Mexico bans 183 toxic pesticides as U.S. lags behind on food safety

Mexico has taken bold steps to restrict harmful chemicals in its food supply. The country recently banned 183 highly hazardous pesticides still in use across the U.S., with another 35 set for prohibition in 2025. These moves come as Mexico strengthens its position as a global leader in organic farming, now boasting over 246,000 hectares of certified organic land. The Mexican government is gradually phasing out glyphosate, a widely debated herbicide tied to cancer and neurological problems. However, the process has faced delays due to pressure from American trade negotiators. Beyond glyphosate, Mexico has also outlawed synthetic food dyes linked to behavioural issues in children, preservatives such as BHA and BHT, and potassium bromate—a chemical often found in baked goods.

Across the border, the U.S. continues to permit many of these substances. The Environmental Protection Agency recently allowed the ongoing use of paraquat, a pesticide banned in China for its connection to Parkinson's disease. Meanwhile, the European Food Safety Authority (EFSA) has rejected or restricted hundreds of agricultural chemicals and food additives that remain legal in America. The EFSA follows a precautionary approach, banning substances until proven safe, while the U.S. typically allows them until harm is confirmed. Industrial farming in the U.S. has also led to a drop in the nutritional quality of produce. Soil degradation and a focus on high yields over nutrient-rich crops have weakened the health benefits of fruits and vegetables. Many American shoppers notice the difference—Mexican-grown produce often retains more natural flavour, while U.S. varieties, though visually perfect, can taste bland. These contrasting regulations coincide with rising health concerns in the U.S. Rates of obesity, chronic illness, and early-onset cancers among younger adults are higher there than in many other developed nations.

Mexico's stricter food safety policies set it apart from the U.S., where many banned chemicals remain in circulation. With a growing organic sector and tighter controls on additives, the country is reshaping its agricultural practices. The long-term effects of these decisions may influence both public health and trade relations in the years ahead.
