B
Best-By Date / Use-By Date / Sell-By Date
FDA · USDADate labels on food packaging that are often confused with each other. A best-by date indicates when a product is at peak quality — not a safety deadline. A use-by date (more common on perishables) is the manufacturer's estimate of when the product is no longer at peak condition. A sell-by date is for retailers, not consumers. None of these are federally standardized safety cutoffs. In recall notices, best-by dates are used alongside lot numbers to identify affected product — a product with a best-by date outside the recalled range is not part of the recall.
C
Class I Recall
FDA · USDAThe most serious recall classification — issued when there is a reasonable probability that a product will cause serious adverse health consequences or death. Examples include foods contaminated with Listeria monocytogenes, Salmonella, or E. coli O157:H7, drugs with dangerous contamination, and products containing undeclared allergens that could trigger anaphylaxis.
Class II Recall
FDA · USDAA recall for products that may cause temporary or medically reversible adverse health consequences, or where the probability of serious harm is remote. Mislabeled medications with incorrect dosage instructions and minor contamination issues often fall here.
Class III Recall
FDA · USDAThe least urgent recall tier — for products not likely to cause any adverse health consequences. Often involves minor labeling defects, quality issues, or technical violations that do not pose a safety risk to consumers.
CPSC (Consumer Product Safety Commission)
CPSCAn independent federal agency that protects the public from unreasonable risks of injury or death associated with consumer products. CPSC oversees recalls for thousands of product types including toys, furniture, electronics, baby gear, and appliances. Consumers can report unsafe products directly to CPSC at SaferProducts.gov.
D
Date Code / Production Code
FDA · USDAA code stamped or printed on packaging that indicates when the product was manufactured. Formats vary widely by company — common formats include MMDDYY, YYMMDD, and Julian day numbers. Recall notices use date codes alongside lot numbers to narrow down affected inventory. If a recall notice lists a date code range, check the code on your product's packaging (often on the bottom of a can, the side crimp of a bag, or near the best-by date).
F
FDA (Food and Drug Administration)
FDAThe U.S. federal agency responsible for protecting public health by regulating food (excluding meat, poultry, and some egg products), prescription and over-the-counter drugs, medical devices, cosmetics, and tobacco products. The FDA oversees food safety recalls through CFSAN and drug recalls through CDER.
Food Safety Modernization Act (FSMA)
FDAA landmark 2011 federal law that significantly expanded FDA authority over food safety. Before FSMA, the FDA could only request voluntary food recalls for most products. FSMA gave the FDA mandatory recall authority, required food facilities to implement preventive controls, and increased oversight of imported food. FSMA is why you may see an FDA food recall that the company did not initiate — the agency can now order a recall if a company refuses to act voluntarily.
G
Good Manufacturing Practice (GMP)
FDAA set of FDA regulations — formally called Current Good Manufacturing Practice (cGMP) — that govern how food, drugs, medical devices, and dietary supplements must be produced, tested, and controlled. GMP violations are a common trigger for drug recalls. When FDA inspects a manufacturing facility and finds processes that don't meet GMP standards, it may request a recall even before a specific defective product is identified, because the conditions create unacceptable contamination risk.
J
Julian Date
FDA · USDAA date format that represents the day of the year as a number from 001 to 365 (or 366 in a leap year). Julian date 047 means the 47th day of the year, or February 16. Julian dates appear on some commercial and pharmaceutical packaging, particularly on products manufactured for industrial or institutional use. If a recall notice references a Julian date, convert it by counting forward from January 1.
L
Lot Number
FDA · USDAA code printed on food and medication packaging that identifies the specific production batch. When a recall is issued, it lists the exact lot numbers affected — items from other batches may be safe. Always check the lot number on your product against the recall notice before discarding or returning it.
M
Market Withdrawal
FDAWhen a company removes a product from distribution or corrects a minor problem that does not constitute a legal violation requiring a formal recall. Market withdrawals involve no significant hazard to health — for example, minor contamination that would not require regulatory action, or product removed due to tampering with no confirmed health risk.
MedWatch
FDAThe FDA's safety information and adverse event reporting program. Healthcare providers and consumers can use MedWatch to report serious side effects, product quality problems, and unsafe products to the FDA. Reports filed through MedWatch (available at fda.gov/safety/medwatch or by calling 1-800-FDA-1088) may trigger FDA investigations that lead to recalls. MedWatch is also the source for FDA safety alerts and notices.
N
NDC (National Drug Code)
FDAA standardized 10-digit identifier unique to each pharmaceutical product, manufacturer, and package configuration in the U.S. The format is XXXXX-XXXX-XX (labeler code, product code, package code). Drug recall notices frequently list affected NDCs to precisely identify which products are recalled — a specific strength, dosage form, and package size, not an entire drug class. Your medication bottle or blister pack typically displays the NDC, making it a precise way to check whether your prescription is affected.
NHTSA (National Highway Traffic Safety Administration)
NHTSAThe federal agency within the Department of Transportation responsible for vehicle and road safety. NHTSA issues vehicle safety recall campaigns, sets federal motor vehicle safety standards, investigates vehicle defects, and maintains the national recall database. All NHTSA recall repairs are performed free of charge at any authorized dealership, regardless of the vehicle's age or mileage.
NHTSA Campaign Number
NHTSAThe unique identifier assigned to each vehicle recall campaign by NHTSA, formatted as YYVNNNNN (e.g., 23V045000 — year 2023, vehicle recall, sequence 045000). You can search by campaign number on NHTSA.gov to find full recall details and determine if your specific vehicle is included.
