MEXICO CITY, Sept 25 (Reuters) - Mexico's National Service of Agro-Alimentary Health, Safety, and Quality (Senasica) said on Thursday that a confirmed case of an animal infested with the New World screwworm parasite in Nuevo Leon state was possible thanks to protocols it established with the United States.

A fly-trapping system to detect screwworm flies in Mexico is checked every three or four days, Senasica told Reuters, a frequency determined with the animal health arm of the U.S. Department of Agriculture.

Senasica's comments came after criticism by U.S. Agriculture Secretary Brooke Rollins, who said Mexico had not adequately enacted protocols to curb the spread of the parasite.
