Abstract
At the time of manufacture, 74% of 27 sets of chopped liver (2 to 10 finished product units/set) collected from eight firms had aerobic plate counts (arithmetic averages) of fewer than 50,000/g, and 52% had 10,000 or fewer/g. Of the total of 209 finished product units, 57.4% were coliform-positive, but only 8.6% were Escherichia coli-positive and only one unit was Staphylococcus aureus-positive. All units were salmonellae-negative.
