Protect Your Health: FDA Works to Ensure Your Favorite Berries Are Safe from Norovirus Contamination
In recent months, the FDA has unveiled a comprehensive initiative aimed at enhancing the safety of imported berries, a crucial step in preventing health risks associated with hepatitis A and norovirus outbreaks linked to these popular fruits. Understanding how to properly handle and consume berries can significantly mitigate these risks, ensuring that you enjoy their numerous health benefits without worry.
The rise in hepatitis A and norovirus cases connected to berries has prompted the FDA to take decisive action. These enteric viruses pose serious health threats, which is why it’s essential for consumers to stay informed about the safety measures in place regarding the berries they purchase and consume.
The FDA’s New Prevention Strategy
Since the late 1990s, berries have been implicated in multiple outbreaks of hepatitis A and norovirus in the United States. The FDA’s latest strategy aims to reduce the risk of contamination in imported berries, specifically focusing on imports from countries like Mexico and Peru.
According to FDA spokesperson Janell Goodwin, “The vast majority of fresh and frozen berries eaten in the U.S. are consumed safely. However, since 1997, enteric virus outbreaks have been linked to imported berries.” In light of this, the FDA is committed to improving safety standards. The plan involves:
- Enhancing food safety practices globally in the berry industry.
- Increasing scientific knowledge regarding the detection and containment of enteric viruses.
- Addressing the root causes of contamination outbreaks.
Understanding Berry Contamination
Research by the World Health Organization and the Food and Agriculture Organization of the United States has shown that frozen berries are significantly involved in norovirus and hepatitis A outbreaks. In fact, 2023 data reveals that a significant percentage of berries imported to the U.S. are sourced from other countries:
- 64% of fresh blueberries
- 95% of frozen blueberries
- 50% of frozen strawberries
- 91% of fresh raspberries
Mexico leads as the primary supplier of strawberries and raspberries, while both Mexico and Peru export blueberries. Contamination often occurs due to failures in food safety protocols, which can happen at various stages of the supply chain. Experts like Patti Ramos, MPH, RD, highlight the risks associated with workers who may unknowingly transmit these viruses, even while asymptomatic.
FDA’s Action Plan Against Contamination
After extensive investigations and consultations with industry specialists, the FDA has introduced a prevention strategy that focuses on:
- Implementing stringent hygiene standards for agricultural workers.
- Management of sanitary facilities to prevent virus spread.
- Monitoring virus transmission among workers.
The FDA aims to deepen its understanding of how viruses thrive in both agricultural settings and within the berries themselves. Goodwin mentioned that one goal is to advance scientific insight into the viability and detection of viruses present in fresh and frozen berries.
Mitigating Risks When Consuming Berries
While enjoying berries, it is crucial to recognize the potential risks of hepatitis A and norovirus, especially in frozen forms, which may harbor viruses longer. As noted by Ramos, frozen berries often show higher contamination rates than fresh ones:
- “Freezing preserves the virus and allows it to survive for longer,” said Ramos.
- Quoc Le advises consumers to favor locally sourced and domestically produced berries when available.
To reduce the chances of foodborne illness when consuming any berries, follow these precautionary steps:
- Rinse berries thoroughly under cold running water before consuming them.
- For a deeper clean, create a solution with one teaspoon of baking soda in one cup of cold water and soak berries for five to ten minutes before rinsing.
- Always wash utensils and surfaces with soap and water after slicing fresh berries to avoid cross-contamination.
Although concerns about contamination may lead some to avoid berries, it’s important to remember that there have been no outbreaks linked to domestically grown berries in over three decades. Plus, berries are exceptionally nutritious, rich in vitamin C, fiber, and antioxidants.
Ultimately, as Ramos states, “As with any public health concern, consumers must weigh the risks and rewards and make the choice that is right for them.” Incorporating safety measures when consuming berries can allow you to enjoy their health benefits while minimizing potential risks associated with foodborne illnesses.
