“…Additionally, multi-drug resistance was also higher for isolates from beef compared to isolates from vegetables (P ¼ 0.0259). These results differ from those obtained by other authors such as Sayah et al (2005) or Knezevic and Petrovic (2008) who obtained higher multidrug-resistance for E. coli isolated from pigs than for E. coli isolated from poultry and cattle. Multiresistant strains could have been originated as the result of co-selection of resistance determinants, because exposing a bacterial population to one antimicrobial agent may result in resistance to other agents without any additional exposure (Sayah et al, 2005).…”

“…Interestingly, the resistance of isolates was remarkably higher for older compounds, with the exception of gentamicin, which is a relatively old compound that has had little use in animals. In agreement with the findings reported in other countries (Bywater et al, 2004;Knezevic & Petrovic, 2008;Miranda et al, 2008a), resistance to this antimicrobial of animal-origin strains is rare. …”

“…During recent years, in addition to official surveillance and antimicrobial monitoring programmes (CI-PARS, 2006;DANMAP, 2006;MARAN, 2005;NARMS, 2007;SVARM, 2005;VAV Network, 2005), some studies have reported the antimicrobial resistance of E. coli isolated from meat samples and food-producing animals (Bywater et al, 2004;Guerra et al, 2003;Kijima-Tanaka et al, 2003;Knezevic & Petrovic, 2008;Miranda et al, 2008a;Sa´enz et al, 2001; Van den Bogaard et al, 2001). However, these works involved samples taken directly from live or recently slaughtered animals, and do not take into consideration the contamination of foods during subsequent steps in the food chain.…”

“…Monitoring the veterinary use of antimicrobial agents in animals destined for human consumption is considered as a risk-management option to prevent the development and spread of antimicrobial resistance in microorganisms present in food-producing animals (Vose et al, 2001 (Knezevic & Petrovic, 2008). When compared with the other microorganisms found mostly in foods, Escherichia coli has been a very useful biomarker for evaluating the development of antimicrobial resistance (Von Baum & Marre, 2005).…”

The presence of Escherichia coli in foods taken from the grocery stores and the supermarkets in Hidalgo State (Mexico) was determined for 73 samples of poultry meat, 60 samples of pork, 86 samples of beef, and 66 samples of vegetables. A total of 352 E. coli strains were isolated, identified, and analyzed by an agar disk diffusion assay for their resistance to 10 antimicrobials. Poultry meat and vegetables taken from groceries showed significantly higher counts (P ¼ 0.0002 and P ¼ 0.0461, respectively) when compared with the samples taken from supermarkets. Compared with the isolates recovered from other foods, E. coli isolated from chicken meat had higher levels of antimicrobial resistance against all antimicrobials tested, with the exceptions of nitrofurantoin resistance of isolates from pork and streptomycin resistance in isolates from pork and beef. In addition, the E. coli isolates from samples taken from the groceries showed higher resistance rates than the isolates from samples taken from the supermarkets for the cases of pork isolates resistance to ampicillin (P ¼ 0.0497), chloramphenicol (P ¼ 0.0075), doxycycline (P ¼ 0.002), and streptomycin (P ¼ 0.0094) and beef isolates resistance against ampicillin (P ¼ 0.0048), streptomycin (P ¼ 0.002), and sulfisoxazole (P ¼ 0.003). The present study revealed that the observed resistance rates correlated well with those reported in the national surveillance programmes of developed countries, with the exception of isolates from chicken meat, which have higher resistance rates. Also, from a microbiological safety point of view, samples taken from supermarkets were in a much better conditions than those obtained from the groceries.Keywords: E. coli; antimicrobial; food-borne; resistance; Me´xico La presencia de Escherichia coli fue investigada en 73 muestras de carne de pollo, 60 muestras de carne de cerdo, 86 muestras de carne de vacuno y 66 muestras de alimentos vegetales muestreados en pequen˜os ultramarinos y supermercados en el estado de Hidalgo (Me´xico).

“…Many studies of the presence of antimicrobial resistance in several animal-producing environments such as sheep, cattle, swine, or broiler farms have been conducted (13)(14)(15)(16)(17)(18)(19)(20)(21). However, only a few publications are available about studies of whether vegetables or the environment where they are produced can act as a carrier or reservoir of antimicrobial resistance (22,23).…”

cFresh produce is known to carry nonpathogenic epiphytic microorganisms. During agricultural production and harvesting, leafy greens can become contaminated with antibiotic-resistant pathogens or commensals from animal and human sources. As lettuce does not undergo any inactivation or preservation treatment during processing, consumers may be exposed directly to all of the (resistant) bacteria present. In this study, we investigated whether lettuce or its production environment (irrigation water, soil) is able to act as a vector or reservoir of antimicrobial-resistant Escherichia coli. Over a 1-year period, eight lettuce farms were visited multiple times and 738 samples, including lettuce seedlings (leaves and soil), soil, irrigation water, and lettuce leaves were collected. From these samples, 473 isolates of Escherichia coli were obtained and tested for resistance to 14 antimicrobials. Fiftyfour isolates (11.4%) were resistant to one or more antimicrobials. The highest resistance rate was observed for ampicillin (7%), followed by cephalothin, amoxicillin-clavulanic acid, tetracycline, trimethoprim, and streptomycin, with resistance rates between 4.4 and 3.6%. No resistance to amikacin, ciprofloxacin, gentamicin, or kanamycin was observed. One isolate was resistant to cefotaxime. Among the multiresistant isolates (n ‫؍‬ 37), ampicillin and cephalothin showed the highest resistance rates, at 76 and 52%, respectively. E. coli isolates from lettuce showed higher resistance rates than E. coli isolates obtained from soil or irrigation water samples. When the presence of resistance in E. coli isolates from lettuce production sites and their resistance patterns were compared with the profiles of animal-derived E. coli strains, they were found to be the most comparable with what is found in the cattle reservoir. This may suggest that cattle are a potential reservoir of antimicrobial-resistant E. coli strains in plant primary production.
