Overdosing on salt Woolworths Biltong

I wrote to Woolworths consumer services months ago questioning the levels of salt in their free range beef biltong. I just had some more of this biltong and I am shaking uncontrollably from it. This has never happened before. I feel awful. This can’t be healthy and I will not buy it again. I have low blood pressure but what is this doing to those with high blood pressure? It’s awful.