P
Park-It Warning
NHTSAAn NHTSA advisory, issued alongside some serious vehicle safety recalls, recommending that owners park their vehicle outdoors and away from enclosed structures — garages, houses, fences — until the recall repair is completed. Park-it warnings indicate an elevated risk of vehicle fire, typically involving battery failures. They are rare and reserved for the most severe fire hazards. If your vehicle has an active park-it advisory, do not park it in an enclosed garage. Contact your dealer immediately to discuss available options.
R
Ready-to-Eat (RTE)
FDA · USDAFood intended to be consumed without further cooking, heating, or preparation that would eliminate pathogens. Examples include deli meats, hot dogs, smoked fish, soft cheeses, bagged salads, cut fruit, and cooked rotisserie chicken. Ready-to-eat foods carry a higher risk from Listeria contamination than raw foods because there is no kill step before consumption. Most Listeria recalls involve RTE products and are classified Class I.
Recall Completion Rate
NHTSA · All agenciesThe percentage of recalled products that have received the required remedy — repaired, replaced, or refunded — out of all products covered by the recall. Vehicle recall completion rates are tracked by NHTSA and typically run 70–75%, meaning roughly one in four recalled vehicles is never fixed. Food and consumer product recall completion rates are generally lower and harder to measure because there is no direct owner notification system.
Recall Number
FDA · USDA · CPSCThe unique identifier assigned to each recall by the issuing agency. FDA food recall numbers use formats like Z-XXXX-XXXX (food) or D-XXXX-XX (drugs). USDA FSIS recalls use a RECALL-XXX-XXXX format. CPSC recalls use a YY-XXX format (e.g., 24-123 for a 2024 recall). NHTSA uses NHTSA Campaign Numbers instead. Recall numbers can be used to look up the original notice and current status directly on the agency's website.
Recall Termination
FDA · USDAA formal determination that a recall is complete and no further action is required. The FDA or USDA issues a termination letter when it is satisfied that all reasonably possible efforts have been made to remove affected product from commerce. Recall termination does not mean the recalled product was found to be safe — it means the remediation process is considered complete. NHTSA vehicle recalls do not have a formal termination process and technically remain open until all affected vehicles receive the repair.
Recalling Firm
All agenciesThe company responsible for conducting the recall — typically the manufacturer, importer, or distributor of the affected product. The recalling firm is obligated to notify consumers, retailers, and distributors, and to provide the remedy (refund, repair, or replacement).
Remedy
All agenciesThe corrective action offered to consumers who own a recalled product. Common remedies include a full refund (most common for food, medications, and consumer products), free repair (standard for vehicle recalls), a replacement product, or a rebate toward a new purchase. For vehicle recalls, dealers are legally required to perform the repair at no charge. For food and consumer products, most retailers will accept returns without a receipt.
S
SaferProducts.gov
CPSCThe CPSC's public consumer product safety database where consumers and healthcare providers can report unsafe products and injuries. Reports are reviewed by CPSC staff and can lead to investigations and recalls. Unlike SaferProducts.gov, CPSC.gov lists only formally announced recalls — SaferProducts.gov captures incident reports that may predate a recall. It also functions as a product registration portal for some juvenile product categories.
Safety Alert
FDA · CPSC · NHTSAA public notification about a product that may pose a hazard, issued before or instead of a formal recall. Safety alerts may advise consumers to stop using a product while an investigation is underway, or provide precautionary guidance when the full scope of a hazard has not yet been determined.
Service Campaign / Technical Service Campaign
NHTSAAn NHTSA action that is distinct from a mandatory safety recall. Service campaigns address defects or non-conformities that do not pose a safety risk — cosmetic issues, software glitches with no safety impact, or voluntary parts replacement programs initiated by a manufacturer. Unlike safety recalls, service campaigns are not legally required and may not be free. If your vehicle is involved in a service campaign rather than a safety recall, read the notice carefully to understand your rights and whether the repair is at your expense.
T
Technical Service Bulletin (TSB)
NHTSAA notice issued by a vehicle manufacturer to dealerships describing a known issue and the recommended repair procedure. TSBs are NOT safety recalls — they do not require manufacturers to notify owners or perform repairs for free. However, a TSB may later be escalated to a recall if NHTSA determines the issue poses a safety risk.
U
Undeclared Allergen
FDA · USDAA food allergen present in a product that is not disclosed on the label. The nine major allergens regulated in the U.S. are milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. Undeclared allergen recalls are nearly always Class I (most serious) because they can trigger potentially fatal anaphylactic reactions in sensitive individuals.
UPC (Universal Product Code)
FDA · USDA · CPSCThe barcode printed on retail product packaging. Recall notices often list UPC codes to help consumers identify affected products. The 12-digit number under the barcode can be compared directly to UPCs listed in a recall notice — or scanned with a phone app — to determine if your product is included.
USDA FSIS (Food Safety and Inspection Service)
USDAThe public health agency within the U.S. Department of Agriculture responsible for ensuring that meat, poultry, siluriformes (catfish), and egg products are safe, wholesome, and accurately labeled. FSIS oversees food safety recalls for these specific product types separately from the FDA, which covers other food categories.
V
VIN (Vehicle Identification Number)
NHTSAA unique 17-character alphanumeric code assigned to every motor vehicle at manufacture. The VIN encodes the country of manufacture, manufacturer, vehicle type, model year, assembly plant, and a sequential serial number. NHTSA uses VINs to identify which specific vehicles are covered by a recall campaign. Your VIN appears on the driver's door jamb sticker, the dashboard (visible through the windshield on the driver's side), and your vehicle registration and insurance documents.
Voluntary Recall
All agenciesA recall initiated by a company without being ordered to do so by a regulatory agency. Despite the name, voluntary recalls carry the same obligations for consumer remedy as mandatory recalls. Companies typically initiate voluntary recalls after discovering a defect internally, receiving consumer complaints, or being contacted by a regulator about a potential issue.
