Depends if it's alive or dead!
Raw meat can get bacteria in it after one hour at room temp.
No. However, if they are removed from the refrigerator and are cold they will need to cook longer to reach the proper temperature for doneness (170F). Allowing meat, fish and poultry to reach room temp is okay as long as the food is not held at that temp (about 80F) for long. Reason is bacteria love raw meats at room temp and multiply like crazy if left warm too long.
Raw chicken should not be permitted to stand at room temperature for any length of time. Keep it chilled below 40 F (4.5 C) until you are ready to cook it.
Green means Raw, so in a sense they are saying "raw, raw" shrimp.
Raw shrimp cannot be refrozen. This is because the raw shrimp will get freezer burned and could grow harmful bacteria.
As long as the heads are not spoiled, the dogs will enjoy the shrimp head will no ill effects.
Simmer the shrimp until they appear white instead of translucent. When shrimp is raw it is sort of floppy and appears to be in the shape of a comma. When fully cooked they will shrink up a bit and form a tight firm curl.
NO!!
There are approximately 28.35 grams in 1 ounce of raw shrimp.
The recommended amount of shrimp per person is 1 pound of raw shrimp or 1.2 pound of cooked. For 60 people you would need 60 pounds of raw or 30 pounds of cooked shrimp.
That would not be a good idea. If you start the chicken first and get it almost completely cooked and then add the shrimp, you would be okay. If you start them at the same time, the shrimp will be terrible overdone and rubbery. If you pull the shrimp out as soon as it is done, it will be contaminated by the still raw chicken.
