Rag bologna is a long stick, or "chub", of high-fat bologna native to West Tennessee and its surrounding area, unavailable elsewhere. It is traditionally sold wrapped in a cloth rag, and has a higher content of filler than that of regular bologna. Milk solids, flour, cereal, and spices are added during processing, and the roll of bologna is bathed inlactic acid before being coated inparaffin wax. It is generally eaten on white bread with mustard and pickles, but is also a staple of family gatherings, where thick slices are smoked and barbecued along with other meats.[10] InNewfoundland andAtlantic Canada, a type of rag bologna referred to as "wax" bologna is sliced thickly and fried, which is referred to as "Newfie steak".[11]

Ring bologna is much smaller in diameter than standard bologna. It is better suited for slicing and serving on crackers, either as a snack orhors d'oeuvre. It is generally sold as an entire link rather than sliced. The link is arranged as a semicircle or "ring" when prepared for sale (hence the name).[12] Pickled bologna is usually made from ring bologna soaked in vinegar and typicalpickling spices.[13]
InEngland,Ireland and alsoWestern Australia, a polony is a finely ground pork-and-beef sausage. The name, likely derived from "Bologna", has been in use since the 17th century. The modern product is usually cooked in a red or orange skin and is served as cold slices.[14] In England polony can also be used for the pork sausage instead of bologna.[2][15]
InScotland, polony is a finely ground seasoned cured pork sausage often eaten in a roll, most commonly with afried egg, or as part of afull breakfast. It is cooked in a red skin, served in slices by butcher shops, and fried or grilled before eating. It is particularly popular inDundee and thenorth east of Scotland generally.[16][17]
InNew Zealand, polony is a type ofcocktail sausage with pink or red artificially-coloured skin similar to, but much smaller than, asaveloy. Miniature polonies in New Zealand are called "Cheerios" and often are eaten boiled with tomato sauce. In New Zealand, polony is also called "Luncheon Sausage" or simply "Luncheon".[18]
South African polony is similar to bologna in constitution and appearance, and is typically inexpensive. Large-diameter (artificially coloured) pink polonies are called "French polony", with thinner rolls referred to simply as "polony". Garlic polony is also widely available.[19]
In 2018 a South African factory that produced polony and other processed meats was associated witha listeriosis outbreak that killed approximately 216 people and sickened a further thousand.[20]
Various vegetarian and vegan versions of bologna are available. A typical UK recipe usessoy andwheat protein in place of lean meat andpalm oil instead of fat together with starch,carrageenan, and flavorings. It can be eaten cold or cooked in the same ways as traditional bologna.[21]
