Innkeeper Debbie O’Grady quipped: “One whiff and you’re stiff!”

Fiona Toomey, a former Pfizer worker, added: “Even the dogs here have been known to walk around in a state of sexual excitement.”

A spokesperson for Pfizer said: “Our manufacturing processes have always been highly sophisticated as well as highly regulated.”
