The FDA has identified the second source of the cyclosporiasis outbreak — a fresh herb product (cilantro or fresh basil, per early sourcing) from a separate Mexican supplier that is not connected to Taylor Farms de Mexico. A second voluntary recall is expected to be formally announced within 24-48 hours. The identification of the second source confirms that the Taylor Farms recall alone was insufficient to stop the outbreak — and that anyone who carefully avoided Taco Bell salads during the exposure window may still have been exposed through this second contaminated product.

WHY HERBS ARE A RECURRING CYCLOSPORA VECTOR

Fresh cilantro has been linked to multiple US cyclospora outbreaks — most significantly a 2015 outbreak affecting 546 people in 31 states that was traced to cilantro from the Mexican state of Puebla. The mechanism is the same: cilantro is grown in fields irrigated with water that may contain human fecal contamination; cyclospora oocysts are deposited on the leaves; the herb is minimally processed and consumed raw. Unlike leafy greens (which can be washed, though imperfectly), cilantro’s complex leaf structure makes cleaning even harder.

Fresh basil has similar vulnerability. Both herbs are imported heavily from Mexico during the US summer season — the same seasonal window that produces cyclospora outbreaks. Both are used in restaurants, sold fresh in grocery stores, and consumed without cooking. The FDA’s traceback methodology is designed for exactly this supply chain — finding which specific grower’s cilantro or basil tested positive and issuing the recall to that batch.

WHAT THE SECOND RECALL MEANS FOR CONSUMERS

▸  If you consumed fresh cilantro or fresh basil from a restaurant or grocery store in the May-August 2026 exposure window, you may have been exposed to the second source

▸  If you developed watery diarrhea, nausea, fatigue, or abdominal cramping after consuming fresh herbs in this period, seek medical evaluation — cyclospora is treatable with trimethoprim-sulfamethoxazole (Bactrim)

▸  The FDA recall will be posted at FDA.gov — check the specific brand and origin if you have fresh herbs in your refrigerator

▸  Cooking destroys cyclospora — cooked food incorporating these herbs is not a risk

CONFIDENCE: MODERATE

Second source identification is from available reporting — specific product has not been formally released as of early August 8 publication time. Cilantro and fresh basil as likely categories are from epidemiological pattern of prior outbreaks. FDA recall timing (24-48 hours) is from industry sources. All consumers should check FDA.gov for the official recall once published.

QUESTIONS YOU MAY STILL HAVE

Q: Does this mean the outbreak will stop now?

A: If both sources are recalled and the second source is effectively pulled from the market, new exposures should stop — but cases from existing exposures before the recall will continue appearing for 2-14 more days (the incubation period). The total case count will continue rising for another week or two even after both products are recalled.

Q: How many additional cases came from the second source?

A: Not yet known. The FDA’s epidemiological analysis will estimate what fraction of the 11,200+ Michigan cases and nationwide cases are attributable to the second source versus Taylor Farms. This will also determine civil liability questions.
