“…However, the range of microbial load in the present study was broader than previous studies in Yemeni and Saudi Arabia green coffee (0.6 Â 104 to 5.5 Â 104 CFU) and (19 Â 10 to 18 Â 104 CFU), respectively. 32,33 The reasons for the difference in counts could be due to only dried beans were involved in previous studies while in this study in addition to dried beans, coffee fruits, fermented beans, and washed beans were included.…”

Coffee workers respiratory health problems, found to be associated with dust exposure in the coffee factories, but the content of the dust is not well known. A cross-sectional survey was conducted to assess the microbial contamination of coffee in dry and wet coffee process, from four farms in two regions of Ethiopia. A total of 36 samples of coffee were collected for laboratory investigation. The microbial load in the dry process ranged from 6.9 Â 10 2 to 7.2 Â 10 5 colony forming units (CFU)/mL while the microbial load in wet process ranged from 2.5 Â 10 2 to 4.6 Â 10 5 CFU/mL. The results indicate the presence of gram negative bacteria in dried and stored beans from both the wet and dry process. During further coffee processing possible release of endotoxin from coffee contaminated by gram negative bacteria might affect coffee workers respiratory health. Further studies are required to assess the relation between bacterial contamination of coffee and endotoxin level in coffee factories.

“…Another study in Egypt investigated resistance in ten Salmonella strains isolated from poultry meat against amoxicillin-clavulanic acid (90%), trimethoprim-sulfamethoxazole (80%) and streptomycin, ampicillin-sulbactam, nalidixic acid, and gentamycin at 70% each [68]. In Morocco [58], 104 S. Enterica isolates from food origin were found resistant to tetracycline (21%), ampicillin (13%), amoxicillinclavulanic acid (9%), streptomycin (7%), chloramphenicol (4%) and nalidixic acid (3.8%). Because NTS is associated with increased morbidity and mortality, the determination of antimicrobial resistance profiles should be regarded as a vital part of NTS surveillance in food safety and public health laboratories in Arab countries.…”

Foodborne infections caused by bacterial pathogens are a common cause of human illness in the Middle East, with a substantial burden of economic loss and public health consequences. This review aims at elucidating recent literature on the prevalence of Non-Typhoidal Salmonella (NTS), Campylobacter and Listeria monocytogens in the food chain in the Arab countries, and to consolidate available evidence on the public health burden and the status of antimicrobial resistance (AMR) among the concerned three pathogens. The reviewed evidence points to a scarcity of understanding of the magnitude of NTS in the food chain in the Arab countries. Additionally, not much work has been done at the molecular characterization level to address the source-attribution of NTS in the Arab World. Very few surveys have been done on Campylobacter in the food chain in the Gulf Cooperation Council (GCC) countries. There is a gap in quantitative (counts/numbers) surveillance efforts for Campylobacter in the chicken meat supply across all Arab countries, despite the availability of some qualitative (presence/absence) surveillance data. While there are several reports on L. monocytogenes in animal-sourced foods, notably in North African Arab countries, fewer are published on L. monocytogenes in plant-sourced foods. Information on the L. monocytogenes serotypes and strain diversity circulating in the Arab region is widely lacking. Antibiotic resistance in the three pathogens is not fully understood across the Arab region, despite some reports indicating varying trends at the human–food interface. The literature evidence presented in this review stresses that Salmonella, Campylobacter and L. monocytogenes continue to challenge food safety and public health in the Arab countries.

“…Then, the volume was adjusted to 2.00 mL with a mixture of 0.0025 mol mL −1 HTAB and ammonia buffer (0.020 mol mL −1 , pH = 9.3). For test samples, the interferences considered were ZEN and STE because these mycotoxins can be found together with OTA in coffee and tea samples [31][32][33][34]. Accordingly, test samples were prepared in a similar way to validation solutions but with the addition of ZEN and STE solutions before evaporating the solvent and reconstituting the solution with a 2.00 mL mixture of HTAB and ammonia buffer.…”
