The presence of highly pathogenic avian influenza (HPAI) has been confirmed in an egg-laying flock in Peru.

According to a report from the World Organisation for Animal Health (WOAH), the owner of a farm in Arequipa reported in increased mortality in the 13-week-old birds. The chickens showed signs of hoarseness, as well as crest and wattles cyanosis.

The flock included 1,708 chickens, and 74 of those birds were confirmed as HPAI cases. Of those 74, 62 had died.

The virus is of the H5 (N untyped) variety, WOAH stated.

Control measures are being implemented, including stamping out, traceability, quarantine, disinfection, surveillance within and outside of the restricted zone, movement control, official destruction of animal products and official disposal of carcasses, byproducts and waste.

Prior to this, the last time HPAI was detected at a commercial poultry operation in Peru was in February, when a flock of 27,000 laying hens in Chepén was affected.

Non-commercial cases of HPAI in Peru

On the same day WOAH issued a report concerning the layer flock infection, it issued another oat a non-commercial flock, describing the affected birds merely as “non-poultry birds.”

The affected farm is in the Dean Valdivia District.

According to WOAH, the flock involved 70 birds, of which, 66 were considered positive cases, with six of those birds being deceased.

The birds had been displaying hoarseness, weakness and head oedema.

Since November 2022, WOAH has reported 13,733 non-poultry birds in Peru as susceptible to HPAI.
