Assessment of the application of Good Manufacturing Practices (GMP) in some wheat mills in Sudan

The present study was conducted during the period from April to December 2018. The objectives of this work were to assess the application of Good Manufacturing Practice (GMP) in nine wheat mills in Khartoum State and one wheat mills in Elobeid - North Kordofan State. Ready questionnaire prepared by Primus Lab Checklist (2013) was used and data were categorized according to GMP system. Concerning the first part of general GMP, the result revealed that two wheat mills in Khartoum state adopted the general GMP system whereas eight wheat mills were not adopted it. Regarding pest control requirements the mills scores ranged (48-87) out of 95 degree, for storage area and packaging material the score was (33-55) out of 55 degree, only one wheat mills in Khartoum state scored full degree. Concerning the operational practice requirement, all mills scores ranged (80-133) out of 144 degree and for the employee practice requirement they gained (9-45) out of 64 degree. In case of the equipment, the score was (32-50) for all mills and (40%) of wheat mills in Khartoum scored full degree whereas for the equipment cleaning requirement they acquired (26-60) and (20%) of them that belong to Khartoum had full degree, for general cleaning they recorded (32-73) out of 83 degree and for building and ground requirement they obtained (77-102) out of 106 degree. The total degree of Good Manufacture Practice (GMP) varied from 346 to 641 compared to 642 degree. The result showed that the mean total score of Good Manufacturing Practices in all expellers in this study was 693.3 points (69.33%) the highest score recorded 855 points (85.5%) in M8 and the lowest score obtained 555 points (55.5%) in M2, M6 and M10, respectively out of 1000 points. These findings indicated that the M8 plant was categorized as very good, while M9 was standard, but the rests of wheat mills studied in present investigation were categorized as unsatisfactory.
