From the article: “Fruit portions were reduced and other products that could be used – including five-litre cleaning containers used to make the hooch – were either removed or moved away from inmates.”
We have done the same thing in Ohio. We were recently under a consent decree relating to the medical care of inmates that required fresh fruit to be served with meals. However, staff have said that some fruit is easier to make hooch from than others (oranges, for example, are easy; bananas, less so). Some institutions cut up the fruit so it is more difficult to carry away from the chow hall; others have ramped up searches of inmates when they leave the chow hall. Some institutions have also taken a close look at the containers used to make the hooch and tried to more closely regulate those. Across the system, institutions have also moved from selling sugar to providing only sugar substitute. It’s pretty much an ongoing battle, though.
