“…Addition of dichlorvos to culture media of two strains of Alternaria altemata and application of dichlorvos to sunflower seeds showed marked decreases in alternariol, alternariol monomethyl ether, and tenuazonic acid levels (20). In a different study, sumi oil also reduced levels of alternariol and alternariol monomethyl ether when added to cultures of two strains of Alternaria altemata isolated from decayed fruits (25).…”

“…Iprodione inhibited aflatoxin production from a strain of Aspergillus parasiticus grown in culture (23), while the use of propionic acid (as ammonium propionate) sprayed on moist unshelled peanuts effectively reduced aflatoxin levels (24). The fungicide cuprosan (a mixture of manganese and zinc ethylenebisdithiocarbamates and copper oxychloride), when applied to two strains of Alternaria altemata isolated from decayed fruits, inhibited synthesis of alternariol and its monomethyl ether (25).…”

While the potential health risks from pesticide residues generate significant public, legislative, and regulatory concern, it is possible that agricultural pesticide use may, on occasion, influence dietary risks. It has been proposed that pesticide use may reduce the risks associated with naturally-occurring toxins of plants and fungi by reducing the pest pressures which may stress plants into producing their own toxins or by controlling the fungi responsible for mycotoxin production. Very little direct research has been published investigating such pesticide/natural toxin relationships, however; the limited results have indicated that pesticide use may increase or decrease naturally -occurring toxin levels. Current regulatory programs to examine such relationships are burdened by statutory limitations and jurisdictional issues. Present U.S. pesticide regulations allow only very limited consideration of benefits such as decreased risks from naturally -occurring toxins, and separate federal agencies control the regulation of pesticides and the regulation of naturally-occurring food toxins.Pesticide residues and their potential human health effects continue to receive considerable public, legislative, and regulatory attention while media accounts of this controversial topic remain frequent. The passage of the Food Quality Protection Act (FQPA) of 1996 (7) has presented tremendous challenges to pesticide regulators as they strive to more effectively perform risk assessments that consider factors such as cumulative and aggregate exposure and the special exposure and susceptibility issues of sub-populations (i.e. infants and children). Enforcement of FQPA may result in a significant number of regulatory actions limiting the uses of many pesticides, particularly those which belong to families of chemicals that share common toxicological mechanisms of action such as the organophosphate insecticides, the carbamate insecticides, and the triazine herbicides.
