Food intoxication is when someone becomes ill from eating food that contained toxins that were produced by bacteria.

The Microtox test was introduced in 1979 as a microscale acute toxicity test. It tests the effect that toxins contained in a water or soil sample has on the bioluminescence of the bacteria V. fischeri. Although the test can detect toxins in the sample it fails in the fact that it cannot tell you what the toxin is.

Salts have not toxins; don't confuse toxins with toxic substances.
