In the post-Covid era, ensuring food safety is of the ultimate importance. It is essential to clean vegetables and fruits properly before consumption, and this has been highlighted many times in the past two years. Recently, World Food Safety Day was celebrated on June 7 by the World Health Organization (WHO) to emphasise the importance of eating healthy, safe and chemical-free food and, thus, help prevent food-borne diseases too. And now, technological innovation is aimed at solving food safety concerns, especially for fresh produce. Researchers at Sweden’s Karolinska Institute have invented a small sensor that may be useful in detecting pesticides on fruits.
