Food infections have incubation periods of days to weeks, whereas the incubation period for food intoxications is hours to days. Please select the true statements that explain this situation.

> In food infections, the microorganism has to grow in the infected human host, producing more toxins as it reproduces. > The elements that cause food intoxications, like arsenic and mercury, are extremely potent in tiny amounts causing a faster disease symptomology. > The gram-positive bacteria, the organisms causing food intoxications, grow much faster than gram-negative bacteria, the organisms causing food infections. > Food intoxications involve the ingestion of exotoxins produced by microorganisms in the food whereas food infections involve the ingestion of the microbial cells themselves.
