Are FDA food recalls slow? Or are the FDA simply overwhelmed?
FDA isn't overwhelmed from the perspective of incident response, it just doesn't use it's enforcement tools until someone actually gets sick. As an industry person I appreciate that they don't bring the hammer when there's a conversation to be had (e.g. we found listeria in your drain, I don't think that's reason for recall unless you find it in the product), but when you see warning letters about plants full of rotten food and overwhelming pest issues, it's clear that they aren't willing to actually enforce with teeth until the public makes them when someone gets sick.
FDA is overwhelmed by the amount of inspection activity required by FSMA, but again, these activities have nothing to do with enforcement, which has been a problem for years.
