Quarterly Sampling Reports for antimicrobial resistance, specifically in cecal and product. Cecal reports consists of data for Salmonella, Campylobacter, E.coli, and Enterococcus. Product reports consists of data for Salmonella, Campylobacter, and Escherichia coli O157:H7 and non-O157 Shiga toxin-producing Escherichia coli (STEC). All reports are updated quarterly. See the FSIS website for additional information.

FSIS calculates prevalence, volume weighted percent positive, or percent positive calculations for microbial pathogens in FSIS regulated products that are currently sampled through existing sampling projects. FSIS intends to provide new calculations each quarter using the prior 12 months of sampling data. See the FSIS website for additional information.

We summarized the FY17 and part of FY18 results of the analysis of the effect of several parameters (e.g., total dissolved solids, specific competing metals, pH, and temperature) on REE recovery from geothermal brine in a manuscript that was submitted to Environmental Science & Technology. In this manuscript, we investigate biosorption as a potential means of recovering REEs from geothermal fluids, a low-grade but abundant REE source. We have previously engineered E. coli to express lanthanide binding tags (LBTs) on the cell surface and the resulting strain showed an increase in both REE adsorption capacity and selectivity. Here we examined how REE adsorption by the engineered E. coli is affected by various geochemical factors relevant to geothermal fluids, including total dissolved solids (TDS), temperature, pH, and the presence of competing trace metals.
