toxemia

(tŏksē`mēə), disease state caused by the presence in the blood of bacterial toxinstoxin,
poison produced by living organisms. Toxins are classified as either exotoxins or endotoxins. Exotoxins are a diverse group of soluble proteins released into the surrounding tissue by living bacterial cells. Exotoxins have specific reaction sites in the host; e.g.

 or other harmful substances. The effects of the bacterial toxins known as endotoxins are relatively uniform, regardless of which bacterial species the toxin comes from, and are separate from the effects caused by the infecting bacterium itself. A small amount of endotoxin (released by dead bacteria) produces one or more fever episodes, thought to be caused by release of a fever-inducing substance from damaged white blood cells. Large quantities of endotoxin cause shock and death. Exotoxins are proteins released by bacteria that have specific effects on target tissues, e.g., botulinus toxin affects the nervous system.

, invasion of the bloodstream by virulent bacteria that multiply and discharge their toxic products. The disorder, which is serious and sometimes fatal, is commonly known as blood poisoning.

The term toxemia is also used for a disorder occurring during the latter half of pregnancy characterized by high blood pressure, the appearance of protein in the urine, and edema. If not treated it can result in convulsions and coma. The cause of toxemia of pregnancy has not been established with certainty. See also eclampsiaeclampsia
, term applied to toxic complications that can occur late in pregnancy. Toxemia of pregnancy occurs in 10% to 20% of pregnant women; symptoms include headache, vertigo, visual disturbances, vomiting, hypertension, and edema.

Installed near the front end of the chicken-processing line, cameras look for defects such as improperly bled birds and those afflicted by systemic diseases, like septicemia and toxemia. Unique software and algorithms provide the intelligence for translating visual data from the system's cameras into the appropriate mechanical commands for dispensation of each chicken.
