Many jurisdictions have implemented bans or taxes on plastic grocery bags based on environmental concerns. In 2007, San Francisco enacted a county-wide ban that included large grocery stores and drugstores. Los Angeles, Palo Alto, and other cities in California have followed suit.
In research carried out at PERC this summer, Jonathan Klick, a PERC Lone Mountain Fellow, argues that reusable grocery bags contain potentially harmful bacteria, especially coliform bacteria such as E. coli. Klick finds that, in the wake of San Francisco's ban, deaths and ER visits related to these bacteria spiked as soon as the ban went into effect. For more on this ongoing research, watch our interview with Klick above.
