Warning Signs Of Food Poisoning

Fever

A measurable fever isn't necessary to prove someone has food poisoning. However, most pathogens and organisms that cause food poisoning will also trigger a fever reaction in the body. This reaction might be mild enough that it's barely noticeable. In more serious cases, an individual's temperature might rise by a few degrees. Fevers occur when the core temperature of the individual's body becomes higher than it usually is. It is important to note food poisoning isn't the only illness that can lead to a fever. The body tends to raise its core temperature when it experiences any infection or illness from an organism. The substances that produce a fever are called pyrogens. When an individual's immune system detects their body is fighting off an illness, one of its many responses is to release a flood of pyrogens into the bloodstream. The presence of pyrogens leads to a rise in body temperature. As soon as the body's temperature increases, the white blood cells undergo a significant increase in their overall activity level, which means they're more actively capable of fighting the infection.
