Abstract
The safety of meat has been at the forefront of societal concerns in recent years, and indications exist that challenges to meat safety will continue in the future. Major meat safety issues and related challenges include the need to control traditional and emerging pathogenic microorganisms, such as increased virulence and low infectious doses or resistance to antibiotics or food-related stresses. This study aimed to recognize microbial contamination and heavy metals content. Thirty-eight frozen and freshly prepared burger (local and imported) samples were collected from randomly selected supermarkets and fast-food restaurants in Jeddah. Yeasts/Molds had the highest count (204.3 CFU/mL) followed by total aerobic mesophiles (69.5 CFU/mL), total coliforms (16.2 CFU/mL) and Escherichia coli (10.0 CFU/mL). Salmonella species were positive in 39.5% of samples. Fresh burgers had more counts of TVC, total coliforms, Escherichia coli, and Bacillus cereus. Amoxicillin-clavulanate and Ampicillin had a high frequency of resistance in the studied sample. None of the studied samples had detectable traces of heavy metals' elements. This research provides valid data to protect consumers from different health risks related to burgers in Saudi Arabia.
