A cyclospora outbreak is spreading across the US, with officials investigating a link to shredded iceberg lettuce at Taco Bell locations in five states. Health experts advise caution when consuming raw produce, but the risk remains low.

Why it matters

The cyclospora outbreak highlights the importance of food safety and the need for consumers to be aware of the risks associated with consuming raw produce.

A tiny parasite called cyclospora is making people sick with diarrhea. It's spread through food that hasn't been cooked, like salads. Health experts say the risk is low, but people should be careful when eating raw produce.

Analysis

A Growing Concern: Cyclospora Outbreaks in the US

Cyclospora outbreaks have been a recurring issue in the US, with previous outbreaks linked to fresh produce such as bagged salad mixes, cilantro, basil, raspberries, snow peas, and green onions. The current outbreak, which has been reported in 34 states, has led to a surge in cases of diarrhea-causing parasite infections. The Centers for Disease Control and Prevention (CDC) has reported 1,645 laboratory-confirmed domestic cases of cyclosporiasis and is investigating 5,100 additional reports.

The Role of Shredded Iceberg Lettuce

The CDC has identified a link between shredded iceberg lettuce served at Taco Bell locations in five states and the cyclospora outbreak. The agency has advised consumers to avoid eating shredded lettuce from Taco Bell locations in those states. Taco Bell is working to remove the contaminated produce from its locations and is also working with the supplier to determine whether any was sent to other locations.

The Importance of Food Safety

While the risk remains low, health experts advise that people should be cautious when consuming raw produce. Dr. John Openshaw, an infectious disease physician and medical epidemiologist at Stanford University, notes that even though the number of people involved in the current outbreak or outbreaks seems large, the risk remains very low to most people. He advises that people should not necessarily avoid produce, but rather be aware of the risks associated with consuming raw produce.

The Symptoms of Cyclosporiasis

The most common symptom of cyclosporiasis is watery diarrhea that can be frequent and sometimes 'explosive.' Other unpleasant symptoms can include stomach cramps, nausea, loss of appetite, bloating and gas, fatigue, vomiting, and a low-grade fever. Unlike deadlier foodborne illnesses such as listeria or E. coli, cyclosporiasis is unlikely to be life-threatening. The biggest risk right now during the hot summer months is dehydration.

Conclusion

The cyclospora outbreak highlights the importance of food safety and the need for consumers to be aware of the risks associated with consuming raw produce. While the risk remains low, health experts advise that people should be cautious when consuming raw produce and take steps to prevent dehydration.

Key points

  • A cyclospora outbreak is spreading across the US, with officials investigating a link to shredded iceberg lettuce at Taco Bell locations in five states.
  • Health experts advise that the risk remains low, but people should be cautious when consuming raw produce.
  • The most common symptom of cyclosporiasis is watery diarrhea that can be frequent and sometimes 'explosive.'
  • The biggest risk right now during the hot summer months is dehydration.
  • Taco Bell is working to remove the contaminated produce from its locations and is also working with the supplier to determine whether any was sent to other locations.
The Upside

If the contaminated produce is removed from Taco Bell locations and the supplier takes steps to prevent future contamination, the risk of cyclosporiasis could decrease. Additionally, health experts are working to raise awareness about the importance of food safety and the risks associated with consuming raw produce.

The Downside

If the contaminated produce is not removed from Taco Bell locations and the supplier does not take steps to prevent future contamination, the risk of cyclosporiasis could increase. Additionally, if people do not take steps to prevent dehydration, they may experience more severe symptoms or complications.
