Description

The Esing Bakery incident, also known as the Ah Lum affair, was a food contamination scandal in the early history of British Hong Kong. On 15 January 1857, during the Second Opium War, several hundred European residents were poisoned non-lethally by arsenic, found in bread produced by a Chinese-owned store, the Esing Bakery. The proprietor of the bakery, Cheong Ah-lum, was accused of plotting the poisoning but was acquitted in a trial by jury. Nonetheless, Cheong was successfully sued for damages and was banished from the colony. The true responsibility for the incident and its intention—whether it was an individual act of terrorism, commercial sabotage, a war crime orchestrated by the Qing government, or purely accidental—remain matters of debate.
