There, the livestock will again undergo inspection by Mexican National Service for Health, Safety, and Food Quality (SENASICA) and APHIS officials before crossing at the Santa Teresa and Douglas ports of entry, respectively, according to the announcement.
Additional pre-export inspection pens and trade reopening through other ports of entry may come in the near future.
In the last two years, screwworm has spread north of the biological barrier established in Panama and into Costa Rica, Nicaragua, Honduras, Guatemala, El Salvador, Belize, and, most recently, Mexico. Multiple factors are behind the increase, according to APHIS, including new areas of farming in previous barrier regions for fly control and increased cattle movements into the region.
To eradicate NWS, APHIS is releasing sterile flies through aerial and ground release at strategic locations, focusing on southern Mexico and other areas throughout Central America. A complete list of regions APHIS recognizes as affected by screwworm, along with more detailed information on trade restrictions, can be found on the APHIS Animal Health Status of Regions website.
In related news, on January 21, APHIS resumed equine imports from Mexico with the implementation of a similar NWS safety protocol.
