If you saw a headline last week that said the FDA “retracted” its positive test on Taylor Farms lettuce and thought, wait, does that mean the recall is over? — you’re definitely not alone. That single word, “retracted,” did a lot of damage to how people understood this outbreak. So let’s clear it up.

What Actually Happened

Over one weekend in July, the FDA announced that a sample of Taylor Farms lettuce had tested positive for Cyclospora. It sounded like the smoking gun everyone had been waiting for. Then, the very next day, the agency walked it back, saying its lab experts had re-reviewed the result and it “should be considered a false positive.”

Cue the confusion. A lot of people understandably read that reversal as “Taylor Farms has been cleared.” It hasn’t.

Why The Retraction Doesn’t Change The Recall

Here’s the distinction that got lost in the headlines: the positive test that got retracted wasn’t even from the same batch of lettuce tied to the outbreak. It came from a separate sample collected during a border screening, a different lot entirely. This means walking it back didn’t remove a key piece of evidence from the actual case against Taylor Farms; it just corrected an unrelated data point.

The FDA said as much directly, stating on social media that:

  • The false-positive lab sample does not change the basis for the ongoing outbreak investigation
  • The agency’s traceback data and epidemiological evidence still point to Taylor Farms’ shredded iceberg lettuce from central Mexico
  • The voluntary recall remains fully in effect

So Why Hasn’t There Been A “Real” Positive Test?

This is the part that actually explains a lot. Cyclospora is notoriously difficult to detect in a lab setting, even when it’s really there. It can be present on produce in such small amounts that routine testing methods simply aren’t sensitive enough to catch it, and that is part of why food safety investigators lean so heavily on epidemiological evidence (tracking what sick people ate and where it came from) rather than waiting on a lab confirmation that may never come.

In plain terms: the absence of a confirmed positive test isn’t unusual for this particular parasite, and it isn’t the same thing as evidence pointing away from Taylor Farms.

Where Things Stand Now

  • The recall of Taylor Farms’ shredded and blended iceberg lettuce from central Mexico is still active
  • The CDC and FDA’s traceback investigation still considers this lettuce the leading suspect in the outbreak
  • Taylor Farms itself has continued its voluntary recall despite the retraction
  • If you have any of the recalled product, the guidance hasn’t changed: throw it away, don’t eat it

Bottom line: a retracted test made for a confusing 24 hours, but it didn’t change the actual food safety guidance. If you’re still holding onto recalled lettuce, that part of the story hasn’t budged.
