No, they don't. What people think the FDA does and what it really does in general are extremely different. There's a very readable paper here [1] precisely on FDA handling of food imports - that is, if for some reason, you don't choose to believe random internet guy insisting everything most people think they know about a topic is wrong. I don't think it's very purposeful for me to just rephrase the paper when you can read it yourself and get all the details. But, if nothing else, I'll at least quote the lead sentence of the background section:
---
"The FDA’s overall foods program is distinct in several respects from the agency’s other public health regulatory program areas. First—with the exception of food and color additive approvals and premarket notification for certain foods—foods under FDA jurisdiction, whether produced within or outside the United States, do not require premarket approval. Thus, the foods program overall is generally a postmarket program."
---
The FDA does spot testing of high risk foods but otherwise relies primarily on corporations to simply promise that they're following the regulations that the FDA publishes. That's how you get things like lead in apple sauce - it's not something the FDA is going to be checking for. By contrast, they would likely test something like chicken, coming from a region that had a recent bird flu outbreak, for contamination.
