Mexico will begin releasing sterile flies within two weeks to combat the New World screwworm, President Claudia Sheinbaum said, according to reporting from [La Jornada](https://www.jornada.com.mx/?ref=lacaribenanews.com).

The pest-control measure carries regional interest across CELAC agricultural economies.

## What did Sheinbaum announce?

Sheinbaum said the release of sterile flies to fight the screwworm will start in two weeks, La Jornada reported. The outlet cited the sterile fly technique as the control approach.

## When does Mexico expect to control the pest?

Mexico foresees controlling the screwworm in August and reopening the border to cattle exports, Sheinbaum said, according to Infobae. The outlet tied the pest-control timeline to the resumption of livestock exports.

For cattle producers across the region, that August target sets the clock on when Mexican livestock trade can flow again. Food security remains a live concern across the bloc, with [Belize emerging as CARICOM's food security benchmark](https://www.lacaribenanews.com/belize-emerges-as-caricoms-food-security-benchmark-as-regional-deadline-slips-to-2030/) as the regional deadline slips.
