GERMANY is the country of the greatest concentration of food poisoning symptoms, according to new research.
Researchers at the University of Zurich have found that nearly one in three people in Germany suffer from one of the four food poisoning-related ailments.
The study, which was published in the German journal PNAS, surveyed nearly 3,000 people over a five-year period.
More than one-third of those who experienced food poisoning said they were severely ill, and another 25 percent said they had a mild illness.
Of the people who suffered from a food poisoning, almost half said they ate contaminated food at least once a week.
More than a quarter of those said they consumed contaminated food for a longer period of time than once a day.
Researchers found that about half of those affected experienced symptoms of nausea, vomiting and diarrhea.
Another 15 percent reported abdominal pain, nausea, fever, chills, and sore throat.
The number of people who reported experiencing food poisoning varied greatly between regions.
For instance, in the north, about a quarter reported vomiting, and in the south, about half reported symptoms.
In many parts of Germany, the number of food-related illnesses decreased over the last five years.
In 2015, the country had more than 300,000 reported cases of food poisonings, down from almost 1.5 million in 2012.
According to the study, the biggest factor in decreasing the number was a dramatic decrease in the number and severity of food poisoned.
About 80 percent of people surveyed reported that they had eaten contaminated food, compared to 70 percent in the same period in 2013.
And more than half reported experiencing symptoms, including vomiting, diarrhea, stomach pain, and headaches.
The researchers believe that more attention to food safety, which has led to a reduction in the numbers of food contaminated, is also leading to more illnesses and fatalities.
