Ironically, as per the IKEA website:
What we are proud of
We want to offer quality food products at low prices. At the same time we want you to know that we source food products in a responsible manner. We are working in all parts of the food chain, from the farm to the IKEA store, to be able to offer food you can trust...
Food safety760kg (1,672lb) of the meatballs were stopped from going on sale after the contamination was discovered.
We want our customers to feel confident that the food served and sold at IKEA is safe and of good quality. That is why we require our suppliers to have special quality programs in place.
Also, all our stores in the UK & IE are subjected to independent, unannounced food safety management audits to ensure the highest level of food safety training and food safety standards."
As I have noted before, take a leaf out of IKEA's book, don't buy ready made meals but "self assemble" your food (ie make it and cook it yourself) by buying the ingredients from trusted local butchers.
