Dressed, bagged whole chickens from three Oregon and several
out-of-state processors were purchased from retail markets in each
season in 1988. Birds were stored at 3°C for 6 days. Total aerobic
microorganisms, total psychrotrophic microorganisms, pseudomonads
and fluorescent pseudomonads were determined by appropriate
procedures. Total aerobic microorganisms and psychrotrophic
microorganisms...
The Hazard Analysis and Critical Control Point (HACCP) system for
studying the food preparation process was conducted in four households in an
environmentally poor urban neighborhood of Guayaquil, Ecuador. The analysis
consisted of observing all of the steps in the food preparation process, measuring

The effect of different oxygen atmospheres on growth, energy
charge and enterotoxin production of Staphylococcus aureus was
investigated. Three atmospheres, air, 5% oxygen in nitrogen and
20% oxygen in nitrogen, were tested on three strains producing
enterotoxins A, B and C. Colony forming units (CFU), dry weight,
dissolved oxygen, pH,...
