Note:
Sams 1.1.1 In the proposed study, we will identify the extent of antimicrobial resistance (AMR) development in the field and examine the potential mitigation of food contamination in laboratory and greenhouse studies. This builds on prior research on triclosan (TCS) from personal care products (PCPs), an antimicrobial (AM) we detected at twice the median level of U.S. streams in Rio Grande waters (Kolpin et al., 2002; Wilson & Mendez, 2011; Wilson et al., 2015) and as high as 41 μg L-1 in a pilot study of South Texas irrigation waters. The highest estimated daily intake of triclosan for adults consuming sampled farm onions was calculated to be 141 μg kg-1 day-1 with a hazard quotient of 1.7 (Mendez, 2018a; Prosser & Sibley, 2015). We have not yet assessed other antimicrobials in farm products, although we expect elevated levels. The Rio Grande is the primary source of irrigation waters and is recharged with recycled waters and outfalls (6 million gallons per day of untreated sewage) from binational sources.
