Microbial Spoilage Jeopardy Template

Meat	Poultry	Seafood	Milk/Dairy	Fruit/Vegetables
100 hide, hooves, hair, GI tract Origins	100 skin, feathers, feet, feces Origin	100 environment, season, water temperature/quality Origin of finfish	100 soil, water, animals, plants, milking equipment, storage tanks, utensils what are the sources of spoilers	100 soil, dust, processing plants what are sources of spoilers
200 Staphylococcus, Pseudomonas, yeast and mold Key Microorganisms	200 Acinetobacter, Moraxella Key Microorganisms	200 lobster-alive until heated shrimp- die after harvest oysters- water quality origin of shellfish	200 pseudomonadacae, flavobacterium what are the key microorganisms	200 washing and air drying, canning, freezing, MAP what are some control strategies
300 Psychrotrophs Which microorganisms thrive in reduced temperatures	300 transportation, crowding, flapping of wings, poor weather What factors contribute to spoilage	300 Acetinobacter, Aeromonas, Vibrio key microorganisms	300 lactobacillus, streptococcus, klebsiella what non-spore formers are common spoilers	300 mushy consistency caused by bacterial spoilage what is soft rot
400 Muscles have higher water activity Why are muscles more susceptible for spoilage than fatty meats	400 off odor, slime, discoloration What type of spoilage does pseudomonas cause	400 harvesting methods, chilling water on ice what factors contribute to spoilage of finfish	400 acetic acid what bacteria causes a sour odor and taste in milk	400 Aspergillus, Rhizopus what microorganisms are responsible for fungal rot
500 pale, soft, exudative What is PSE meat	500 Aeromonas Which microorganism only effects leg muscle	500 break down proteins causing off odor what are capthepticlike enzymes	500 limit contamination, rapid cooling immediately after milking, maintain cold storage temperatures, keep fermented products off floor and away from walls/ventilation what are some control strategies	500 windblown sand, insect infestation, processing/handling What ways can external barriers be compromised to allow microbial spoilage
