Florida tightens restrictions on dogs and cats from Texas and New Mexico due to screwworm

### What happened
Florida’s Commissioner of Agriculture, Wilton Simpson, has strengthened and extended an emergency rule restricting the importation of shelter dogs and cats from Texas and New Mexico, following new detections of the New World screwworm (Cochliomyia hominivorax). The measure, reported by press sources, aims to prevent the pest from entering Florida, where livestock farming is a key sector. The previous rule already had restrictions; this one reinforces and extends its duration.

### Context
The screwworm is a fly that infests wounds in warm-blooded animals, causing severe economic and health damage. The United States is facing an outbreak in southern areas, particularly Texas and New Mexico. The emergency rule is part of efforts to contain the pest. In foreign trade, such phytosanitary restrictions can affect the movement of live animals and regional supply chains, although its direct impact on Mexico is still to be assessed.
