This study aimed to synthesize zinc oxide nanoparticles (ZnONPs) by the green method using Henna ( L.) leaf Lawsonia inermis extract as a reducing and covering agent. The composition of the nanoparticles was confirmed by the color changes from dark brown to light brown after adding the Zn (NO) solution, and upon increasing the concentration of Zn (NO), an increase in the intensity of the light brown color

The present study was performed to assess the presence of Enterobacteriaceae in raw meat in Iraq using cultivation and the VITEK®2 compact system. A total of 20 chicken raw meat samples were randomly purchased from butchers and local meat retailers located in Najaf, Iraq. Five bacterial isolates were recovered from these samples. Proteus mirables (70%) was found to be the most abundant, followed by Enterobacter cloacae complex (15%), Pseudomonas aeruginosa and Salmonella enterica subsp diarizonae (10%), and Enterobacter aerogenes (5%). It is worth noting that the presence of Salmonella enterica ssp diarizonae in local chicken meat represents the first record of such an isolate in Iraq. Moreover, the presence of several Enterobacteriaceae in locally produced retail raw chicken meat raises concerns about the possibility of cross-contamination with other food items. also enhances the danger of human infection from eating raw or undercooked meat. To lessen the danger of infection, veterinarians and public health authorities must coordinate and take synchronized action.

Several natural compounds have recently been discovered to be effective in the management of numerous pathogenic microorganisms. Kojic acid is an example of such a compound (KA). It is a byproduct of the fungal fermentation process that is commonly used in the production of food and cosmetics. The well diffusion method was used to determine the antifungal activity of various KA concentrations, viz., 20, 25, and 30 mg/μl, against the bread mold. On the seventh day of incubation, an evaluation was performed. The factors detected were the inhibition of bread mold growth with an enumerated size of diameter mycelial growth. The study's findings showed that KA inhibited mycelial growth, with the highest inhibition found at 25 and 30 mg/μl concentrations, with no significant difference between the two treatments. Based on these findings, the best concentration (30 mg/μl) was tested further using the well diffusion …
