Largest Multi-State Food Poisoning Outbreaks of 2013: #1

Cyclospora Outbreak

A Cyclospora outbreak that began in June and sickened 631 people in 25 states before ending in late September was the largest multi-state food poisoning outbreak of 2013. Health investigators determined that the outbreak had multiple food sources and that most illnesses were linked to tainted produce imported from Mexico. Almost 80 percent of the cases were from three states: Iowa, Nebraska and Texas.  Public  health investigators in Iowa, which had 140 cases, and Nebraska, which had 87, determined that the source of illness in those states was commercial bagged salad mix produced by Taylor Farms of Mexico and served at Olive Graden and Red Lobster restaurants. The Centers for Disease Control (CDC) and the U.S. Food and Drug Administration FDA concluded that many of the 270 cases of … [Read more...]

Taylor Farms Salad Mix Not Source of TX Cyclospora Cases

Cyclospora Outbreak

Salad mix from Taylor Farms, which was identified as the source of Cyclospora illnesses in Iowa and Nebraska, is not the source of Cyclospora illnesses in Texas, according to the Centers for Disease Control and Prevention (CDC). As Food Poisoning Bulletin reported over the weekend,  the agency now believes that it's likely that there are multiple sources responsible for Cyclospora infections that have sickened more than 600 people in 22 states. Although Cyclospora is rare, there is a precedent for overlapping or back-to-back outbreaks. In 1997, more than 1,300 people contracted Cyclospora infections between March and July. Those illnesses were caused by three  different food sources (mesclun, raspberries and basil) from different countries. At least 610 cases of Cyclospora have been … [Read more...]

Clear of Cyclospora, Taylor Farms de Mexico Resumes Operations


Taylor Farms de Mexico,  the producer of mixed salad linked to Cyclospora outbreaks at Olive Garden and Red Lobster restaurants in Iowa and Nebraska, resumed operations yesterday after receiving an all-clear from the U.S. Food and Drug Administration (FDA).  The company, which had suspended operations August 9 during the agency's investigation,  has agreed to implement a comprehensive Cyclospora sampling program for leafy green and other products from their farms and processing facility in Mexico. The program will also include sampling water and continued monitoring of the sanitary conditions at the facilities. The FDA has inspected Taylor Farms de Mexico’s processing facility and five farms identified through the traceback investigation and found that conditions and practices were in … [Read more...]

CDC Cyclospora Expert Talks Outbreak Investigation


Two months ago, the Centers for Disease Control and Prevention (CDC) was notified of two non-travel related cases of Cyclospora infection in Iowa. Since that time, an outbreak has mushroomed to include more than 600 cases in 22 states and spawned and investigation that includes dozens of state, local and federal health officials. One of them is Dr. Barabra Herwaldt, a medical epidemiologist in the parasitic disease branch at the CDC and the agency’s resident expert on Cyclospora. She discussed the challenges of the investigation in an interview with Food Poisoning Bulletin. One of the key ways that this investigation differs from other high-profile food poisoning outbreaks is that genetic testing technology is available for infections caused by bacteria such as E.coli, Salmonella, … [Read more...]

Texas Has Most Cyclospora Cases, Does It Hold Key to Outbreak?


With more than 200 cases, Texas is the state hardest hit by the Cyclospora outbreak. Does it hold the key to outbreak investigation? The investigation of the Cyclospora outbreak which has now sickened at least 514 people in 17 states has been slow going. Outside of last week's announcement that pre-packaged salad from Taylor Farms in Mexico served at Red Lobster and Olive Garden restaurants was the source of illness for cases in those states, there haven't been many breakthroughs.  For example, we still don't know where else that salad mix may have been distributed or what other other food sources may be involved. No recalls have been issued in association with the outbreak. Federal health officials have joined a team of investigators in Texas, which now has almost as many cases as … [Read more...]
