Naturally occurring toxins in foods

Naturally Occurring Food Toxins

Although many foods contain toxins as a naturally-occurring constituent or, are formed as the result of handling or processing, the incidence of adverse reactions to food is relatively low. The low incidence of adverse effects is the result of some pragmatic solutions by the US Food and Drug Administration (FDA) and other regulatory agencies through the creative use of specifications, action le...

Naturally occurring toxins in feedstuffs: Center for Veterinary Medicine Perspective.

The objectives of this review are to provide 1) information on the FDA Feed Contaminants Program, 2) the legal history of aflatoxins and their current action levels, 3) a report on the levels of aflatoxins, fumonisins, vomitoxin, ochratoxin A, and zearalenone in domestic and import surveillance samples of feed during fiscal years 1989 through 1992, and 4) information on naturally occurring toxi...

Naturally occurring ehrlichiosis in Egyptian dogs

Canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. Eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...

Tethering Naturally Occurring Peptide Toxins for Cell-Autonomous Modulation of Ion Channels and Receptors In Vivo

The physiologies of cells depend on electrochemical signals carried by ion channels and receptors. Venomous animals produce an enormous variety of peptide toxins with high affinity for specific ion channels and receptors. The mammalian prototoxin lynx1 shares with alpha-bungarotoxin the ability to bind and modulate nicotinic receptors (nAChRs); however, lynx1 is tethered to the membrane via a G...
