Belize Enacts New Law to Prevent Spread of New World Screwworm

In response to the growing threat posed by the New World Screwworm (NWS), the Belize Agricultural Health Authority (BAHA) and the Ministry of Agriculture, Food Security, and Enterprise (MAFSE) have enacted Statutory Instrument No. 143 of 2024. The new regulations aim to prevent, control, and eradicate the deadly parasite, Cochliomyia hominivorax, which has been steadily spreading through Central America.

The decision comes after confirmed NWS cases in neighbouring Guatemala and Mexico. This prompted authorities to increase Belize’s threat level to “extremely high.” The regulations, which took effect on November 8, 2024, empower BAHA and MAFSE to strengthen preventive measures and implement control and eradication protocols if necessary.

The new law outlines several key measures to safeguard Belize’s livestock and animal health. These include:

Mandatory reporting: All cases of myiasis (wound infestation by larvae) must be reported to the nearest BAHA office, MAFSE office, or healthcare provider.

Animal health inspections: Small stock and livestock must be physically inspected and possess an NWS Health Inspection Certificate and Movement Permit before being transported.

Controlled animal movement: Movement of animals must occur during daylight hours, and all animals (including pets) must be declared at Animal Movement Control Points.

Regulated imports: Animals can only be imported with BAHA’s approval and authorization. Imports through non-established points of entry are strictly prohibited.

Violations of SI 143 of 2024 carry severe consequences. Anyone found in breach of the regulations may face fines of up to $5,000, imprisonment for up to three years, or both.

BAHA and MAFSE are calling on farmers, animal transporters, and the public to comply with the new measures to prevent the entry of NWS into Belize. Authorities have emphasised that the illegal movement of animals is a primary driver of the parasite’s spread.

The New World Screwworm is a highly destructive pest that feeds on the flesh of warm-blooded animals, causing severe health risks to livestock and pets. BAHA is urging stakeholders to remain vigilant, prioritize animal inspections, and report any suspicious cases of myiasis to prevent a potential outbreak.
