The 'cursed bread' of Pont-Saint-Esprit
In August 1951, some 250 people in Pont-Saint-Esprit fell ill with burning sensations and terrifying hallucinations after eating bread; several died and dozens were interned.

The account
Victims saw flames and monsters; one man tried to drown himself, convinced snakes were in his belly. The bread came from a single bakery.
The sceptical view
Official inquiry blamed ergot or a mercury-based fungicide in the flour. A 2009 book claimed a secret CIA LSD test, which historians widely reject.
The researched reading
A real mass poisoning traced to one bakery. Ergot or a toxic chemical in the flour is the most likely cause; the CIA theory lacks evidence.
| Explanation | Weight | Why |
|---|---|---|
| Something in the surroundings | 50% | Food poisoning from one bakery’s bread: ergot alkaloids (ergotism causes burning, hallucinations and convulsions) or a mercury-based seed fungicide (organomercury causes neurological symptoms) were the main official suspects; historian Steven Kaplan argued for a contaminant in the flour. |
| A known natural phenomenon | 17% | Other natural toxins, such as mycotoxins from moulds other than ergot, remain possible causes. |
| Perception, memory or mind | 12% | Fear and panic can amplify symptoms in a town where everyone ate the same bread; some cases may have been partly hysterical. |
| Undetermined | 11% | The share the reading had given to fabrication on doubt rather than evidence: the record does not settle it either way. |
| A hoax or fabrication | 5% | The 2009 claim of a secret CIA LSD test is unsupported by documents and widely rejected; it is an embellishment, not evidence. |
| A cultural story | 4% | The "cursed bread" became a legend, but the illness was real. |
| Genuinely anomalous | 1% | A poisoning with clear neurological symptoms needs no supernatural cause. |
Official position: Official inquiries blamed ergot or a mercury fungicide in the flour; no single cause was ever proven.
