The invention generally relates to food quality indicators and, more particularly, to improved adhesive food quality indicators and their use and manufacture. The food quality indicators (FQI) of the invention are advantageously simple and low cost but sensitive devices for detecting unhealthy levels of food spoilage products in a sealed food product package. The FQI is affixed to a breathable or gas-permeable wrap around the product, and a visual indicator region in the FQI that is sensitive to the presence o f food breakdown products allows the end user, by visual observation to determine whether microbial spoilage has occurred.
