“…The extensive use or misuse of antimicrobial agents, not only as treatment in humans and veterinary medicine but also as growthpromoting substances in livestock production, has greatly promoted the appearance of antimicrobial-resistant bacteria (Araque, 2009;Gousia, Economou, Sakkas, Leveidiotou, & Papadopoulou, 2011;Hur et al, 2010;Singh et al, 2010) which has become a major public health issue. Recently, the European Union (EU) initiated several actions including the removal of all antimicrobials used as growth-promoting substances in the livestock industry (Regulation EC 1831/2003) (García-Feliz et al, 2008) in an effort to decrease the appearance of antimicrobial-resistant bacteria.…”

“…In another study in Spain among isolates obtained through the Spanish Veterinary-Antimicrobial-Resistance-Surveillance Network (VAV), 4 of 556 (0.7%) Salmonella organisms obtained from faecal samples of healthy food animals (pigs and poultry) at the slaughterhouse level were ESBL producers, representing 0.2% in the case of pigs and 2.5% of all isolates in the case of poultry (Riano et al, 2006). ESBL-producing Salmonella prevalences of 0.5-0.6% were detected in Italy, Korea and Japan Hur et al, 2010;Matsumoto et al, 2007).…”

The potential contribution of food-producing animals or foods to public health risks by ESBL and/or AmpCproducing bacteria is related to specific plasmid-mediated ESBL and/or AmpC genes encoded by a number of organisms. The predominant ESBL families encountered are CTX-M, TEM, and SHV; the predominant AmpCfamily is CMY. The most common genes associated with this resistance in animals are bla CTX-M-1 (the most commonly identified ESBL), and bla CTX-M-14 , followed by bla and bla Among the genes encoding AmpC-type β-lactamases, bla CMY-2 is the most common.The bacterial species most commonly identified with these genes are Escherichia coli and non-typhoidal Salmonella. ESBL/AmpC transmission is mainly driven by integrons, insertion sequences, transposons and plasmids, some of which are homologous in isolates from both food-production animals and humans. Cefotaxime is used as the drug of choice for optimum detection of bla ESBL and/or bla AmpC genes. The preferred method for isolation of ESBL-and/or AmpC-producers is screening on selective agar preceded by selective enrichment in a broth.The establishment of risk factors for occurrence of ESBL/AmpC-producing bacteria is particularly complicated by the data unavailability or lack of its accuracy. The use of antimicrobials is a risk factor for the selection and spread of resistant clones, resistance genes and plasmids. Since most ESBL-and AmpC-producing strains carry additional resistances to other commonly-used veterinary drugs, generic antimicrobial use is a risk factor for ESBL/AmpC and it is not restricted specifically to the use of cephalosporins. An additional risk factor is extensive trade of animals in EU MS. There are no data on the comparative efficiency of individual control options in reducing public health risks caused by ESBL and/or AmpC-producing bacteria related to food-producing animals. Prioritisation is complex, but it is considered that a highly effective control option would be to stop all uses of cephalosporins/systemically active 3 rd /4 th generation cephalosporins, or to restrict their use (use only allowed under specific circumstances). As co-resistance is an important issue, it is also of high priority to decrease the total antimicrobial use in animal production in the EU. KEY WORDSResistance, ESBLs, AmpC, occurrence, transmission, control options, public health microbiology. SUMMARYFollowing a request from the European Commission, the Panel on Biological Hazards (BIOHAZ) was asked to deliver a Scientific Opinion on the public health risks of bacterial strains producing extended-spectrum beta (β)-lactamases (ESBL) and/or AmpC β-lactamases (AmpC) in food and foodproducing animals. In particular, the Panel was asked: (i) to propose a definition of the ESBL-and/or AmpC-producing bacterial strains and genes relevant for public health and linked to food-producing animals or food borne transmission; (ii) to review the information on the epidemiology of acquired resistance to broad spectrum cephalosporins including the genes coding for ...

“…It causes great number of illness and substantial economic losses in both developing and developed countries. It is more often associated with foodborne Salmonellosis (Akbar and Anal 2013;Fernandez et al 2012;Hur et al 2011), and human gastroenteritis (Skov et al 2007). Consumption of animal food products are thought to be the major cause of the Salmonella outbreaks (Thai et al 2012).…”

A study was conducted to evaluate the risk of Salmonella contamination and its survival at different stages in chill ready-to-eat poultry meat products chain. Samples (n= 181) were collected and examined for the presence of Salmonella species. The bacteria were initially identified against polyvalent antisera "O" and "H", followed by confirmation with 16 s rDNA. The single Salmonella, isolate from the tested food samples showed 99.8 % phylogenetic similarity with Salmonella enterica. It was further evaluated for antibiotic sensitivity pattern and found resistant to four antibiotics including ampicillin, chloramphenicol, tetracycline and nalidixic acid. Salmonella associated with ready-to-eat poultry meat products were found active at storage temperature ≥4°C in a challenge study. It was revealed that shape and weight of the meat pieces have direct influence on the reduction of pathogens during microwave heating. The 30 and 60 s microwaving (with radiation power fixed at 900 W) was found ineffective for the elimination of target bacteria (10 6 -10 7 CFU/g) in meat pieces with weight ≥90 g. Salmonella enterica was able to survive in simulated gastric fluid. The storage temperature and microwaving were found critical point for the transfer of pathogens through ready-to-eat poultry meat products to consumer in chill ready-to-eat poultry meat chain.
