Federal (USFDA) law strictly prohibits live animals from food markets except for police dogs and service dogs. California law goes further, requiring service dogs to have identifying tags.
These laws seem almost universally disregarded in San Francisco, by customers and store staff alike, The only place have I even seen a sign posted advising of the law is at the Walgreen’s in Chinatown, which doesn’t have much of a dog problem to begin with (no jokes please!) and the defunct Bristol Farms Market in the Westfield mall, but they are the exceptions.
Other than not liking dogs generally (and they don’t like me), I haven’t given much thought to this (who wants to harass a granny with a chihuahua in her shopping cart?) but recently I was grossed out in the Safeway across from the Caltrain station. One customer had set his basket down while perusing the meat counter, and another customer’s huge dog (on a leash, but within range) was sniffing at the contents of the first customer’s basket.
Does your local market enforce the “no live animals” law?
