 In a week, what amount of mayonnaise can be bad?

Unfortunately, I can't answer your question about the amount of mayonnaise that can go bad in a week without more context. Here's why:

1. Starting point: It depends on how much mayonnaise you start with. Is it a full jar? Half a jar? A tablespoon leftover from a sandwich? The larger the quantity, the greater the potential for spoilage within a week.
2. Storage conditions: Where is the mayonnaise stored? In the fridge, at room temperature, or somewhere else? Mayonnaise stored properly in the refrigerator lasts much longer than at room temperature.
3. Open or unopened: Has the jar of mayonnaise been opened or is it still sealed? Unopened jars typically last longer than opened jars, even when refrigerated.
4. Homemade or store-bought: Homemade mayonnaise generally has a shorter shelf life than commercially produced varieties due to the use of raw eggs.

Therefore, to give you a more accurate answer, I need more information about the specific situation. Please tell me:

How much mayonnaise are you referring to?

Where is it stored?

Is it opened or unopened?

Is it homemade or store-bought?

With this information, I can provide a better estimate of how much mayonnaise might go bad within a week.
