The Venn plot indicated that 24 sequences were common across
all time points (Fig. 4), corresponding to 20 families of bacteria existing
on the surface of vacuum packed pork throughout 21 day storage period.
Of these 20 families of bacteria, Flavobacteriaceae, Staphylococcaceae,

during the first 7 or 14 days of storage. Lactobacillaceae dominated
and played a critical role in the spoilage of meat at day 21
