FDA Detention Testing for Processed & Packaged Foods
Imported processed and packaged foods are detained for pesticides, pathogens, undeclared colors, and labeling violations. Here's why FDA holds these shipments, which import alerts apply, and what testing involves.
The Short Version
Why Processed & Packaged Foods Shipments Get Detained
Processed and packaged foods face a wide mix of charges — pesticide residues, Salmonella, undeclared colors and additives, and labeling failures. Because this category spans canned, jarred, frozen, dried, and prepared products, the detention reasons are broad. Pesticide residues carry over from raw ingredients, pathogens like Salmonella appear in many product types, and processed foods frequently draw undeclared-color, additive, and allergen-labeling charges. The specific charge on the notice — and whether it's a contaminant or a labeling issue — determines whether the answer is testing, corrected labeling, or both.
The Alerts That Apply

What Processed & Packaged Foods Gets Charged For
- Pesticide Residues
- Residues carried over from raw ingredients into processed forms, above U.S. tolerances or from unapproved pesticides.
- Salmonella
- A zero-tolerance pathogen charge across many processed food types, especially those with at-risk ingredients.
- Undeclared Colors & Additives
- Non-permitted or undeclared color additives and other additives — adulteration or misbranding depending on the specifics.
- Allergen & Labeling Failures
- Undeclared major allergens, non-compliant Nutrition Facts, or missing English labeling.
- Filth & Sanitation
- Filth or evidence of insanitary manufacturing conditions in prepared products.
- Additive Violations
- Use of food additives not permitted for that use, or above allowed levels.
The Testing
What Processed & Packaged Foods Testing Involves
-
Representative Sampling
A trained sampler collects representative samples of the detained product under documented custody, accounting for how the product is packaged and lot-coded.
-
Analyte-Matched Analysis
The charge dictates the method: multi-residue pesticide screening, microbiological culture for Salmonella, color-additive or additive analysis, at an appropriately accredited (often LAAF) lab.
-
Testing or Labeling — or Both
For contaminant charges, results go into an analytical package to FDA via ITACS. For labeling charges, corrected labeling or a reconditioning plan may be the path — sometimes alongside testing.
Read the charge carefully — it may be labeling, not contamination. Processed foods draw both kinds. A labeling issue may be correctable, while a contaminant charge points to testing. See the illegal/undeclared colors alert and the full directory.
Be Realistic
Honest Notes on Processed & Packaged Foods Detentions
Set expectations honestly
- Not every charge is a testing charge. Labeling and allergen issues aren't solved by lab results — they may need corrected labeling or reconditioning instead.
- A residue or pathogen that's present can't be removed. Testing confirms rather than clears a true contaminant; it demonstrates compliance only where the product is genuinely within limits.
- Undeclared allergens are serious. An undeclared major allergen is a significant misbranding charge and a safety issue, not a paperwork technicality.
- Release isn't removal. Clearing one shipment doesn't lift an alert on the firm or country; that's a separate removal petition.
- No guaranteed outcome. We coordinate the testing that applies and can flag when labeling is the real fix — but FDA decides admissibility.
