bacteriological water quality effects of hydraulically dredging contaminated upper mississippi river bottom sediment. | bacteriological effects of hydraulically dredging polluted bottom sediment in the navigation channel of the upper mississippi river (river mile 827.5 [about 1,332 km] to 828.1 [about 1,333 km]) were investigated. bottom sediment in the dredging site contained high total coliform densities (about 6,800 most-probable-number total coliform index per g [dry weight] and 3,800 membrane filter total coliforms per g [dry weight]), and fecal coliforms comprised an average 32% of each total coliform count ... | 1980 | 7377776 |

salmonella rarely detected in mississippi coastal waters and sediment. | standards for the rapid detection of individual pathogens from environmental samples have not been developed, but in their absence, the use of molecular-based detection methods coupled with traditional microbiology techniques allows for rapid and accurate pathogen detection from environmental waters and sediment. the aim of this research was to combine the use of enrichment with pcr for detection of salmonella in mississippi coastal waters and sediment and observe if that presence correlated wit ... | 2010 | 20854457 |
state programs for pesticide residues in foods. | two u.s. data collection and dissemination programs, feedcon and foodcontam, are described. feedcon provides information on contamination levels in animal feeds of toxic chemical residues (pesticides, industrial chemicals, heavy metals, mycotoxins, natural plant toxins, salmonella, and therapeutic drug cross-contaminations). feedcon data are collected from approximately 40 state feed regulatory agencies, feed manufacturers, and related groups who subscribe ($100-$200 per year) to the program, wh ... | 1989 | 2745384 |
risk factors associated with detection of salmonella in broiler litter at the time of new flock placement. | in this study, we investigated risk factors associated with the probability to detect salmonella in samples of litter collected within 2 h prior to new flock placement in 76 grow-out houses on 38 conventional broiler farms located in the us states of mississippi, alabama and texas. we evaluated characteristics of location and layout of the farm; area adjacent to and surrounding the house; house construction; condition and type of equipment in the house; litter management and other production, sa ... | 2011 | 20202186 |
recovery of salmonella from bermudagrass exposed to simulated wastewater. | most confined swine (sus scrofa) feeding operations in the southeastern united states hold manure in lagoons and apply effluent on bermudagrass [cynodon dactylon (l.) pers.] as fertilizer. salmonella enterica subsp. enterica (ex kauffman and edwards) le minor and popoff, has been reported in mississippi lagoons, but levels and potential for contamination of bermudagrass were unknown. a laboratory method was developed to examine salmonella contamination of bermudagrass and levels of salmonella we ... | 2009 | 19141824 |
excess salmonellosis in women in the united states: 1968-2000. | we describe recent epidemiological changes in salmonellosis. linking 1968-2000 national salmonella surveillance system to census data, we calculated population-based age- and sex-stratified rates of non-urinary salmonellosis for the top 30 non-typhoidal serotypes. using 1996-1997, 1998-1999, and 2000-2001 population-based foodnet surveys, we compared reported diarrhoea, medical visits, and stool cultures. despite an overall female-to-male incidence rate ratio (fmrr) of 0.99, the sex-specific bur ... | 2008 | 17961280 |
