Found 10 records similar to Food Microbiology - Targeted Surveys - 2016 - 2017 Parasites in Fresh Whole Mushrooms - Final Report
A targeted survey of 2,233 samples of leafy vegetables for parasites found 98.8% to be satisfactory. Samples were analyzed for Cyclospora cayetanensis, Cryptosporidium spp., Toxoplasma gondii, and Giardia spp. Two samples contained parasite DNA of Cryptosporidium spp. and three samples contained Toxoplasma gondii DNA.
A targeted survey on bacterial pathogens in fresh leafy vegetables analyzed 5,508 samples for Salmonella, Shigella, non-O157 Verotoxigenic Escherichia coli (non-O157 VTEC), Verotoxigenic Escherichia coli O157 (E. coli O157), and generic Escherichia coli (E. coli). No Salmonella, Shigella, and E. coli O157 were found in any of the samples. Non-O157 VTEC was found in 1 sample and elevated levels of generic E. coli were found in 25 samples. The CFIA conducted appropriate follow-up activities resulting in facility inspections and/or additional sampling.A targeted survey analysed 483 samples of fresh mushrooms for the presence of deoxyribonucleic acid (DNA) from the following enteric parasites of concern: Cyclospora cayetanensis, Cryptosporidium species, Toxoplasma gondii, and Giardia species.
A targeted survey on parasites in imported whole fresh sugar snap and snow peas analyzed 932 samples for Cyclospora cayetanensis (C. cayentanensis), Cryptosporidium species (spp.) and Toxoplasma gondii (T. gondii). Of the 932 samples, 489 were also tested for Giardia spp. All samples were found to be free of parasites.

A targeted survey analyzed 1,828 samples of unpasteurized juices and high pressure processed juices for bacterial pathogens and indicators, viruses and parasites. An elevated level of generic Escherichia coli was found in one sample. All other samples were found to be free of bacterial pathogens, viruses, and parasites. The CFIA conducted appropriate follow-up activities.
This airborne or shipborne geophysical survey recorded the following parameters: Total Field Magnetic. The flight line spacing is 483 m. The survey was flown between 1962-05-01 and 1962-10-31. The data were Digitized from contour maps. Platform: Fixed-wing.
The study examines the parasite communities in Athabasca River Trout-perch (Percopsis omiscomaycus) at five sites along the main stem of the Athabasca River to explore whether any observed changes in parasite abundance or community structure might correlate with small-scale variations in water chemistry, sediment characteristics, water and sediment pollution, larger-scale landscape use patterns, distance among sites, and upstream-downstream gradients.
This dataset shows the locations of westslope cutthroat trout of non-stocked pure strain populations with average DNA purity ≥ 0.99%. This species is listed as threatened under the Species at Risk Act.
Number of deaths caused by certain infectious and parasitic diseases, by age group and sex, 2000 to most recent year.
The Richelieu River, Quebec, is a highly-regulated waterway subject to numerous anthropogenic influences from municipal effluents and agricultural activities. Parasite communities in 234 spottail shiners (Notropis hudsonius) were examined from 4 localities in late spring 2003 and 2004. Parasite component community similarity among localities could not be directly linked to available upstream water quality measurements or anthropogenic activity and was best explained by precipitation. This study suggests that fish parasite species composition and richness in the Richelieu River are influenced by environmental parameters which in turn ultimately are driven by a combination of climatic conditions and anthropogenic activities in the watershed.
