urgent advise regarding cure please

[shanew]

I took the recipe for wiltshire ham some time ago i finally got round to making it, i did a nice piece of loin thats almost gone, but today i noticed this:

EDIT: Due to recently discovered information, this recipe is to be used at 10% pump only This is not an immersion cure
Quote:
Wiltshire cure ham wet method

Enough for 6.5 kg

Treacle 156 gm
Salt 156 gm
Black Pepper 5 gm
Beer 440 gm (440 ml Can of Beer)
Cure #1 = 20 gm (151 ppm Nitrite Ingoing)
Saltpetre 2 gm (257 ppm Nitrate Ingoing)
10 Juniper Berries

Weight of brine = 779 gm

Method

The beer flavor in this cure really comes through so choose a beer you like. Heat beer to boiling point .Then add salt, treacle and black pepper. Simmer for about 10 minutes. Remove from heat, let cool down add Cure#1 and Saltpetre. Weigh the brine and with preboiled water bring up to 779 gm. Now add the Juniper berries. Put meat and cure into a suitable container (non corrosive) and turn meat in the brine. Leave meat in brine, in the bottom of the fridge, for 5 days per 500 gm or no less than 14 days Turning every day.

Why must it only be used as a 10% pump? I used a 1.9kg loin and immersed it for 19 day's, i then washed it, boiled it and sent portions out to friends and family, im assumoing it will have been eaten by now, does this pose any health risk?

Hi jpj, please do be pedantic. There is a lot of confusion at the moment about immersion cures and if you can explain the difference between this and an immersion cure in laymans terms, I think you will greatly help in clearing this up.

it says that this cure would be enough for a 6.5kg piece of pork.
a 6.5kg piece sitting in that cure would not be fully immersed
it'd be too big
therefore it's not an immersion, just a wet cure
wet cures need to be turned frequently to ensure coverage/penetration etc
whereas an immersion cure would need overhauling (stirring up) on a less regular basis . . .
hope that makes sense?
