Four individuals are in custody as part of an investigation by the Antwerp federal judicial police and the Public Prosecution Service into the possible intentional spread of the tomato virus, ToBRFV. A tomato company from Rijkevorsel is suspected of developing a banned vaccine to deliberately infect tomato plants with ToBRFV. The European Union's zero-tolerance policy on the virus means these practices are illegal. A significant seizure was made during the searches, though the exact amount is undeclared. An investigation into tomato growers in the Netherlands is also underway.
