By the 1950s, pre-sliced and packaged deli meat was hailed as a time-saving invention for "homemakers," and bologna sandwiches were packed into millions of lunch boxes and bags. Then, in 1970s, Oscar Mayer had success with its vacuum sealed-packaging, and it began selling as much bologna as it did hot dogs with its famous jingle. At the same time, Oscar Meyer introduced a line of various deli meats - one of which was olive loaf: a bologna-like sausage studded with sliced pimento-stuffed olives.
The recall arises from complaints about undeclared ingredients in Gaiser's bologna, prompting an investigation by FSIS that discovered mislabeling of meat types.
Fried bologna sandwiches, especially popular in the South, bring a nostalgic flavor while introducing modern culinary creativity, emphasizing both texture and taste in bologna’s crispy edges.
