Bacteria responsible for decay of precut celery ( Apium graveolens ) appear to be residents on the plants at harvest. Bacterial genera isolated from equipment in a fresh celery packinghouse were similar to those found on plants sampled at the packinghouse entrance. Population densities and array of genera were highest on unwashed plants, whereas certain genera were no longer detected on the washed plants. Fluorescent Pseudomonas spp. predominated, but strains of Pantoea agglomerans (= Erwinia herbicola ), Enterobacter agglomerans, Aeromonas, Arthrobacter , and Aureobacterium were frequently isolated. Members of the coliform group such as Citrobacter, Klebsiella , and Escherichia were rare.
