The FDA is investigating a five-state Cyclospora outbreak with iceberg lettuce as the reported vehicle [1]. An investigation is not a confirmed source, not a recall, and not a conclusion.

The paper's July 30 predecessor carried the CDC's incidence ledger — Michigan alone reporting 10,386 Cyclospora cases with 193 hospitalized [2]. The FDA's July 31 investigation page advances the record with a named vehicle. Iceberg lettuce is the reported category. The grower, distributor, root cause, and contamination point are unknown.

Cyclospora is a parasite that causes intestinal illness. It is not new. What is new is the five-state pattern and the FDA's decision to name iceberg lettuce as the reported vehicle before confirming the source [1]. The gap between "tied to" and "confirmed as" is where the reader's risk assessment lives. A reported vehicle names a product category. A confirmed source names a farm, a distributor, a lot number.

The FDA's investigation page is an active record. It does not name a recall. It does not name a grower. It does not name a distributor. It names iceberg lettuce as the vehicle the investigation is following [1]. The distinction matters: a recall pulls product from shelves. An investigation follows a trail. The trail has reached lettuce. It has not reached the source.

Food-safety investigations follow a pattern: cases cluster, a vehicle is identified, a source is confirmed, a recall is issued. The Cyclospora investigation is at the vehicle stage. The source stage — which farm, which lot, which distribution chain — is the next record. Until then, iceberg lettuce is a reported vehicle, not a confirmed cause.

The paper holds the stage. A reported vehicle names a category. A confirmed source names a responsibility. The FDA's investigation is at the first gate. The second gate — the source — determines whether this becomes a recall, a regulatory action, or an unresolved investigation.
