FDA Regulation:

The FDA considers Allura Red safe for consumption when used within specified limits. It mandates labeling requirements to inform consumers of its presence in food products.

EU Regulation:

The European Food Safety Authority (EFSA) also permits the use of Allura Red but has set an Acceptable Daily Intake (ADI) to limit exposure.

Health Considerations

While Allura Red is generally recognized as safe by regulatory authorities, it has been the subject of some health-related controversies:

1. Hyperactivity in Children:

Some studies suggest a possible link between synthetic dyes like Allura Red and hyperactivity in children. This has led to calls for more research and stricter regulations.

2. Allergic Reactions:

Although rare, some individuals may experience allergic reactions to Allura Red, such as hives or respiratory issues.

3. Carcinogenicity:

There have been concerns about the potential carcinogenic effects of azo dyes, including Allura Red. However, current evidence does not conclusively link it to cancer when used within regulatory limits.
