Welcome to A4A! Don't worry about posting here zigzig. You can talk about garden related stuff under all the various headings and there's the Shed and Watershed for general topics. There's also the chatroom where you'll find a few folks of an evening.
It does sound very much like you had contaminated manure, but it's not life-threatening - at least we hope not. When it became a problem last year, the RHS, DEFRA etc were initially advising not to eat affected crops. That advice changed in July after Dow who manufacture the weedkiller submiitted additional test data indicating that it probably poses no risk to human health.
The weedkiller will still be in your soil - it doesn't disappear until every trace of straw has disintegrated. You can speed this up by digging over the affected areas, more than once if you can manage it. You can also rotate your crops around so that the things which are unaffected/less affected by it are in the manured areas. Badly affected crops include potatoes, tomatoes, peppers, aubergines, lettuce, beans and peas. Other stuff seems o be OK, or at least grows through the problem.
The manufacturer voluntarily suspended the weedkiller products in July as a result of all the adverse reports so no spraying has been done since. But, there is still animal feed in the supply chain that has been sprayed and a lot of manure stacked that might be contaminated. At the moment, use of manure is risky unless you can be absolutely sure that the animals that produced the manure were not fed on anything that had been sprayed or that the manure is older than 3 years (when these weedkillers were introduced). And the weedkillers may be re-introduced, the manufacturer has been working towards fulfilling the conditions laid down by DEFRA for it's re-approval.
