The European Food Safety Authority (EFSA) has performed studies revealing that three neonicotinoid pesticides: clothianidin, imidacloprid, and thiamethoxam, may be harmful for bees when sprayed on plant leaves. Bees are essential for pollination and have a significant impact on agricultural yield, and protectingthespecies is therefore amajorconcern. While a two-year ban is currently in place, environmental groups are appealing to the European Union to extend this ban. The EFSA plans to reassess the risks posed by the three chemicals and will determine the extent of their impact on bees.
