“…It is well established on poultry farms with a tendency of clonal spread of the multidrug resistance phenotype. Clonal spread of Salmonella Infantis in poultry and poultry meat was reported in Japan (Shahada et al, 2006), Hungary (Nógrády et al, 2007), Israel (Gal-Mor et al, 2010), Italy (Dionisi et al, 2011), Germany (Hauser et al, 2012), Serbia (Rašeta et al, 2014;Velhner et al, 2014) but also in humans in Argentina (Merino et al, 2003) and Brazil (Fonseca et al, 2006). All these clonal strains were resistant to three or more antimicrobials except for Serbia, where the predominant resistance phenotype was nalidixic acid (NAL) / tetracycline (TET), while an approximate 30% of the isolates was showing resistance to ciprofloxacin (CIP), with the minimal inhibitory concentration (MIC) of > 1mg/L (Velhner et al, 2014).…”

ABSTRACT. The knowledge about virulence mechanisms, resistance to antimicrobial agents and the biofilm formation ability of Salmonella spp. in poultry industry has been expanded over the years. However, in spite of the research efforts and significant investments to improve management systems in poultry industry, it has become evident that none of the methods applied in all stages of food production chain are 100% effective in eliminating Salmonella spp. Different serovars are manifesting different mechanisms of invasiveness which depend on their ability to invade lower zones of the lamina propria, their ability to gain accesses to parenchymatous organs and survive in macrophages. The ubiquitous nature of Salmonella spp. due to their adaptation to animal and plant hosts, as well as their survival in hostile environments and their enhanced capacity to produce biofilms, contribute to a long lasting contamination of the environment, feed and animals. The emergency and spread of antimicrobial resistances in Salmonella spp. raise additional concerns.

“…Infantis, in fact, is a cause of human salmonellosis in several countries and represents the third most frequent serotype isolated in Europe (1.1%) after Salmonella Enteritidis and S. Typhimurium (Dionisi et al, 2011). Moreover, in recent years S. Infantis has represented the third Salmonella serovar amongst environmental samples in Italy (Dionisi et al, 2011). In the European Union, an international surveillance network, designated Enter-net, has been active since 1994.…”

“…Infantis was also reported in high numbers from G. gallus in Italy, and a link and/or common source of the infection in chickens and turkeys in Italy is a possibility (Dionisi et al, 2011).…”

VTEC was reported from food and animals. A total of 5,251 food-borne outbreaks, including waterborne outbreaks, were reported. Most food-borne outbreaks were caused by viruses, followed by Salmonella, bacterial toxins and Campylobacter and with unknown causative agent in 29.1% of all outbreaks. Important food vehicles in strong-evidence food-borne outbreaks were 'eggs and egg products', followed by 'mixed food' and 'crustaceans, shellfish, molluscs and products thereof'. The report further summarises trends and sources along the food chain of tuberculosis due to Mycobacterium bovis, Brucella, Trichinella, Echinococcus, Toxoplasma, rabies, Coxiella burnetii
