There is never a "good" time to initiate a recall. But the worst time is when you are forced to remove unsafe food from commerce and haven’t effectively planned for it.
If your food safety plan has identified critical control points and/or preventive controls per your hazard analysis, the FDA'’s Food Safety Modernization Act (FSMA) requires you to have a documented recall program.
Handling FDA and state regulatory inspections has never been easy, but at least companies knew what records they had to share and how to deliver a uniform company message by using designated plant spokespeople.
