On March 17, 2025, Mexico adopted a constitutional amendment banning domestic cultivation of “genetically modified” corn

The only genetically engineered (GE) product in commercial production is GE cotton, with obsolete seeds and only in restricted areas. There has been no advance in plant or animal biotechnology development and production, mainly due to policy and regulatory constraints.

The Government of Tanzania continues to implement strict liability requirements on the commercialization of genetically engineered products, as outlined in the 2009 Biosafety Regulations. There are no genetically engineered products imported or commercialized in Tanzania. However, applied biotechnology is used for medicine and public health.

Following the June 2024 election of Claudia Sheinbaum as the next President of Mexico, the sitting President Andres Manuel López Obrador expressed intent to move forward with constitutional reforms in the September 2024 legislative session.

On April 17, 2024, the Government of Mexico published a law in the Official Gazette to establish mandatory warning labeling for products containing genetically engineered ingredients and to enshrine socioeconomic considerations into national food policy.

There are currently no genetically engineered (GE) products traded or commercialized in Tanzania due to the strict liability clause in the Biosafety Regulations of 2009. In September 2022, Tanzania’s Ministry of Agriculture reversed a 2021 ban on all...

Mexico's biotechnology regulatory policy environment has become increasingly uncertain under the current administration. The government has not approved any applications for genetically engineered (GE) products for food and feed use since May 2018 and has not approved any permits for planting GE crops since 2019.

On February 13, 2023, Mexico published a modified 2023 Corn Decree in the Diario Official Federal (DOF). The new Presidential decree abrogates the 2020 GE Corn Decree and is immediately effective on February 14, 2023.

Mexico has not officially reported any approvals for genetically engineered (GE) agricultural products for food and feed use since May 2018. Additionally, Mexico has not approved any permit applications for cultivation of GE crop (cotton and alfalfa)...

In September 2022, Tanzania’s Ministry of Agriculture directed the Tanzania Agriculture Research Institute (TARI) to identify a research station for trials of genetically engineered (GE) crops. This decision appears to reverse the Government of Tanzania’s (GoT) 2021 ban on all GE crop research trials.

Mexico has not reported any official biotechnology food or feed products approvals since May 2018. Additionally, Mexico has rejected or delayed all permit applications for cultivation of genetically engineered (GE) cotton in 2019, citing the precautionary principle.

The Government of Tanzania (GoT) uses a conservative, precautionary approach to manage genetically engineered (GE) products.
