Buy food from Canada or the USA because of standards

Dec 11, 2025

International differences in food regulation can affect quality and safety. Here are some considerations when buying imports.

Peer-reviewed environmental and food safety research has documented heavy metal uptake (e.g., cadmium, lead, chromium) in crops and vegetables in India, often linked to soil, water and irrigation practices. Such studies conclude that levels frequently exceed international safety benchmarks and pose potential health risks, particularly to children exposed through diet over time.

Data from the European Union’s Rapid Alert System for Food and Feed (RASFF) indicate hundreds of Indian food products were identified with contaminants such as ethylene oxide (a carcinogenic sterilant), cadmium, mercury and banned fungicides over recent years — evidence that some exported batches failed to meet EU chemical safety standards.

Research has found elevated levels of heavy metals — especially cadmium (Cd), arsenic (As), lead (Pb), and chromium (Cr) — in agricultural soils in China, and these metals accumulate in food crops such as wheat and rice at levels that sometimes exceed safety limits. In one field study in Henan Province, Cd was the dominant pollutant and ~21 % of wheat samples exceeded China’s own limits.

These metals are persistent and may bioaccumulate — meaning they stay in soil and move up the food chain into grains and vegetables. Heavy metals have no beneficial nutrition and carry known health risks when consumed chronically, even at low doses.

China historically has had very high pesticide and fertilizer use compared with developed countries, and although usage has decreased recently, this legacy of agrochemical inputs still contributes to residues in food products. Peer-reviewed reviews of pollution-induced food safety problems in China identify pesticides and fertilizers as key sources of chemical residues in the food supply with implications for crop contamination.

Canada’s own monitoring data show a high overall compliance rate across all imported foods up to the latest published surveys, but imported fresh fruit/vegetables sometimes fall below target compliance rates — a reminder that vigilant testing is necessary given global supply chains.
