Food-borne illness and invasive organisms

[charlesxkinetic]

Is there any terminology/definition difference between "Food-borne illness" and "Food poisoning"?

The term usually does not include the consequences of invasive organisms acquired via the food supply (though the broader term foodborne illness accommodates these conditions.)

However, I want to clarify the meaning of "invasive organism". Is parasites such as tapeworm an example?
Sorry for asking such a simple question. Thanks.

It depends - the effective definition isn't a clear-cut line.

You can pick up organisms, like Salmonella, and have it called food poisoning or a food-borne illness. If you pick up some sort of toxin, it's likely to be called poisoning.

Thanks! In addition, I want to know something more about "non-toxin" examples for more interpretation on conditions belongs to "Food-borne illness" but not "food poisoning".
