The Dutch food standards watchdog NVWA has issued a stark warning to holidaymakers: avoid bringing home any souvenirs that could harbor invasive pests. Recent discovery of a Japanese beetle (Popillia japonica), a species notorious for its appetite for over 300 plant types, highlights the risks attached to hitchhiking insects and larvae hidden in soil, plant debris or packaged produce.
Originating in Japan and now established across parts of North America, this destructive pest has already made inroads in Europe, threatening the health of fruit trees, ornamental plants and agricultural crops. In the Netherlands alone, outbreaks have led to severe damage in nurseries and vineyards, prompting authorities to step up inspections at airports and border crossings.
Inspectors at Schiphol airport recently intercepted a specimen tucked inside a holidaymaker’s suitcase, concealed within a bouquet of flowers and soil clinging to gardening tools. “These beetles can decimate rose bushes, grapevines and oak saplings in just weeks,” explained an NVWA spokesperson. “Even a single individual poses a significant biosecurity threat.”
To prevent further incursions, the NVWA reminds travellers that any plant, fruit, seeds, cut flowers or soil brought from outside the EU must be declared on arrival. Some items require an official phytosanitary certificate, while prohibited goods will be confiscated and destroyed.
NVWA’s essential advice for travellers:
- Declare all plant, animal and soil products at customs on arrival.
- Obtain a phytosanitary certificate for permitted items purchased abroad.
- Clean footwear, garden tools and outdoor equipment before packing.
- Inspect luggage and souvenirs thoroughly to remove any insects or larvae.
- Dispose of unwanted plant materials in designated waste bins, not in the garden.
By following these simple precautions, holidaymakers can help protect the Netherlands’ rich biodiversity and agricultural industry from invasive species that threaten landscapes and livelihoods.
