When I was growing up we had a LOT of pigs. Cleanings from the farrowing houses, which were on straw, were added to the huge muckheap - added at one end and used from the other, so that by the time the resultant FYM was used on veggies or the fields it was at least two years old. We never spread liquid slurry - that went into a collecting tank but didn't go on the land (I can't remember where it did go) . Dad grew amazing veggies. The things to look out for are heavy metal contamination in pig manure and parasites transmissable to humans. You will be fine growing tomatoes as the part you eat doesn't touch the ground, but I wouldn't grow roots, tatties etc in it this year. It will be fine next year but in future compost it for at least a year before you use it.
Having said that, when we kept pigs here we used them to clear a veg patch then planted into it straight away. That was about 15 years ago and we're both here to tell the tail, with neither heavy metal poisoning nor terminal worms

. After my Dad gave up the pigs, it took several years to get rid of the smell, although we couldn't smell it
