In a statement, the agency said: "EFSA respects the right of citizens to protest peacefully and express their opinions about EFSA’s work. However, EFSA deplores the method chosen by the protestors to convey their views on this occasion.
"EFSA is proud of its record of engagement with stakeholders and pressure groups, including those that hold strong views about EFSA’s work. The Authority devotes a large proportion of its resources to ensuring that all voices are heard and will continue to do so in the future."
