The US Animal and Plant Health Inspection service (APHIS) has detected New World screwworm in a cow in Mexico, leading to the suspension of cattle trade between Mexico and the US. The parasite's spread in Mexico could potentially impact US cattle producers by reducing the supply source. If the infestation spreads, it could significantly limit or suspend trade for an extended period. This could impact the US beef market, which was already expected to have less supply in 2025 and 2026 due to various factors.
