The fix was simple in theory and urgent in practice, pause the shipment, complete the director‑prescribed buyer notice, and get documented acknowledgment before any transfer. That one call saved a bad day, a possible recall, and a ding to the dairy’s reputation.
You may hear folks on the yard call this “Form 14360.” That nickname points to the actual requirement in California Food and Agricultural Code section 14360. The law says you cannot sell, consign, or otherwise dispose of treated livestock or livestock products during a drug withdrawal period unless you first notify the buyer in a form the director prescribes. In other words, notice is not optional, and it must use the official format.
If you want the specific paper to use, CDFA’s Inspection Services Division lists a form titled “IS‑513‑037, Notification Of Drug Treated Livestock.” That is the director‑prescribed vehicle producers, markets, and processors rely on to meet the section 14360 notice requirement. Many folks shorthand that as “Form 14360,” which is fine for conversation, but in your files you should reference the CDFA form name and capture timestamps for delivery and receipt.
Quick truth, the statute sets the duty, the department provides the tool, and you must prove you used it on time.
Key Takeaways
- You must notify the buyer, in writing, any time treated animals or livestock products are still inside a drug withdrawal period. Use the director‑prescribed format, not a generic note.
- CDFA provides “IS‑513‑037, Notification Of Drug Treated Livestock,” which satisfies section 14360’s format requirement when completed accurately and delivered before the transaction. Keep timestamped proof and buyer acknowledgment.
- The withdrawal period exists to keep residues out of food. Federal programs like FDA approvals, FARAD guidance, and USDA‑FSIS National Residue Program testing backstop compliance, so documentation lapses can ripple into recalls or holds.
- If the withdrawal time has fully elapsed, this specific notice is not required under section 14360. You should still keep treatment records and labels that show the interval.
- This article reflects the law as available on December 4, 2025. Always verify you are using the current CDFA form version and current code text.
Compliance note, this guide is for general information and workflow planning. It is not legal advice. For a specific situation, confirm details with your veterinarian, market operator, processor, or counsel, and check the current statute and CDFA forms.
What Section 14360 Requires, In Plain English
California’s rule is short and direct. If you, or your agent, sell or dispose of treated livestock or livestock products during the drug’s labeled or prescribed withdrawal period, you must first notify the buyer. The notice has to be in the form the director prescribes. No notice, no sale, unless that period has ended.
Two companion rules matter for your day‑to‑day operations:
- Labels must include withdrawal periods and disposal times, which is why your files need clean, complete labels and treatment logs.
- Using or administering a registered livestock drug must follow the label, including withdrawal times. That is a separate unlawful act if you miss it, and it sits next to the 14360 notice duty.
Put simply, the state expects you to treat per label or veterinary direction, hold animals or products through the entire withdrawal, and, when you must move something during that period, to disclose it in the official format before transfer.
Why Withdrawal Periods Exist, And Why Your Notice Matters
Withdrawal periods are the buffer that lets residues drop below legal tolerances. FDA sets tolerances and withdrawal times when it approves animal drugs. FARAD provides accessible tools and expert guidance to help your veterinarian and team calculate safe dates, especially for complex cases or extra‑label decisions. The USDA‑FSIS National Residue Program then verifies, through sampling at slaughter and in egg products, that the food supply stays within limits. Your records and buyer notices are the frontline that keeps you out of that spotlight.
If you ever feel unsure on the withdrawal date, ask your veterinarian to run FARAD’s Withdrawal Date Calculator for a second check, then tie that date to your shipping hold. It takes two minutes and prevents expensive surprises.
When You Must Notify, And When You Do Not
Use this quick matrix to decide if a section 14360 notice is required.
| Scenario | Is Notice Required? | Why |
| Animal or product is still inside the labeled or prescribed withdrawal time | Yes, deliver the director‑prescribed form before transfer | The statute requires buyer notice during a withdrawal period. |
| Withdrawal time has fully elapsed and records confirm it | Not required by section 14360 | The duty attaches only during the specified withdrawal period. Keep treatment files anyway. |
| Extra‑label use extends the withdrawal time | Yes, and document the extended interval source, for example FARAD or the prescribing veterinarian | Extra‑label use requires a scientifically justified extended withdrawal period, which you must follow. |
A practical tip, align your shipping calendar to the safe date, not the original treatment date. That means you schedule movement after the end date, or, if you must move earlier, you prepare and deliver the notice in advance, with explicit dates and times the buyer can act on.
