Journal ArticleDOI
Bacteria in drinking water sources of a First Nation reserve in Canada
Annemieke Farenhorst,Ru Li,Musarrat Jahan,Hein M. Tun,Ruidong Mi,Inoka Amarakoon,Ayush Kumar,Ehsan Khafipour +7 more
TL;DR: This study detected fecal bacteria at an alarmingly high frequency in drinking water sources in a fly-in First Nations community, most notably in buckets/drums of homes without running water where Escherichia coli levels ranged from 20 to 62,000CFU/100mL.
Journal ArticleDOI
Runoff Losses of Excreted Chlortetracycline, Sulfamethazine, and Tylosin from Surface-Applied and Soil-Incorporated Beef Cattle Feedlot Manure
Inoka Amarakoon,Francis Zvomuya,Allan J. Cessna,Dani Degenhardt,Francis J. Larney,Tim A. McAllister +5 more
TL;DR: Although the results confirm that cattle-excreted veterinary antimicrobials can be removed via surface runoff after field application, the magnitudes of chlortetracycline and sulfamethazine losses were reduced by soil incorporation of manure immediately after application.
Journal ArticleDOI
Dissipation of Antimicrobials in Feedlot Manure Compost after Oral Administration versus Fortification after Excretion.
Inoka Amarakoon,Francis Zvomuya,Srinivas Sura,Francis J. Larney,Allan J. Cessna,Shanwei Xu,Tim A. McAllister +6 more
TL;DR: This study examined the dissipation of antimicrobials excreted in manure versus those added directly to manure (fortified) and found that on average, 85 to 99% of the initial antimicrobial concentrations in manure were dissipated after 30 d of composting.
Journal ArticleDOI
Dissipation of antimicrobial resistance genes in compost originating from cattle manure after direct oral administration or post-excretion fortification of antimicrobials.
Shanwei Xu,Inoka Amarakoon,Rahat Zaheer,Alanna Smith,Srinivas Sura,George Wang,Tim Reuter,Francis Zvomuya,Allan J. Cessna,Francis J. Larney,Tim A. McAllister +10 more
TL;DR: The dissipation of ARG during composting of manure fortified with antimicrobials differs from manure generated by cattle that are administered antimicrobialbials in feed, and does not always align with the Dissipation of antimicrobial residues.
Journal ArticleDOI
Dissipation of Antimicrobials in a Seasonally Frozen Soil after Beef Cattle Manure Application.
Inoka Amarakoon,Srinivas Surac,Francis Zvomuya,Allan J. Cessna,Francis J. Larney,Tim A. McAllister +5 more
TL;DR: Field dissipation kinetics of chlortetracycline, sulfamethazine, and tylosin over a 10-mo period after fall application of manure from cattle were investigated, indicating a risk for residue build-up in the soil and subsequent offsite contamination.
