What's in a burger?

In an attempt to confirm the presence or absence of central nervous tissue in commercially prepared beefburgers, four burgers were processed and stained using routine histological laboratory techniques. Constituent parts of the burgers could be identified readily. In this small sample no central nervous tissue was found. There is currently considerable general interest in the contents of foodstuffs, particularly now that certain specified bovine offals as well as central nervous tissue have been banned from human consumption. Conventional histological techniques may be of value in analysing the ingredients of beef products.
