Turkey has faced a significant agricultural setback after harmful bacteria were detected in potatoes exported to Tunisia, leading to the return of 3,000 tons of potatoes at the border. The specific bacteria identified are 'Clavibacter michiganensis subsp. septonicus' and 'Ralstonia solanacearum', both posing significant risks to potato cultivation. 'C. michiganensis subsp. septonicus' is on quarantine lists worldwide due to its ease of transportation, while 'R. solanacearum' requires a ban on potato cultivation for five years after infection to prevent further spread. The incident has raised concerns about the oversight of potatoes sold in the domestic market, particularly those originating from the Nevşehir region.
