In a letter to parents, the City of Copenhagen said that listeria was found in tzatziki served to school kids as part of a public-run lunch programme.
“We are writing to you because your child has eaten EAT [the name of the school food programme, ed.] on Tuesday, November 11th and it has now been found that there was listeria in the tzatziki,” the letter reads, according to broadcaster DR.
The EAT programme delivers lunch to 40 different schools and the infected tzatziki was one of two lunch options offered on November 11th. According to a city official, around 3,000 of the up to 5,000 children who get their meals from the programme are through to have chosen the infected dish.
“We are clearly taking this very seriously, and are currently following all of the recommendations from Fødevarestyrelsen [the Danish Food and Veterinary Administration, ed.] in order to ensure it doesn’t happen again,” Lina Maria Johnsson, the head of the city’s health department, told DR.
It is uncertain if the listeria stems from the cucumber, garlic or yoghurt used in the tzatziki, or from unhygienic conditions at EAT’s kitchens.
The Food and Veterinary Administration has taken samples from the food and in the meantime has ordered EAT to give its facilities a thorough cleaning.
An administration spokesman tried to assuage parents’ fears.
“If you are weak and sick, there can be a risk. But schoolchildren aren’t,” Bjørn Wirlander told DR.
