IDEXX Snap Test
Consumers are increasingly concerned about antibiotic residues in milk. Give them the assurance of the highest product quality by relying on the most thorough rapid test on the market: the SNAP test from idexx.
When to test for antibiotic residue contamination
Keeping antibiotics out of the milk supply is essential to ensure product safety, protect against bacteria resistance, and maintain consumer confidence.
There are three essential residue-testing check points:
Before treated cows return to the milking line.
Testing is essential because antibiotic withhold times can vary, for example:
- Older cows retain antibiotics longer than younger cows and many times longer than the stated withhold times.
- If a cow is treated “extra label,” the cow typically retains antibiotic drugs longer than the label withhold time.
After every milking.
- Testing this frequently saves money, because you can catch mistakes early before dumping good milk on top of bad milk.
- The earlier you detect residue contamination, the less milk you’ll dump and the lower the financial impact.
Just before pickup.
This is the most critical point of all because it’s the last chance to catch contamination before the milk is shipped.
Unmatched residue detection
The IDEXX Snap tests detect more beta-lactam residues, including cephalexin, than any rapid dairy test. Test can be done on raw milk, UHT milk, sterilized milk, reconstituted milk powder, thawed milk, and skimmed milk. Species include cows, ewes, goats, mares, camels, and buffaloes.
Rugged and versatile
Test raw or comingled milk on the go, without heat. Farmers, truck drivers, and laboratories can read test results visually or by using the SNAPshot* DSR Reader without heating.
Backed by IDEXX
Process milk with confidence knowing that our rigorous quality control standards include ISO 9001 facility certification and independent validation.
