Detection of microorganisms and afla toxins (B1) in local wheat grains and local flour produced in Iraq

Abstract

It can cause scattered dust and usually loaded with various germs that adversely affect the health of silos workersin silos. The main objective of the study is to measure microbial contamination. (bacterial, fungal, mycotoxins), which are widely prevalent in Iraqi silos and mills and negatively It affects the health of silos workers in particular and the general health of the community. The study included 40 samples of wheat grains and 40 samples of wheat flour, which were randomly collected for the winter seasons from 4 silos in Baghdad, silo Maysan and siloAL- Basra, and silo Erbil and silo Kirkuk during December and January 2022. The results indicated that the most isolated types of wheat and wheat flour are pathological spores in addition to the presence of a percentage of microbial toxins, and the chemical analysis with HPLC during the winter season showed the presence of toxic mycotoxin contamination for a number of silos, and the khan was about (76.6 ppb) by 12.5%, while the silos (cycle, coronary) were about 37.5%, with statistically significant differences (p. ≤ 0.05). The results of the statistical analysis indicated that there were statistically Statistically significant differences (p≤0.05) were recorded for wheat and flour in (temperature and humidity associated with storage,) and most of them samples contained more Coliforms and Mold than the permissible limit, while some of the samples contained an allowable percentage of mycotoxins.
