Palmstead Nurseries in Kent took a delivery this month which had four or five stowaways on board.
Marketing manager Nick Coslett said: "Apparently they were Afghans, who ran off across the field with police in chase. All this kept our dispatch teams working late into the evening.
"Of course we did not know how long they had been in truck so had to take extra hygiene/H&S precautions during unload and discovered a number of plants damaged and we have had to ask our grower to replace them. So if the trucks can bring in migrants undetected what hope have we with pathogens."
The truck was Romanian-registered truck but loaded in Italy.
Coslett suggested there was a need to treble the number of plant health inspectors at the docks. See more in HW next issue.
