IntroductionSalmonella, an essential food-borne pathogen, causes illness worldwide [1]. It was confirmed that S. Infantis was the causative agent for salmonellosis in humans in some countries. It was also the third most frequently isolated serovar of Salmonella after S. Enteritidis and S. Typhimurium in 2003 [2,3]. According to reports from European countries in 2014, S. Infantis is the dominant Salmonella isolate found in broiler meat (35.9%) [4]. In the same year, S. Infantis was the most frequently reported Salmonella serovar found in fowl [5]. As a result of these studies in Europe, S. Infantis emerged as the fourth most prevalent serovar causing human salmonellosis reported by the countries of the European Union/European Economic Area (EU/EEA) [6]. In 2015, S. Infantis was isolated from broilers, pigs, and humans globally [7]. In 2015 and 2016, S. Typhimurium and S. Infantis reached the same level [8]. According to the scientific reports of the European Food Safety Authority and the European Centre for Disease Prevention and Control (EFSA and ECDC) published in 2016 and 2017, in total 4786 and 5079, respectively, foodborne outbreaks (including waterborne) were reported [4,8]. In 2017, Thailand, Spain, Turkey, and India were the most commonly reported travel destinations (13.8%, 8.3%, 8.2%, and 6.7%). When compared with the prior 2 years, a higher number of samples were reported for 'meat and meat products' . S. Infantis was mostly associated with broiler flocks and meat with contamination rates of 46% and 51%, respectively. Some EU member states (
