Tesco meatloaf horsemeat find

More than half of consumers have changed their shopping habits as a result of the horsemeat scandal, a survey for consumer group Which? has found.

It also found that public trust in the food industry has dropped by 24%, with 30% of those polled now buying less processed meat and a quarter (24%) buying fewer ready meals with meat in or choosing vegetarian options.

The results of the survey comes as supermarket giant Tesco announced it had withdrawn a line of its frozen meatloaf after tests revealed it contained between 2% and 5% horse meat.

Populus surveyed 2,064 UK adults online between February 22 and 24.

Many of the UK's biggest food firms and supermarkets have recalled beef products since January after tests found they contained horse DNA.

A first wave of tests found horse DNA in products including Aldi's special frozen beef lasagne and special frozen spaghetti bolognese, Co-op frozen quarter-pounder burgers, Findus beef lasagne, Rangeland's catering burger products, and Tesco Value frozen burgers and Value spaghetti bolognese.

A second wave of tests revealed contamination of Asda's chilled beef bolognese sauce, beefburgers, minced beef and halal minced beef sold by Sodexo, which supplies food to schools, care homes and the armed forces, and a Whitbread Group lasagne and beefburger.

The third round of tests revealed contamination of Bird's Eye Traditional Spaghetti Bolognese and Beef Lasagne, Taco Bell's ground beef and Brakes' spicy minced beef skewer.

Furniture retailer Ikea also withdrew wiener sausages in the UK last month after tests found "indications" of horsemeat, and it also withdrew a batch of its traditional meatballs.

The company said it was removing the sausages from sale in Britain, France, Spain, Ireland and Portugal after tests confirmed "a few indications of horse meat".

Today Tesco announced a fourth of its brands had tested positive for horsemeat

Tesco has withdrawn its 'Tesco Simply Roast Meatloaf' from sale after it tested positive for between two and five per cent horsemeat. It is the fourth Tesco-branded product to test positive for horsemeat.

Tim J Smith, Tesco Group Technical Director, said: "Today we have withdrawn from sale a product which has tested positive for between two and five percent horsemeat.

"The product is a frozen Tesco Simply Roast Meatloaf 600g. The product tested was manufactured between October 2012 and January 2013 at Eurostock in Craigavon, Northern Ireland.

"Tests on 15 other lines from the same manufacturing site were clear of horsemeat. Our investigation to thoroughly understand the source of the contamination has started and we will complete our investigation before deciding whether to continue using the supplier.

"As part of our new DNA testing programme we have now tested more than 500 products identified as being most at risk of containing horsemeat. This is the fourth Tesco-branded product to have tested positive.

"We are very sorry that we have had a further product which has failed to meet the high standards we and our customers expect."
