Glyphosate and glyphosate-based products have been extensively tested both in laboratories and in fields to evaluate potential toxicity to honeybees. The result of those tests show that they have neither acute nor chronic adverse effects to honeybees. This means that bees are neither killed nor damaged in case they get into contact with glyphosate.

For example, a comprehensive study by Thompson et al (2014) found no adverse effects on adult bee survival or bee brood survival or development in honeybee colonies treated with glyphosate at levels that exceed environmentally realistic exposures.

Regulatory authorities, such as the European Food Safety Authority (EFSA) and the U.S. Environmental Protection Agency (EPA), conduct comprehensive evaluations to ensure crop protection products, such as glyphosate, can be safely used in the environment when used in accordance with the label instructions.

As part of this process, regulatory authorities specifically evaluate the potential for effects on non-target organisms, including honeybees. Only products that pose no unacceptable risk to the environment are approved.
