Description

Zearalenone is a natural estrogen, a mycotoxin from resorcylic acid lactone group.

Zearalenone is a non-steroidal estrogenic mycotoxin produced by several Fusarium spp. It has been implicated in numerous mycotoxicoses in farm animals, especially in pigs. Zearalenone is heat-stable and is found worldwide in a number of cereal crops, such as maize, barley, oats, wheat, rice, and sorghum (Kuiper-Goodman et al., 1987; Tanaka et al., 1988a) and also in bread (Aziz et al., 1997). Zearalenone was shown to be produced on corn by Fusarium isolates from Australia, Europe, and North America (Vesonder et al., 1991) and in New Zealand (diMenna et al., 1997), the Philippines, Thailand, and Indonesia (Yamashita et al., 1995). The occurrence of zearalenone in food and feed was also demonstrated in South America (Dalcero et al., 1997; Molto et al., 1997), Africa (Doko et al., 1996), China and the former USSR (Ueno et al., 1986). Fusarium isolates from bananas can also produce zearalenone

Sexual reproduction in Fusarium is regulated by the fungal sex hormone zearalenone, which is known to be synthesized only by species of Gibberella zeae (Fusarium roseum)

Storage, handling

Store in a freezer upon arrival, at -10°C to -25°C

Keep the lid tightly closed.

Avoid exposing to strong direct light.

Other vendors may recommend higher temperatures for storage.
