ABSTRACT
Six varieties of date palm (Phoenix dactylifera L.) namely Nabtet-Aly, Sakei, Succary, Rashody, Rothana and Menephy of the most widely grown in Al-Qassem region, Saudi Arabia were selected to survey the microflora present in these varieties and studied its susceptibility to support the production of aflatoxins. The total number of spores present in the fruits of these varieties were in descending order: Menephy> Succary> Rashody> Sakei> Nabtet-Aly=Rothana. The most abundant genus found on dates was Aspergillus. Also, similar degrees of microflora growth were found when fruits were inoculated for 5 and 10 days with either A. flavus or A. parasiticus. The date fruits of all the tested varieties were able to support the production of different forms of aflatoxin such as B1, B2, G1 and G2. The contents of aflatoxin G2 produced by either A. flavus or A. parasiticus were higher than the other forms. Menephy and Sakei varieties contained less levels of the total aflatoxins when inoculated with either A. flavus or A. parasiticus, respectively. It is suggested that care must be exercised to avoid the poor conditions during the storage of dates.