How To Complete The Director‑Prescribed Notice Without Slowing The Load
You will see the CDFA form titled “IS‑513‑037, Notification Of Drug Treated Livestock.” Build this into your normal shipping packet. The fastest teams pre‑populate farm and contact sections, then fill treatment specifics case by case.
Step‑By‑Step
- Confirm the trigger
- Pull the treatment log and the label. Verify the drug, dose, route, species, treated animal IDs or lot, and the exact withdrawal period. If extra‑label use applies, attach the veterinarian’s instructions or FARAD reference.
- Calculate the safe date and time
- Count from the treatment date and time. For milk and eggs, use continuous time, not just calendar days. If any doubt remains, ask your veterinarian to cross‑check with FARAD’s calculator.
- Complete the form fields
- Drug name and active ingredient, treatment date and time, withdrawal interval, calculated end date and time, animal or product identifiers, lot or pen, and your contact information. Use plain, legible animal IDs that match eartags, pen cards, or RFID exports.
- Deliver before any disposition
- Send the notice to the buyer or receiving facility before the sale, consignment, or shipment. Electronic delivery is fine if your method captures timestamps and read receipts, and if the buyer acknowledges receipt. The statute cares about form and timing. Save the proofs.
- Record buyer acknowledgment
- Capture a signature, a read receipt, or a system log that shows delivery and acceptance. File it with the load sheet.
- Archive for audit
- Save the notice, treatment label, and logs in your compliance folder. Tie each to the lot, scale ticket, invoice, and movement record.
What Good Files Look Like
- A complete treatment log with label images, drug lot numbers, and initials of the person who administered the drug.
- A calendar or software flag that calculates the withdrawal end date and blocks shipment until cleared.
- The completed CDFA notice with a clear, legible buyer acknowledgment and a timestamp that precedes movement.
- A clean chain of documents that links animal IDs or lots to the truck, the sale, and the receiving facility.
This level of documentation is not overkill. FSIS residue sampling, including inspector‑generated sampling when animals show risk factors, is routine and well organized. Good files turn a phone call into a quick closeout instead of a drawn‑out investigation.
Sample Language You Can Use
“These animals were treated with [drug] on [date and time]. The labeled withdrawal period is [X days]. The calculated end of withdrawal is [date and time]. Until that time, these animals or derived products must not enter commerce for food. Please acknowledge receipt of this notice.”
Avoid These Common Mistakes
- Missing the exact time, not just the date. Residues care about the clock, especially for milk and eggs.
- Using a homemade notice. The law requires the director‑prescribed format, which CDFA publishes as “IS‑513‑037.” Use it.
- Delivering after the fact. Notice must precede the transfer, not follow it. Late notice does not fix the violation.
- Poor file names and scattered storage. Create a unified scheme, for example FarmID_Lot_Date_Notice.pdf, and centralize storage with access controls.
- No link between the form and the actual lot on the truck. If the notice and the load do not match, you lose the protection you think you have.
If you manage a larger operation, assign a single owner for withdrawal holds and buyer notices. One accountable person frees everyone else to focus on care, shipping, and intake.
Practical Controls That Keep You Out Of Trouble
- Calendar rules that count withdrawal days from the time on the treatment log.
- Software or spreadsheet that blocks a shipment until someone attaches the completed notice or marks the withdrawal complete.
- Labels stored with each treatment entry. Label directions matter, and state law expects you to follow them.
- A laminated load‑out checklist for drivers, lot handlers, and office staff.
- A standing contact list for your auction, market, and processor intake leads, so you can transmit the notice quickly and confirm receipt before the truck rolls.
Accountably note, on our side we care about clean, defensible workflow, so we recommend using role‑based access, timestamped email or e‑signature tools, and a single folder per load that ties together notice, invoice, scale ticket, and gate sheet. Mention us only if helpful, but the point is the discipline, not the logo.
