An easier starting point would simply be shifting meat subsidies to fruit and vegetables: Assuming your goal is to raise meat prices, the problem is if the US for example stops subsidizing meat it will just mean that people will buy more non-US meat, unless you at the same time slap on an import tariff (which is tricky to do). Taxing meat at the point of sale solves all those problems. That being said, you should probably also look at shifting subsidies towards making fruits and veg cheaper.
