The “Abbott Farm site,” now known as the Abbott Farm National Landmark, is known for its unique and abundant artifact assemblages from presumed Middle Woodland contexts. Several researchers attributed the presence of large quantities of argillite raw material, argillite and chert blades and blade caches, cut and uncut mica, and aberrant zone-decorated ceramics to either Hopewellian manifestations or to the Abbott Farm's role in the regional redistribution of argillite. On the basis of a cultural resource survey conducted by Louis Berger and Associates prior to the proposed construction of I-195 and I-295 and New Jersey Routes 29 and 129, a specialized economic adaptation focused upon the intensive procurement, processing, and storage of anadromous fish, especially sturgeon, is hypothesized.

Shiga toxin-producing Escherichia coli O157:H7 is a food-borne pathogen and the major cause of hemorrhagic colitis. Pseudomonas is the genus most frequent psychrotrophic spoilage microorganisms present in milk. Two-species bacterial systems with E. coli O157:H7, non-pathogenic E. coli, and P. fluorescens in skimmed milk at 7, 13, 19, or 25 °C were studied. Bacterial interactions were modelled after applying a Bayesian approach. No direct correlation between P. fluorescens’s growth rate and its effect on the maximum population densities of E. coli species was found. The results show the complexity of the interactions between two species in a food model. The use of natural microbiota members to control foodborne pathogens could be useful to improve food safety during the processing and storage of refrigerated foods.
