Don't deprive yourself of eating oysters because you are afraid of poisoning food.
That would be a shame, especially if you love it.
No, do not deprive yourself because there is a trick to never get sick with oysters.
You just need a little lemon.
1. lemon the oysters you have to taste,
2. eat them 15 min later.
In 15 minutes, the lemon had time to act as a food disinfectant. When you taste your oysters, there is no longer any danger of poisoning (unless your seafood was not fresh!).
You can do the same with other seafood, fish, meat, salads, vegetables, if you like the lemony taste of course.
This remedy also works for water that seems a bit "doubtful" to you. You just need to put 15 cl of fresh lemon juice per liter of water.
