FDA to develop food safety prevention strategy for berries

The U.S. Food & Drug Administration (FDA) has announced that it is developing a food safety prevention strategy to enhance the safety of fresh and frozen berries, in response to a history of hepatitis A (HAV) and norovirus (NoV) outbreaks linked to the berry consumption.

In the U.S., there have been four HAV outbreaks and three NoV outbreaks linked to frozen berries from 1990 to 2016, and since 2011, there have been three HAV outbreaks linked to fresh berries, including a current outbreak linked to fresh organic strawberries. 

Moreover, globally, from 1983 to 2018, there were 50 outbreaks attributed to frozen berries: 36 caused by NoV and 14 by HAV, according to the FDA’s statement.

Freezing preserves berries but generally does not inactivate viruses that may be introduced at various points in the supply chain, such as by infected workers, contaminated water or contaminated food contact surfaces. In addition, fresh berries are generally eaten raw without a kill-step that could eliminate pathogens.

Much like ongoing prevention work for other commodities, such as leafy greens, tahini, and imported specialty mushrooms, the food safety prevention strategy for berries will be informed by the findings of surveillance sampling. 

In August, the FDA plans to resume an assignment to collect and test frozen berries that it paused at the start of the COVID-19 pandemic. The assignment seeks to estimate the prevalence of HAV and NoV in frozen strawberries, raspberries and blackberries and help the FDA identify sites where practices or conditions may exist that constitute safety vulnerabilities. 

To date, the FDA has collected and tested more than 1,100 samples under this assignment and plans to collect and test about 427 more to meet the assignment’s public health goals. The agency does not plan to collect or test any additional frozen strawberries as it has already met its collection target for that commodity.

In addition, the FDA plans to work collaboratively with industry, academia, and regulatory partners in the development of the food safety prevention strategy to identify measures that can be taken to limit or prevent contamination from occurring throughout the berry supply chain. 

Furthermore, the FDA will develop approaches to re-enforce control measures and their application, and areas where additional research is needed.
