I reply to a post on LinkedIn.

“The Patties Foods frozen berries scandal is a warning for directors about managing risks – what lessons could you learn? ”

My comment:

There’s lots of testing for bacterial contamination in such products as it’s regulated at Government level. Testing for viruses is not a routine requirement (it is not regulated). There’s been discussions on changing this as reportedly, about 20% of food contamination is caused by viruses and it might be a good idea to start testing.
