According to this local Gilroy news article, McDonald's is sourcing the garlic from Christopher Ranch, so it is local to the area. It says the recipe was offered as a Garlic Festival special at one McD's location in Gilroy, sold out and was eventually expanded to most of the Bay Area McD's. It also says the fries are made to order by tossing the cooked fries with a purée of garlic, olive oil, parmesan cheese, parsley and salt.
I would expect them to get soggy quickly. A video of someone tasting them showed them being served with a fork.
