Fusarium mycotoxins: The major food contaminants

mLife, Volume 3, Issue 2, Page 176-206, June 2024.
Abstract Mycotoxins, which are secondary metabolites produced by toxicogenic fungi, are natural food toxins that cause acute and chronic adverse reactions in humans and animals. The genus Fusarium is one of three major genera of mycotoxin‐producing fungi. Trichothecenes, fumonisins, and zearalenone are the major Fusarium mycotoxins that occur worldwide.

Occupational exposure to zeranol, an animal growth promoter. [PDF]

Occupational and Environmental Medicine, 1989
Zeranol (3,4,5,6,7,8,9,10,11,12-Decahydro-7,14,16-trihydroxy-3-methyl-1H-2 - benzoxacyclotetradecin-1-one) is a synthetic oestrogenic agent used as an animal growth promoter. The effects of occupational exposure to zeranol in 11 exposed workers from a pelletising plant and 14 nonexposed subjects were assessed.

Determination of 60 Food‐Borne Stimulant Drug Residues in Animal‐Derived Foods by Solid‐Phase Extraction Purification and Ultra‐High‐Performance Liquid Chromatography‐Quadrupole/Orbitrap High‐Resolution Mass Spectrometry

Journal of Food Quality, Volume 2024, Issue 1, 2024.
A method for the rapid screening and confirmation of 60 food‐borne stimulants in animal‐derived foods was developed using the ultra‐high‐performance liquid chromatography‐quadrupole/orbitrap high‐resolution mass spectrometry (UPLC‐Q/Orbitrap HRMS). After enzymatic hydrolysis at 37°C for 16 h, the samples were extracted with acetonitrile solution.
