Friday November 28th:
A testing laboratory tells the Department of Agriculture that there is an unusual pattern developing in the sample.
Saturday November 29th:

Thursday, December 4th:
The Department of Agriculture issues a press statement saying restrictions have been placed on a number of pig farms following the discovery of contaminated animal feed.

The Dutch Food Safety Authority hears about the alert and contacts the FSAI to say they too have detected dioxins.
Belgian authorities said they had noticed increasing levels of PCBs and dioxins in September and French authorities also indicate concern.
