Pathogens can survive in dry food for at least six months

imagesA new study, published by the University of Georgia in the Journal of Food Protection, has determined that food , like , survive for at least six months in cookies and crackers.

“There have been an increased number of outbreaks of diseases associated with of contaminated dry foods. We wouldn’t expect to grow in foods that have a very dry environment,” said Larry Beuchat, a Distinguished Professor Emeritus and in the UGA College of Agricultural and Environmental Sciences, who works with the Center for Food Safety on the UGA campus in Griffin.

The researchers used five different types of isolated from food in previous foodborne outbreaks and put the into four types of fillings found in cookies or crackers and placed them into storage.

The determined how long each type of was able to survive in each filling.

“The didn’t survive as well in the cracker sandwiches as it did in the cookie sandwiches,” Beuchat said.

In some cases, the pathogen was able to survive for at least to six months in the sandwiches.”The next steps would be to test all ingredients that are used in these foods,” Beuchat said. If there is a possibility that foodborne are present in specific ingredients, then the next step would be to stop the use of those ingredients.
