SNAP Beta-Lactam ST Plus

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 Beta-Lactam ST Plus test from IDEXX


When to test for contamination by antibiotic residues

Keeping antibiotics out of the dairy supply is essential to ensure product safety, protect against bacterial 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.


On the farm, on the truck, in the dairy...

The robustness and reliability of the IDEXX SNAP Antibiotic Test makes it an ideal solution for antibiotic testing on farms. The IDEXX SNAP Beta-Lactam ST test detects beta-lactam residues in raw, mixed cows milk in just 6 minutes, without heating or incubating, You can test milk samples directly from the truck, bulk tank, or refrigerator.


Unmatched residue detection

Detects more tetracycline and 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.
