摘要：
A method for determining the presence or absence of contaminating bacteria in a packaged food sample includes storing food in a package having as a lining a polymeric composition, said composition preferably being permeable to at least one gas selected from the group consisting of carbon dioxide and sulfur dioxide and containing an indicator for detecting the presence or abscence of the gas; the indicator being polymerized or dispersed throughout the polymeric composition or coated onto the polymeric composition.
