The data is collected from 96 hospitals across the country and US territories, and ultimately produces "nationwide estimates of product-related injuries," according to its website.
The 2,300 incidents reported by the CPSC is just an estimate. The agency received 63 pizza-related injury reports itself, but its Epidemiology department extrapolated the data, projecting that 2,300 pizza-related ER visits occurred throughout the country in 2017.
As Joe Galbo, the CPSC’s social media specialist, told Munchies: “The FDA obviously regulates food, but we can find injuries associated with pizza by looking for it in the injury descriptions we receive from hospitals. Based on these reports our NEISS team uses an equation to create a national estimate of injuries.”
While the data might be foreboding, fear not the pizza. It isn't here to harm you.
