Lot Tracking for Food & Beverage Manufacturers: What Regulators Expect and the Software That Delivers

It is 4 p.m. on a Friday when your distributor calls: a customer may have had a reaction, and they need to know whether last month's production could contain undeclared allergen from a shared line. There are two versions of the next hour. In the first, you pull your lot records, identify the three affected batches, confirm they went to two customers, and have the scope of the problem documented by 5 p.m. In the second, you have no lot-level records - so the answer is everything you made last month, every customer, every case. Same phone call, wildly different weekends.

Lot tracking is the difference between those two versions, and for food and beverage manufacturers it is not optional. Here is what regulators actually require, what your buyers now demand, and how the physical and digital halves of traceability fit together.

What Lot Tracking Actually Means

A lot is a batch of product made under essentially the same conditions - same run, same day, same ingredient set. Lot tracking has two halves. The physical half is the code itself: a printed identifier on every container and case that ties the unit in a customer's hand back to one production run. The digital half is the record trail: which supplier lots of each ingredient went into that batch, and which customers received the finished goods. Regulators call the minimum standard one-up, one-down - you can name where every input came from and where every output went. Mature lot tracking goes further: from any point, you can trace all the way back to raw materials and all the way forward to shipments, quickly.

What the FDA Expects

Start with the baseline that applies to virtually everyone: registered food facilities must keep records showing the immediate sources of their ingredients and the immediate recipients of their products. If an investigator asks where the citric acid in March's production came from and where those cases shipped, you are expected to answer from records, not memory.

Some categories go further. FDA regulations for acidified foods - the rules covering hot sauces, salsas, dressings, and pickled products - require each container to carry a permanent, visible production code identifying where and when it was packed. If you are in these categories, the lot code on the bottle is not best practice. It is the regulation.

Then there is the FSMA Food Traceability Rule, the biggest change to food recordkeeping in a generation. It applies to foods on the FDA's Food Traceability List - soft cheeses, shell eggs, nut butters, fresh produce, seafood, ready-to-eat deli salads, and more - and to products containing them in the same form. Covered businesses must assign traceability lot codes and record key data elements at each critical tracking event: receiving, transformation, and shipping. When FDA asks, those records must be produced within 24 hours. The compliance date was originally January 20, 2026 and has been extended to July 20, 2028 - which sounds like breathing room, until you read the next section.

One more reason lot codes matter regardless of category: recalls. FDA has mandatory recall authority, and the scope of any recall is defined by what you can prove. Without lot-level records, you cannot recall a batch - you recall a brand. None of this is legal advice, and requirements vary by product, so confirm the rules for your specific category. But the direction of travel is unmistakable.

Your Buyers Will Not Wait for 2028

Here is what the deadline extension did not change: retailer and distributor requirements. Walmart began enforcing its own supplier traceability program in 2025 - lot data transmitted with shipments and GS1-128 barcoded case labels - with chargebacks for non-compliant deliveries. Large distributors and grocery chains are following the same playbook, and any facility pursuing an SQF or BRC certification will be asked to demonstrate documented traceability and complete a mock recall exercise on a timer. In practice, the federal date moved to 2028; your biggest customer's date is whenever they say it is.

The Physical Half: Getting the Code On the Product

Every container needs a code, and hand-writing them stops being viable around the same time hand-filling does. Continuous inkjet (CIJ) printers are the standard answer at small-batch scale: they print lot numbers and best-by dates on glass, plastic, and metal as product moves down the line, with quick code changes between batches. Compact units like the Linx 10 were designed for exactly this job. At the case level, box printers put batch data directly on corrugate, and thermal label printers from Zebra, and Sato produce the GS1-128 case labels that retailers scan at receiving. You can compare options across our coding and marking equipment range.

A note on code format: keep it human-readable and consistent - a simple structure like a batch number plus a packed-on date serves most small manufacturers well. The format matters less than the discipline behind it: every code printed must map to a record somewhere.

The Digital Half: Software That Keeps the Thread

This is where spreadsheets quietly fail. A traceability spreadsheet depends on someone recording exactly which ingredient lots were consumed, in the middle of a production day, every single time - and then keeping one authoritative version of the file. Under the pressure of a real trace request, most spreadsheet systems produce answers in days. The FDA's rule contemplates 24 hours, and your distributor's quality team expects the same afternoon.

Manufacturing software makes lot tracking a side effect of normal work instead of a separate chore. Ingredients are received against supplier lots, batches consume those lots through your recipes automatically, finished goods get their own lot numbers, and shipments link lots to customers. The trace, in both directions, becomes a search rather than an investigation.

MRPeasy is the compliance-forward option for small and mid-size manufacturers - roughly ten to two hundred employees - with lot and expiry tracking built into receiving, production, and shipping, plus the documentation trail auditors ask for.

Katana is the approachable entry point for food, beverage, and cosmetics brands leaving spreadsheets: visual production scheduling with batch and expiry tracking, and native Shopify and QuickBooks integrations so lot records line up with orders and the books.

Run a Mock Recall This Quarter

You do not find out whether your traceability works during a real recall - you find out during a drill. Pick one lot you shipped last month. Trace it backward: which supplier lots of each ingredient went into it? Trace it forward: which customers received it, in what quantities, on which dates? Time the whole exercise. Auditors generally expect this done in hours. If it takes your team a weekend and three people, you have learned something valuable at zero cost - and you know exactly what to fix before a regulator, a buyer, or a Friday phone call tests it for real.