Director‑Prescribed Notification Form Requirements
When an animal or livestock product is still inside a withdrawal period, the state expects you to use the director‑prescribed form, not a homemade memo. Think of the official form as your seatbelt, it locks in the facts a buyer needs and it proves you met your duty before any sale or transfer. Your job is to complete every required field clearly, deliver it before the transaction, and keep proof that the buyer received it.
Required Form Elements
The form is simple when your treatment files are tidy. Make sure you include these items every time.
- Drug name, active ingredient, and treatment date and time
- Withdrawal period length, plus the calculated end date and time
- Animal or product identifiers, such as eartags, lot, pen, or load sheet line numbers
- Quantity or head count that matches the shipment
- Your name, role, and contact information, and, if an agent is acting, the agent’s details
- Any extra‑label direction from a veterinarian if the interval differs from the label
- A clear statement that the animals or products remain within the withdrawal period
Tip, print or attach a label photo to the packet so the reviewer can match directions to your calculation.
Timing Of Notification
Timing is the trap that catches busy yards. Notice must reach the buyer before any sale, consignment, or transfer takes place while the withdrawal clock is still running. If you expect a same‑day sale, send the notice as soon as you schedule the load. If the withdrawal will end before delivery, update your calendar and wait to ship until after the safe time, which removes the notice requirement for that load. When in doubt, send the notice early and keep the timestamp.
Owner And Agent Duties
The statute assigns responsibility to the owner, and to the owner’s agent. That means your brand office, your market consignor, or your truck broker must all know when a withdrawal applies and who will send the form. Assign names, not job titles. Put the task on a checklist. If more than one party might act, pick one responsible person and make everyone else a backstop.
Timing And Method Of Buyer Notification
You can hand a paper form to a ring clerk, upload it to a processor portal, or email a signed PDF to a buyer. What matters is that the buyer gets it in the prescribed format before the transaction, and that you can prove the timing.
- Use email with read receipts, or a portal with automatic logs
- Capture a signature when you hand off a paper form
- Store the sent file, the timestamp, and any acknowledgment in the same folder as the load sheet
- If a sale accelerates, resend the notice and call the intake lead, then note the time and the person you spoke with
| Compliance Focus | What You Do |
| Trigger check | Confirm treatment and calculate the exact withdrawal end time. |
| Form currency | Use the current director‑prescribed form, not a template that has been altered. |
| Delivery point | Send notice before any sale, consignment, or transfer. |
| Proof | Keep timestamped evidence of delivery and buyer acknowledgment. |
Prohibited Actions During The Withdrawal Period
You cannot sell, consign, or otherwise dispose of treated livestock or treated products while the withdrawal period is active unless the buyer has been notified in the official format. You also cannot move animals in a way that turns a blind eye to the rule, for example commingling treated and untreated cattle in a single lot without disclosure.
No Sale During Withdrawal
Treat the withdrawal period as a hard stop that controls your calendar. Do not move animals or products into commerce for food until the safe time arrives. Segregate affected animals, tag them clearly, and set a visible hold date so nobody moves them by mistake. For milk or eggs, track by hour, not just by day.
Mandatory Buyer Notification
If a sale must occur while the clock is still running, you or your agent must give the buyer written notice before the transaction. Keep the language clear, list the safe time, and state the animals or products that are covered. Missing even one animal on the list can create a gap in protection.
Director‑Prescribed Notice Format
Small deviations can cause big headaches. Use the current format, keep the order of fields, and avoid editing the layout unless the department allows it. If you need language access for a buyer, provide a translated cover page, then include the official form as the controlling document.
| Requirement | Practical Tip |
| Prescribed layout | Fill the form as published, store a blank copy in your shared folder. |
| Authorized media | Ask the buyer which digital formats they accept, then stick to one method for consistency. |
| Language access | Offer a translated summary, keep the official form as the record of notice. |
| Specific facts | List drug, treatment date and time, withdrawal end time, and identifiers that match the load. |
One habit protects you every time, send the official form early, then confirm who received it and when.
Recordkeeping And Documentation Best Practices
Clean records turn a stressful inquiry into a short call. You want a reviewer to connect the dots in minutes, not hours. That means clear names, consistent storage, and automatic audit trails.
File Architecture And Naming
Use one folder per load or lot, with subfolders for Treatments, Notices, Movement, and Receipts. Name files so a new employee can understand them at a glance.
