The global increase in pesticide use is linked to the rising demand for food brought on by population expansion, particularly in developing countries in Asia, Africa, Central America, and South America. Pesticides have increased agricultural productivity, preserved crop quality, and ensured a steady food supply. Despite these benefits, decades of ongoing production and usage of pesticides have led to grave concerns about the damaging effects these chemicals have on the environment and human health, especially when ingested into dietary chains. Scientists from all around the globe have looked at the usage of pesticides and food product contamination to address these issues. This summary covers research from the past and present on pesticide usage, pesticide accumulation in food, and reduction strategies that scholars have studied and reported throughout the years. Monitoring residual pesticide levels in soil crops, fruits, vegetables, and animal products is critically needed in developing nations to ensure they stay below Maximum Residue Limits (MRLs).
