Authorities have confirmed a second case of New World screwworm in Cochise County, Arizona. The recent detection involves a dog and a horse, marking another instance of the parasitic fly’s presence in the region.

The exact date, time, and venue for this public meeting were not immediately available. The purpose of such meetings typically involves educating residents about the pest, detection methods, and prevention strategies.

Officials have not released information regarding the specific actions taken following the confirmation of the second case, nor have details about any potential fines or code violations been provided. The contractor involved in any related response efforts was not named.

Further information is expected to be shared at the upcoming public meeting in Sierra Vista.
