Now keep it safe: three things
- Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
- Save this receipt to your camera roll.
Keep the receipt file too. The image is a handy copy; checking needs the file.
- Email it to yourself.Email it to myself

How to keep notes that hold up
Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.
- Write it down straight away, on paper or in the box on a step.
- Put the date, time and place at the top, and who you spoke to.
- Use their words where you can; separate what you saw from what you were told.
- Sign or initial a paper note, photograph it and add the photo.
- Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

Record doses and when animals can be sold
A farm sold an animal with drug traces above the allowed level. Treatment records lacked key dose and hold-time details, and no system held treated animals back. The FDA sent a warning letter; stronger action was only threatened.
Regulator warning letter; no later enforcement outcome supplied.

Log each dose before an animal leaves
A calf was sold and killed before the drug's waiting time had passed. Doses and the illness treated were not logged. The FDA sent a warning letter and said no reply had yet followed the inspection.
The source is a warning letter, which records the regulator’s findings at that time.

Write the dose given not the usual dose
Drug traces in an animal exceeded the allowed limit. The farm's records often lacked the dose or how it was given, and clashed with the owner's account. The FDA sent a warning letter and asked for a reply.

Check the prescribed wait against the shipping date
A cow was shipped after 20 days when the vet had prescribed a 21-day wait. Key treatment details and a drug stock list were missing. The FDA sent a warning letter; no reply to the inspection had yet been received.
This is a regulator warning letter, not a final court judgment.

Record each dose before the animals leave
Inspectors found no calf drug logs and key gaps in cattle drug records. The food watchdog sent a warning letter and gave 15 working days to reply. It warned that animals could be seized or work stopped by court order.
This was a regulator warning letter; the listed possible enforcement steps were not reported as completed.

Proves / Doesn’t prove
Proves
A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.
Doesn’t prove
It does not prove the dose was actually given, that the animal ID is right, that the withdrawal time was observed, who wrote the entry, or that the record meets any scheme or regulator rule.
This cannot establish treatment, a correct animal ID, an observed withdrawal period or food safety.
These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.

What should a withdrawal period record contain?
In the UK: product name, date of administration, quantity, withdrawal period and animal ID, recorded at the time of administration. FDA letters also cite missing route, condition treated, treatment days, who gave it, and milk and meat withhold dates.
Source summary as of October 30, 2026. Check the current source and its scope.
Context for this answerHow long do I keep medicine records?
UK: at least five years after the medicine was given or disposed of, even if the animal has gone. US vet extra-label records: 2 years or longer if state law says so. VFD copies: 2 years.
Source summary as of October 30, 2026. Check the current source and its scope.
Context for this answerCan my records be electronic?
UK regulations set no format. For US VFD orders, client and distributor copies may be electronic. Check your processor, scheme and state rules, as they may ask for more.

Context for this answerDoes a time receipt prove the withdrawal period was followed?
A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.
What happens if an animal goes to slaughter inside the withdrawal time?
In the FDA letters, tissue testing found residues above tolerance, the food was called adulterated, and the farm got a warning letter with 15 working days to respond.
Source summary as of October 30, 2026. Check the current source and its scope.
Context for this answerDoes extra-label use change the withdrawal time?
Yes. FDA letters treat extra-label use without vet supervision as a violation, and say accurate dose records help decide whether a longer withdrawal is needed. Ask your vet for the time to use.
