[4] While the presence of undeclared meat was not a health issue, the scandal revealed a major breakdown in the traceability of the food supply chain, and the risk that harmful ingredients could have been included as well.
[citation needed] The next day, 15 January 2013, the FSAI advised the five retailers concerned, Tesco, Dunnes Stores, Aldi, Lidl and Iceland, of their findings;[6] all these firms withdrew the offending products.

[31] Spanghero imported meat from Romania and sold it on to another French company, Comigel, which made frozen ready meals at its factory in Luxembourg.
French Consumer Affairs Minister Benoît Hamon said the meat had left Romania clearly and correctly labelled as horse and that it was afterwards that it was relabelled as beef by Spanghero.
[31] The investigation also said some blame may rest with Comigel, claiming the staff there should have noticed anomalies in the paperwork, and realised from the smell and look of the meat once it was defrosted that it was not beef.
[33] The source of the horse meat was third party supplier Comigel, a French-headquartered frozen ready meal producer, from its subsidiary Tavola factory in Capellen, Luxembourg.

[72] In April 2013, the FSA reported it had not only found more than 1% horse DNA in Asda's 340 gram tins of "Smart Price Corned Beef" but it also contained four ppb of phenylbutazone, marking the first time since the start of the scandal that bute had been detected in a meat product in the UK food chain.
[73][74] However, one problem raised was over documentation; all of the UK animals with phenylbutazone contamination tested in early 2013 possessed a "horse passport" that allowed the carcasses to be sold for human consumption.

[106] In October Barry Gardiner MP, the UK shadow Environment minister criticised the lack of prosecutions of leading players ten months after David Cameron promised that everything possible would be done to deal with a "very shocking" crime.

"[107] On 26 August 2016, Andronicos Sideras, owner of Dinos and Sons Ltd, was charged with conspiring with Ulrich Nielsen and Alex Ostler-Beech, of Flexi Foods, to sell horsemeat as beef between 1 January 2012 – 31 October 2012 by the City of London Police.
