| microbiological quality of fresh produce obtained from retail stores on the eastern shore of maryland, united states of america. | the aim of this study was to investigate the microbiological quality of six types of fresh produce obtained from three retail stores located on the eastern shore of maryland, usa. a total of 414 samples representing basil, cilantro, lettuce, scallion, spinach, and parsley were analyzed for total aerobic bacteria (apc), total coliforms, escherichia coli, and three pathogenic bacteria (e. coli o157:h7, listeria monocytogenes, and salmonella), using standard methods. presumptive pathogenic isolates ... | 2016 | 26919815 |
| isolation and characterization of escherichia coli recovered from maryland apple cider and the cider production environment. | contaminated apple cider has been implicated in several escherichia coli o157:h7 outbreaks. in an attempt to investigate sources and modes of entry of e. coli into apple cider, samples of fresh apple, pomace, and cider and equipment and mill floor swabs were analyzed for standard plate counts (spc), total coliforms (tc), fecal coliforms (fc), and e. coli. e. coli was isolated from 14 (33%) of 42 samples of bottled fresh cider, from food equipment in 6 (67%) of 9 mills, and from apples, pomace, o ... | 2003 | 14672219 |
| use of hazard analysis critical control point and alternative treatments in the production of apple cider. | the purpose of this study was to evaluate the practices of maryland cider producers and determine whether implementing hazard analysis critical control point (haccp) would reduce the microbial contamination of cider. cider producers (n = 11) were surveyed to determine existing manufacturing practices and sanitation. a training program was then conducted to inform operators of safety issues, including contamination with escherichia coli o157:h7, and teach haccp concepts and principles, sanitation ... | 1999 | 10419272 |
