05 Oct 2017 --- High concentrations of neonics has been found in honeys from North America, Asia and Europe, according to a study published in the leading scientific journal Science by an interdisciplinary team from the University of Neuchâtel and the Botanical Garden of Neuchâtel, Switzerland. Three-quarters of the honey produced throughout the world contain neonicotinoids (neonics) – a class of pesticides known for their role in the decline of bees and for their harm to a large number of non-target species. The measured concentrations of neonics are, however, below the maximum authorized levels for human consumption.
