FDA Places Mexican Mango Production Unit on Red List over Salmonella; SENASICA Clarifies It Is Not Listed in Its Contamination Risk Reduction Systems Directories

The National Service for Agri-Food Health, Safety and Quality (SENASICA) reported on October 12, 2026, in its Agri-Food Safety Monitor, that on October 9 the U.S. Food and Drug Administration (FDA) updated Import Alert 99-23 and added a mango production unit to the List of Firms and Products Subject to Detention Without Physical Examination, known as the Red List, due to the detection of Salmonella spp. Import Alert 99-23 provides for the detention of fresh agricultural products due to contamination with microorganisms pathogenic to humans.

According to SENASICA's document, the alert considers contamination risks during cultivation, harvest, packing, storage, processing, and transport. In accordance with Chapter 9 of the FDA Regulatory Procedures Manual, inclusion on the Red List may be supported by two or more positive Salmonella spp. results in the same shipment or in several related shipments, among other evidence. Shipments from the listed unit may be detained at the border without physical examination, and the importer must demonstrate through analysis that the product is not contaminated in order for it to be released.

SENASICA specified that the production unit is not registered either in the General Directory of Companies Recognized under Contamination Risk Reduction Systems (SRRC) or in the Directory of SRRC-Certified Companies for mango cultivation, both updated as of September 30, 2026. SRRC are the national good practices scheme for primary production, whose objective is to reduce the likelihood that biological agents contaminate food. Salmonella is a bacterium associated with intestinal infections from fruits and vegetables; in mango it can enter through irrigation water, soil, handling during harvest, or contaminated packing surfaces, and it is one of the causes of detention of Mexican fresh fruit at the border.

For mango producers and packers, the Red List means that each subsequent shipment must be accompanied by analysis from an accepted laboratory before it can enter the United States, with the associated costs and delays, and it is an incentive to verify water, packing surfaces, and lots before shipment. Specio 1.1 from TAAG detects Salmonella spp. by real-time PCR with melting curve analysis in food, beverages, and surfaces, but mango does not appear among its explicitly validated matrices, so its use would be a supporting verification and not a replacement for the method required by the buyer.
