Sigrid Mayrhofer

Sigrid Mayrhofer is a researcher at the University of Natural Resources and Life Sciences, Vienna (BOKU), affiliated with the Department of Biotechnology and Food Sciences and the Institute of Microbiology and Microbial Biotechnology. Her work focuses on molecular biotechnology, food microbiology, and antimicrobial resistance in food and animal systems.

Her research interests include antibiotic resistance in lactic acid bacteria and bifidobacteria, microbial safety of fermented foods, antimicrobial susceptibility testing, and probiotic safety assessment. She employs molecular and microbiological methods to analyze microbial communities in food, feed, and animal products, with a particular emphasis on public health implications.

Her recent publications and conference presentations center on the impact of feed additives on antibiotic-resistant bacteria in broilers and swine, safety assessments of Cambodian fermented foods, and detection methods for resistant E. coli. These works reflect a consistent focus on reducing antimicrobial resistance in the food chain through alternative strategies.
