Should travelers be more restricted to protect domestic crops from imported diseases and pests?

Ahead of the November 1-2, 2026, Dia de los Muertos holiday, U.S. Customs and Border Protection is restricting the entry of certain plants and fruits. Travelers are warned that unauthorized items will be seized to protect domestic agriculture.

Why it matters

Authorities are targeting these imports to prevent the spread of invasive insects and agricultural viruses that threaten American farms. These prohibitions are essential to stopping the movement of diseases like citrus greening and the tomato brown rugose fruit virus.

Regulatory prohibitions target specific items like orange jasmine and various fruits, including mangoes and guavas, known to host harmful pests. The restrictions follow long-standing efforts to contain citrus huanglongbing, which researchers first identified in Florida in 2005.

The players

U.S. Customs and Border Protection

This federal law enforcement agency is responsible for regulating and facilitating international trade and securing the borders of the United States.

The details

Prohibited items include tomato and pepper plants originating from Mexico, as well as marigolds intended for propagation. While cut marigolds are allowed, the border agency emphasizes that all agricultural products must be declared to avoid heavy fines.

The Big Picture

This enforcement strategy marks a continuation of national efforts to contain invasive pathogens following the 2005 Florida citrus huanglongbing detection. By restricting host plants, the government aims to prevent the permanent establishment of agricultural viruses that threaten domestic crop security.

Travelers crossing the border with prohibited plant materials risk immediate seizure and significant financial penalties. Avoiding the transport of restricted fruits and live plants remains the only way for individuals to bypass these regulatory barriers and avoid heavy government fines.

The takeaway

Travelers should verify the list of permitted agricultural products before attempting to cross the border during the holiday. Declaring all items to officials is the standard procedure to ensure compliance and avoid severe monetary penalties.
