OBJECTIVE The objective of this study was to determine the risk of acquiring disease from popular Sierra Nevada wilderness area lakes and streams. This study examines the relative risk factors for harmful waterborne microorganisms using coliforms as an indicator. METHODS Water was collected in the backcountry Yosemite and Kings Canyon National Parks and neighboring wilderness areas. A total o...

Bacterial counts from paired broiler carcass halves were examined for relationships between numbers and kinds of bacteria that might indicate fecal contamination. Broiler carcasses removed from a commercial processing plant just before chilling were split aseptically along the midline, and each side was rinsed in 400 mL of phosphate buffered saline for 1 min with either mechanical or hand shaki...

The present study assessed the microbiological quality of pre-cooked and refrigerated seafood marketed in Santa Catarina Island, Brazil. Forty-eight samples of crabs, mussels, shrimp and clams were purchased at fish markets in Santa Catarina Island from June to September 2008. Microbiological analysis were conducted for total counts of psychrotrophic, coliforms at 45 °C, Enterococcus spp., Esch...

Minimally processed vegetables go through various steps during their preparation, with many modifications to their natural structure. However, they must maintain the same quality as the fresh produce. The aim of the present study was to quantify mesophilic and psychrotrophic microorganisms and total and faecal coliforms, and to assess the presence of Escherichia coli, parasites, and dirt materi...

A bacteriological survey was conducted of untreated, individual groundwater supplies in Preston County, W.Va. Nearly 60% of the water supplies contained total coliforms in excess of the U.S. Environmental Protection Agency maximum contaminant level of 1 CFU/100 ml. Approximately one-third of the water systems contained fecal coliforms and/or fecal streptococci. Acinetobacter spp. were detected ...

background and purpose: most traditional tea shop owners use a bowl to wash tea cups in sari city (north of iran). there are more than 140 traditional tea shops in the city. unfortunately most people drinking at these shops as well as health authorities do not pay attention to the health criteria of the shop. the objective of this study was to examin the tea cups washing water of traditional te...

Our objectives were to evaluate the effects of transportation and lairage on fecal shedding of Escherichia coli O157 (E. coli O157), total Escherichia coli, and total coliforms in feedlot cattle, and the relationships between E. coli O157 prevalence and total E. coli population. The study was a randomized complete block design with a split-plot including 2 treatments: a nontransported group, wh...

in this essay, the heavy metal resistance patterns of bacterial strains isolated from industrial wastewater, domestic wastewater and various parts of the wastewater treatment system of arak city have been studied. 28 intestinal bacterial strains were screened and identified as klebsiella, escherichia coli, citrobacter and enterobacter species biochemical methods. the minimum inhibitory concentr...

background: swimming is often recommended because of its potentially beneficial effects on the joints and on people’s general sense of well-being . swimming is a great way to relax and beat the summer heat. the dumping of urban and industrial waste waters into the sea, with their high level of pathogens and other polluting agents, raises concern about its consequences for both swimmers’ health ...
