Bird flu in Pennsylvania: Here's what to know

• At least 66 human cases have been confirmed in the U.S. since April, per CDC data as of Tuesday. So far, none are in Pennsylvania.

What they're saying: Although egg prices are creeping up in the Keystone State, there have been no reports of any rationing, Alex Baloga, president of the Pennsylvania Food Merchants Association, tells Axios.

• "It hasn't gotten to the point where we've seen customers' purchases being limited," he says, adding the group is continuing to monitor the issue.

Zoom in: Bird flu is suspected of killing hundreds of snow geese last week in the Allentown area.

• The approximately 200 dead snow geese were discovered at Lower Nazareth Township in Northampton County and Upper Macungie Township in Lehigh County, per a Pennsylvania Game Commission news release.
• Preliminary testing of the birds indicated the presence of the virus. Additional testing is ongoing.

Threat level: The Philadelphia Department of Health issued a health alert late last month about the H5N1 bird flu.

• But bird flu is "primarily an animal health issue" and poses a low risk to humans, per the CDC.

• No cases of the virus have been reported in animals in Philly, health department spokesperson Jim Garrow tells Axios.
• Health officials are "watching the situation closely" and working with health care providers to identify any possible cases.

Meanwhile, Pennsylvania is requiring farms to take preventative measures. The state has mandated bulk testing of milk for the virus since November.

• While not typically fatal for dairy cattle, the virus can severely affect milk production, per a news release from the Pennsylvania Department of Agriculture.

Context: The bird flu outbreak began in January 2022 and has since spread to wild and domestic birds in every state, per the game commission.
