these two deaths have been linked with the same company in UK...
Why authorities have not taken any action against the company?

How many deaths do we need for authorities to penalize the company?

What needs to be improved?
Which food legislation is not complete?

So many questions and so few competent answers...

P.S. deaths like the two above have occurred in Ireland as well with the most recent being this one...
