper brain function. According to the American Journal of Clinical Nutrition most people only get about one half of the recommended daily intake for zinc (15 mg. for adults). And just ONE oyster provides close to your entire daily requirements!

Smoked oysters are not good for cats. Oysters contain enzymes that may be harmful to a cats digestive system if ingested.
Flax Seed oil has a healthy mixture of different fats, mono and poly unsaturated and the oysters themselves have omega-3. All of these fats are essential to a healthy diet. The oysters are also protein rich and can be considered a good source of whole protein and Branched Chain Amino Acids (BCAAs) On a downside the canned smoked oysters are probably heavy on the sodium.
Yes, smoked oysters are indeed cooked through a smoking process. A cooked oyster will be firm to the touch which means it is safe to eat.
No, the value will always be higher in fresh than in smoked.
Yes. But should they?
No that would be stupid and really gross!
A can of oysters do expire. Expiration dates or best used by dates are marked on packages to ensure freshness before those dates.
78F to 82F
Oysters can be eaten raw as long as they are fresh. To cook them, you can boil them, bake them, or barbecue them! mmmmm... good stuff!
As long as your willing to eat them. This is a tough question to answer. If the oysters were on the verge of spoiling prior to cooking then that changes everything. It also depends on how they were cooked. Fried oysters will be fine refrigerated for a few days where as oyster stew will be good for just about a week. Seriously I wouldn't eat cooked oysters more than 3 or 4 days old.
In order to smoke oysters you need to season them and put them in a glass or ceramic baking dish on the grill or in a smoker. Use fruit wood like apple, cherry or even the alder wood chips are nice and not to strong. A good 30 to 45 minute smoke at 200 F, higher they will become tough. You need to check on them, and when they are done there is no give. You can pack them in a lot of light olive oil.
It is a good idea to avoid all raw seafood during pregnancy. Sushi, oysters etc.
