Food fraud is real, but the evidence does not show that fake food is “everywhere” in U.S. grocery stores. The FDA documents deliberate substitutions, dilution, mislabeling and short-weighting in several food categories, while warning that fraud is difficult to measure. Recent FDA findings identify problems in targeted samples—not the share of all products on shelves. For shoppers, the practical questions are what a label promises, what regulators have actually found, and when to report a concern.
What does “fake food” mean?
The U.S. Food and Drug Administration calls intentional food substitution or adulteration for financial gain economically motivated adulteration (EMA). It can mean leaving out, removing or replacing a valuable ingredient, or adding a cheaper substance to cut costs or make a product seem more valuable. The harm may be economic, but it can also be a health risk: FDA cites lead poisoning from adulterated spices and allergic reactions when an undisclosed allergen is substituted. FDA: Economically Motivated Adulteration (Food Fraud)
Is my food fake? What FDA examples show—and what they don’t
FDA documents fraud patterns involving honey and maple syrup diluted with cheaper sweeteners; extra-virgin olive oil mixed with cheaper vegetable oil; lower-value fish sold as a more expensive species; juice containing undeclared cheaper ingredients; and spices bulked up with plant material or colored with industrial dyes. These are known methods and documented cases, not proof that every item in those categories—or grocery shelves generally—is fraudulent. FDA says the frequency and economic impact are hard to estimate because fraud is intended to evade detection. FDA’s food fraud overview

| Food and assignment | FDA finding | How to interpret it |
|---|---|---|
| Honey, FY 2025 sampling; FDA report published 2026 | 4 of 102 samples were violative: two domestic and two imported. | FDA says the assignment was not designed for statistical comparison; the results cannot establish violation rates by country of origin or for all honey sold in the United States. FDA FY25 honey sampling |
| Imported frozen seafood, 2022–2024 short-weight assignment; FDA report published 2025 | 10 of 28 retail samples were violative. Reported short weight ranged from 2.3% to 9.9%; FDA refused the violative shipments entry. | This was a targeted assignment, not a market-wide survey of frozen seafood. It does not establish how common short-weighting is across products sold in stores. FDA imported frozen seafood short-weight report |
How can I tell if food is adulterated?
There is no general household test established by the reviewed official guidance for detecting food fraud. Authenticity is often assessed through regulatory or laboratory methods, including analytical chemistry and DNA sequencing. A suspicious appearance or an unusual taste may justify asking the retailer or reporting a concern, but it does not by itself prove adulteration. FDA food fraud overview
Is the fish I bought really what the label says?
Separate the claims on seafood packaging rather than treating them as one question: species, geographic origin, production method and net weight are different things to verify. DNA sequencing can help identify species substitution, but it does not establish the product’s origin or whether the declared package weight is accurate. FDA food fraud overview

- IDENTIFY WHAT FOODS & DRINKS MAY BE CAUSING INTOLERANCE SYMPTOMS. Gluten and lactose intolerances occur when the digestive system struggles to process foods within those categories like milk and bread, but these intolerances can happen with any food or drink too. If your food intolerances aren’t handled properly, symptoms like acid reflux, constipation, diarrhea, headaches, and weight gain can occur.
- TESTS 1030 FOOD & BEVERAGE ITEMS. Your hair sample is compared against 30 food and drink categories, including acidity regulators, anti-caking agents, beverages, dairy, emulsifiers, fats, flavor enhancers, food dyes, fruits, grains, herbs, legumes, modified starches, mushrooms, nuts, preservatives, processing aids, proteins, seafood, seasonings, spices, stabilizers, superfoods, sweeteners, thickeners, and vegetables.
- NON-INVASIVE HAIR SAMPLE COLLECTION WITH FAST RESULTS. 1) Register your test kit on our 5Strands website or mobile app. 2) Collect 10-15 strands of hair from anywhere on your body. 3) Mail the sample to our certified U.S. lab with the included shipping materials. 4) We’ll send the results to your email and mobile app within 4 days of receiving your hair sample.
- CLEAR ANSWERS TO START AN ELIMINATION DIET. Each food item is categorized by 4 response levels so you have a concrete starting point to eliminate trigger foods, consume mid-level food triggers in moderation, and keep safe-listed foods in your current diet. Consistent implementation of your results gives your gut microbiome the space to rebalance, promoting proper digestion while alleviating symptoms.
- INDEPENDENTLY VALIDATED & PHYSICIAN RECOMMENDED. 5Strands is the only food intolerance test of its kind supported by independent third-party research. Every sample goes through a double-pass process in our U.S. lab to ensure accuracy, and our testing has helped over 345,000 people and pets uncover their food intolerances.
Check origin claims in context
USDA Country of Origin Labeling (COOL) covers certain foods, including wild and farm-raised fish and shellfish. Origin information may appear on labels, signs, stickers or other visible formats, and the rules have exceptions. Missing origin information alone is not proof of fraud: first check whether the product is covered and how the applicable rule permits the information to be displayed. USDA AMS: Country of Origin Labeling
Check package weight separately
If you are concerned a package is short-weighted, a digital kitchen scale can help you weigh the food at home and compare it with the amount declared on the package. Account for packaging and any declared net-weight conventions when making that comparison. A scale cannot identify an adulterant, verify the fish species or prove why a weight differs; FDA’s targeted seafood finding supports checking weight, not treating a home measurement as proof of fraud.