- FarmID_Lot_YYYYMMDD_TreatmentLog.pdf
- FarmID_Lot_YYYYMMDD_Notice_Signed.pdf
- FarmID_Lot_YYYYMMDD_ScaleTicket.jpg
- FarmID_Lot_YYYYMMDD_Invoice.pdf
Tie animal IDs in the treatment log to the load sheet line numbers. If you use RFID or an auction manifest, export a copy and place it in the Movement subfolder.
Digital Safeguards
Use role‑based access so only your compliance lead and operations managers can change files. Turn on version history, keep encrypted backups, and prevent local downloads on shared devices. If you email forms, store the sent email as a PDF with the timestamp visible. For portals, download the delivery receipt or screenshot the confirmation screen.
Audit Trail And Reconciliations
Every quarter, reconcile your treatments against shipments and notices. Pull a list of all treatments within the last 90 days, then verify that each treatment either reached a safe date before shipment, or had a notice on file. Document gaps, fix them within 30 days, and record what changed.
| Control | Frequency | Owner | Evidence |
| Treatment to shipment reconciliation | Quarterly | Compliance lead | Checklist and corrected files |
| Form currency check | Semi‑annual | Office manager | Screenshot of current official form |
| Role‑based access review | Quarterly | IT or systems lead | Access report and sign‑off |
| Random file audit, five loads | Monthly | Plant or yard foreman | Audit log with findings and fixes |
A tidy audit trail is a gift to your future self. Keep it simple, repeatable, and boring.
Compliance Risks And Potential Penalties
A single missed notice can snowball into fines, product holds, and market bans. If residues enter commerce, you can face destruction orders, recalls, and civil exposure. Repeated lapses can trigger steeper penalties and, in serious cases, criminal referral. The biggest preventable risks are late notice, wrong format, and mismatched animals on the form. You control all three with checklists, training, and clear ownership of the task.
A single missed buyer notice during a withdrawal period can result in penalties and costly remediation.
Practical Steps For Producers And Sellers
Here is a field‑tested flow you can implement this week.
- Map the workflow
- Draw the path from treatment to sale, mark where withdrawal checks and notices occur, and assign named owners.
- Build the packet
- Store a blank copy of the official notice, plus a short cheat sheet with the calculation method, in a shared folder everyone can open.
- Calculate and flag
- Record treatment date and time, then calculate the safe time. Add a calendar hold that blocks market scheduling until that time.
- Prepare the form
- Fill every field. Attach a label photo or a scan of veterinary directions if the interval differs from the label.
- Deliver and confirm
- Send the notice before the sale or consignment. Capture a signature, read receipt, or portal confirmation. Note the person and time.
- Ship with confidence
- Carry a printed copy of the notice with the load. Make sure the driver knows which pens or lots it covers.
- Archive and reconcile
- File the signed notice, then reconcile treatments and shipments monthly so you catch any misses quickly.

Role Of Veterinarians And Pharmacists In Compliance
Your veterinarian and pharmacist are key partners, not just suppliers. They document treatments, specify withdrawal periods, and help you calculate safe dates. When they provide precise labels and written directions, your team can complete buyer notices quickly and correctly.
Prescribing And Dispensing Oversight
Make your clinic and pharmacy part of the control system.
- Connect each drug to a documented withdrawal interval, labeled or prescribed, and store that with the treatment record.
- Require clear labels and written directions, including species, dose, route, and withdrawal time.
- Audit dispensing against inventory and treatment logs each quarter.
- If extra‑label use is necessary, document the extended interval and attach it to the file.
- Train staff on how to read labels and where to find the withdrawal information fast.
Buyer Notification Procedures
Set up a simple handoff from animal care to shipping. As soon as a treatment is recorded, flag the animal or lot in your system. If an animal might move before the safe time, auto‑generate a task for the office to prepare the buyer notice. Your veterinarian can help verify calculations in complicated cases, for example repeated doses or changes in route.
Coordination With Processors, Markets, And Auctions
Your notice matters only if the receiving party has it before the transaction. That calls for routine coordination with intake teams.
Align sales with intake. Send the notice data ahead of the truck, segregate lots, and confirm receipt at the gate.
