If you live in New York City, avoiding dog feces on the sidewalk is an art form. But do fecal bacteria persist on the sidewalk after the feces are picked up? Can the bacteria transfer to your shoes? And to the indoors?

Professor of Chemistry Alessandra Leri, Ph.D., and Biology alumna Marjan Khan ’20 set out to answer these questions by quantifying the fecal pathogens enterococci and E. coli on New York City sidewalks, on shoe soles, and in the indoor environment.
