“…Rosiles (1978) detected 0.5 to 5 ppm of aflatoxin B, in maize silage in the upper, more aerated, layers of clamp silos and the basal layers of trench silos. Lindenfelser & Ciegler (1970) attempted to detoxify aflatoxin B, to the relatively non-toxin B,, in maize by ensilage. The concentration of aflatoxin B, was 6 gg/kg in maize silage contaminated with Aspergillus parasiticus.…”

“…Although treated pistachio samples showed a marked reduction in aflatoxin content, the treatment strongly discolored and darkened the shells and kernels. These effects could be due to high alkalinity of the solution (pH = 9) rather than the low concentration of the dissolved natrolite in the solution (Lindefelser and Ciegler 1970;Letutour and others 1983). Therefore, this effective method was considered impractical.…”

“…A variety of physical, chemical, and biological methods for removing aflatoxins from foodstuffs have been reported, but they are not applicable to foods (Lindefelser and Ciegler 1970;Letutour and others 1983;Klich and others 1995). A relatively new approach to the control of aflatoxins is the use of adsorptive materials that have the ability to bind and adsorb mycotoxins with high affinity (Ramos and others 1996).…”

Natrolite was used to explore a physical and safe method to decontaminate aflatoxin-containing pistachio lots. Pistachio nuts with low, medium, and high levels of aflatoxin were subjected to a washing process with a slurry of 5% natrolite. Using thin-layer chromatography and scanning, the aflatoxin contents of the samples were measured. Aflatoxins B 1 and B 2 were found in pistachio nuts. The majority of total aflatoxins was aflatoxin B 1 . Natrolite treatment resulted in a 38% to 100% reduction in aflatoxin B 1 , depending on the initial aflatoxin level. Although natrolite was demonstrated to be an effective candidate to reduce aflatoxin B 1 , its efficacy against aflatoxin B 2 was limited.

“…It was also possible that microflora in the silage fermentation would degrade the mycotoxin. Ariatoxin-contaminated, high-moisture corn was ensiled in detoxification attempts (80). The moldy corn did undergo a lactic fermentation, but insufficient acid was produced to form aflatoxin B2a from the B l present.…”

and Summary Low incidence and levels of aflatoxin were identified in corn of all grades grown in the Midwest in 1964, 1965, and 1967. Later surveys indicate that corn grown in southern regions is subject to invasion byAspergillus flavus and subsequent aflatoxin formation. This mycotoxin is formed either in the field or in storage. In the field, such factors as insect damage and weather conditions probably influence aflatoxin formation. In storage, temperatures must be above 25 C and moisture levels above 16% if toxin is to form. Aflatoxin formed in a hot spot in stored corn in the Midwest when temperatures rose early in the summer and when the grain became wet because of leaks in the storage building. Analytical methods to detect and determine aflatoxin fall into three categories: presumptive tests indicating the presence ofA. flavus and the possible occurrence of aflatoxin, rapid screening tests establishing the presence or absence of the toxin, and quantitative procedures determining toxin levels. Detoxification methods being studied include ammoniation and roasting. Ammoniated corn is being fed domestic animals to determine whether it has adverse effects and whether toxic compounds are transmitted in animal tissues.
