Answer

To determine which of the following has adopted legislation requiring mandatory labeling for all GM food, we will analyze each option provided:

1. **US Food and Drug Administration (FDA)**: The FDA does not require mandatory labeling for genetically modified (GM) foods. Instead, it has a voluntary labeling policy, meaning that manufacturers can choose to label their products if they wish, but they are not legally required to do so.

2. **European Union (EU)**: The European Union has strict regulations regarding GM foods. It mandates that all GM foods must be labeled as such. This legislation was adopted to ensure consumer awareness and safety, as many consumers prefer to avoid GM foods.

3. **Canada**: Canada does not have mandatory labeling for GM foods. Similar to the FDA, Canada has a voluntary labeling policy. While GM foods must be assessed for safety, there is no requirement for labeling them as genetically modified.

4. **Australia**: Australia also does not have mandatory labeling for GM foods. Like Canada and the US, it follows a voluntary labeling system.

Based on this analysis, the correct answer is the **European Union**, as it is the only entity among the options listed that has adopted legislation requiring mandatory labeling for all GM foods.
