Canned foods are more often prone to flat sour spoilage due to contamination by either mesophilic or thermophilic aerobic spore formers.Dextrose Tryptone Agar is a bacteriologically controlled medium for the detection and enumeration of thermophilic and mesophilic organisms in food products. Its use for routine cultural purposes is recommended by Cameron^2 and the Association of Official Analytical Chemist^3. Dextrose Tryptone Agar is also recommended by:
• Tanner^4for the examination of canned food, sugar, and starch for thermophilic bacteria of theBacillusstearo thermophilustype (i.e.flat-sourspoilage bacteria).
• The American Public Health Association^5for the enumeration of mesophilic and thermophilic aerobic bacteria in sweetening agents used in frozen dairy foods.
• The National Canners Association6 for determination of the total plate andflat-sourcount of thermophilic bacteria spores in ingredients, such as sugar and starch.
• The American Public Health Association^7for the enumeration of mesophilic organisms andflat-sourspores in sugars, starches and other complex carbohydrates; and for the enumeration offlat-sourthermophiles in cereals and cereal products, dehydrated fruits and vegetables, and spices.
• Baumgartner and Hersom^8for the examination of low and medium-acid canned food (above pH 4.5) forflat-sourthermophiles, mesophilic aerobes, and facultative anaerobesNot all products are available for sale in all territories.
