The bacteria of food packaging paper and board were studied. Most of the aerobic strains were spore‐formers; members of the genus Bacillus with B. cereus group ( B. cereus, B. mycoides, B. thuringiensis ), B. polymyxa group ( B. polymyxa, B. circulans, B. macerans, B. pabuli ), B. brevis and B. licheniformis predominated. The main source of spore‐forming bacteria in paper and board was the broke (rejected paper of board, which is repulped and recycled into the process). Gram‐negative bacteria were rare in paper and board in spite of their abundance in the stock. A strain of B. pumilus forming clumping, hairy spores may be of significance in aseptic packaging.