- Pre‑arrival, transmit the notice and a list of IDs or counts, then ask for staging instructions.
- On arrival, reconcile animals to the notice, confirm the safe time, and apply any facility tags or marks.
- Keep commingling controls tight. Clear pen signs and load sheets prevent mistakes.
- After intake, save the time‑stamped acknowledgment in your load folder.
Updates And The 1988 Amendment History
The core rule has been in place since the 1988 amendment sharpened the duty to notify buyers before any sale or disposal during a withdrawal period. The director retains authority to prescribe the form. The practical takeaway for you, train agents, embed notice into point‑of‑sale workflows, and track retention so you can prove what you did and when you did it.
Verifying Current Legal Text And Official Sources
Laws and forms get updated. Set a quick calendar routine so you always work from the current version.
- Check the current text of section 14360 on the state’s legislative site each season.
- Confirm you are using the latest director‑prescribed form. Replace older templates in your shared folders.
- If you subscribe to a legal service, review annotations and cross‑references for any changes that affect timing or content.
- Keep a short log in your compliance binder that lists the check date, the form version, and your initials.
Your signature is the last step. Make sure the form and the rule you rely on are current on the day you use them.
Related State And Federal Regulations To Consider
Section 14360 lives inside a larger residue control system. Use this table to keep the moving parts straight.
| Authority | What It Covers | Why It Matters To You |
| California Food and Agricultural Code, livestock drugs | State rules for sale, use, labeling, and buyer notice during withdrawal | Sets your day‑to‑day obligations for treatments and buyer notification |
| FDA approvals and labeling, AMDUCA limits | Federal tolerances, label directions, and extra‑label boundaries | Drives the withdrawal times you must follow and document |
| FARAD guidance and tools | Evidence‑based withdrawal calculations and support | Helps your veterinarian calculate safe times in complex cases |
| USDA‑FSIS National Residue Program | Sampling and enforcement at slaughter and in egg products | Confirms the system works, and investigates when it does not |
Keep your program aligned across these sources. That way, your files tell one consistent story from treatment to sale.
Frequently Asked Questions
Do I always need to send the notice if an animal was treated?
No, only when the animal or product is still inside the stated withdrawal period at the time of sale or disposal. If the safe time has passed, the section 14360 notice is not required, although you should keep the treatment record.
Can I use an electronic form and signature?
Yes, electronic delivery and e‑signatures are fine when the format matches the director‑prescribed form and you keep timestamped proof of delivery and buyer acknowledgment.
What if the buyer refuses to acknowledge the notice?
Do not proceed with the sale until you have confirmation that the buyer received the notice. If you cannot obtain acknowledgment, hold the animals until the withdrawal period ends.
How do I handle a mixed group where only some animals were treated?
Identify each treated animal on the form and segregate them physically. Consider separate loads or clear pen signs so the notice and the shipment match exactly.
How long should I keep the records?
Keep notices and supporting files for your standard retention period, and no less than the period your market or processor requires. Many producers choose at least three years, more if contracts or audits require it.
What if the withdrawal ends during transit?
If the sale or transfer occurs while the withdrawal is still active, send the notice before the truck leaves. You can add a note that the withdrawal ends at a specific time during transit.
Does this apply to milk and eggs?
Yes, the duty covers livestock products as well. Track by hour for continuous products, and document the exact safe time.
Who is responsible, the owner or the agent?
Both can be responsible. Assign one person to send the notice, and train any agents who might act on your behalf.
What if the veterinarian changes the dosing schedule?
Update the withdrawal calculation. If the revised plan extends the interval, send a new notice or delay the sale until the new safe time.
Can I combine multiple drugs on one notice?
You can, if the form allows and your identifiers are clear. Use the longest applicable withdrawal time, and list the drugs and treatment times separately.
Conclusion
You keep animals healthy, protect the food supply, and avoid penalties when you treat, calculate the safe time, and notify buyers in the official format whenever the clock is still running. Build a simple packet, assign one person to own the task, and keep timestamped proof. If you want a ready‑to‑use folder structure, a one‑page checklist, and a short training script for your crew, we can share the templates we use with firms and producers every week. Either way, you now have a clear, practical process you can run with confidence, from the first dose to the final handshake.
