“…These three genus were found in 87.42 of the samples analyzed. These results are in agreement with that reported by others (Abou-Arab et al, 1999;Aziz et al, 1998;Halt, 1998;Mandeel, 2005 andRoy et al, 1988). Other fungal genera isolated, such as Cladosporium, Curvularia, Fusarium and Helminthosporium, have been reported previously to be the most common resident fungi isolated from medicinal plants under filed conditions (Aziz et al, 1998).…”

This investigation was designed to evaluate the fungal load of five randomly selected plant samples. A total of 150 dry samples of Basil, Mint, Marjoram, Chamomile and Fennel were collected from some markets in Egypt. All samples were analyzed among moulds and yeasts, also the samples were analysis for mycotoxins status. Fungi were found in most of the collected samples. The highest count of moulds presents in Mint, Basil, Marjoram, Fennel, and Chamomile in descending order, respectively, while the highest count of yeasts was presented in Chamomile, Mint, Fennel, Basil, and Marjoram , respectively. Aspergillus spp. Fusarium spp., Penicillium spp. Mucor spp. and Humicola spp.were more frequently detected. Total aflatoxins, ochratoxin A, zearalenone, and fumonisins B1 and B2 were determined in all samples.The genus Aspergillus was the most dominant fungal, where it was recovered( 3761 isolates )followed by Fusarium (1023 isolates) while genus of Penicillium was recovered( 687 isolates). These three species were found in 87.42 5% of the samples. Aspergillus . flavus exhibited total aflatoxins of 3220 ppb. The direct use of the medicinal plants may be high risk due to their high contents of many species of moulds.The effect of preparing method of the selected plants to drink was studied. Adding of sugar or honey as sweeters to medicinal plant drinks showed no effect on the fungal load status. No inhibition zones were seen against the investigated fungi.

They have also been found in medicinal herbs (Roy et al, 1988;Abeywickrama and Bean, 1991;Reif and Metzger, 1995;Han et al, 2010) that are not fully dried or stored improperly (e.g. at high temperature and humidity; Ip and Che, 2006).…”

This simple and accurate method effectively eliminates false positive detection and can be used to determine the AFs in medicinal herbs to control product quality. We found that in the 174 samples tested, 27 were contaminated with AFs. The incidences of AFB1, AFB2, AFG1 and AFG2 in the samples tested were 15.52%, 14.37%, 6.32% and 2.30%, respectively. We proposed 10 µg/kg total AFs and 5 µg/kg AFB1 as the reasonable maximum limits (ML) in medicinal herbs, and there are 10 samples (5.71% occurrence) in our test that exceeded this proposed limit.

“…The potential of producing aflatoxins (AFB1) by some 20 strains of Aspergillus flavus contaminating raw drugs has been reported by Chourasia (1990) who reported levels ranging between 0.09 and 0.88 μg/mL of the culture filtrate. Roy and others (1988) analyzed common drug plants to detect aflatoxin contamination. Out of 15 samples analyzed, 14 were positive for aflatoxins ranging between 0.09 μg/g in Acacia catechu and 1.20 μg/g in Piper nigrum .…”

Disease outbreaks due to the consumption of contaminated food and feedstuff are a recurring problem worldwide. The major factor contributing to contamination are microorganisms, especially fungi, which produce low-molecular-weight compounds as secondary metabolites, with confirmed toxic properties referred to as mycotoxins. Several mycotoxins reported to date are cosmopolitan in distribution and incur severe health-associated risks (including cancer and neurological disorders). Hence, creating awareness among consumers, as well as developing new methods for detection and inactivation is of great importance for food safety. In this review, the focus is on the occurrence of various types of mycotoxins in food and feed associated with risks to humans and livestock, as well as legislation put forth by various authorities, and on presently practiced detoxification methods. Brief descriptions on recent developments in mycotoxin detection methodology are also inlcuded. This review is meant to be informative not only for health-conscious consumers but also for experts in the field to pave the way for future research to fill the existing gaps in our knowledge with regard to mycotoxins and food safety.
