Samples of southern peas [ Vigna unguiculata (L.) Walp., cv. Purple Hull Pinkeye] were obtained at critical stages in a normal harvesting, transportation, and cryogenic processing operation and microbiologically analyzed for total plate count (TPC), Enterobacteriaceae count (ENT), and yeast and mold counts. Molds were identified to genera while ENT were identified to species. Operations involving extended holding times tended to increase all counts significantly, although subsequent processing reduced these counts to an acceptable level. Predominant genera of ENT and molds appeared to be soil borne organisms such as Enterobacter agglomerans, Enterobacter cloacae, Klebsella pneumoniae, and Serratia liquefaciens, and Fusarium, Cladisporium, Alternaria, Phoma, and Aspergillus , respectively.
