On 19 May 1983, 41 barrels of highly toxic chemical waste (dioxin-based), originating from theSeveso disaster, were found in an unused abattoir in Anguilcourt-le-Sart. The barrels, which had been illegally abandoned here by a transport contractor, were transferred the same evening to a military base near Sissonne. They were later destroyed in a high-temperature incinerator in Switzerald.[3]
