Class II U.S. Food and Drug Administration

Siemens Healthcare Diagnostics, Inc. Immulite 2000 Oak Mix Specific Allergen recall: The barcode orientation on affected devices causes incorrect scanning order

Recall published 11 months ago

The barcode orientation on affected devices causes incorrect scanning order of tubes within the allergen holder wedge. When using an IMMULITE 2000 / IMMULITE 2000 XPi instrument in combination with a Zebra barcode scanner, the instrument will not correctly recognize the position of tubes within the allergen holder wedge.

The hazard: Undeclared allergen or ingredient

The food itself is fine. What is wrong is the label, and for the households that rely on that label it is a real risk.

What the notice says: The barcode orientation on affected devices causes incorrect scanning order of tubes within the allergen holder wedge. When using an IMMULITE 2000 / IMMULITE 2000 XPi instrument in combination with a Zebra barcode scanner, the instrument will not correctly recognize the position of tubes within the allergen holder wedge.

Why it matters: An ingredient that U.S. law requires to be declared is present but missing from the label. People who avoid that ingredient cannot make a safe choice from the packaging.

Symptoms and when to call a doctor

An undeclared allergen is a danger only to people allergic or intolerant to that ingredient. For everyone else the food is safe. Reactions range from an itchy mouth, hives, stomach cramps or vomiting through to anaphylaxis — swelling of the lips, tongue or throat, a tight chest, wheezing, a sudden drop in blood pressure or collapse. If anaphylaxis is suspected, use an epinephrine auto-injector straight away and call 911, even if the symptoms seem to settle, because a second wave can follow hours later.

What to do about Allergen

Siemens Healthcare Diagnostics, Inc. — The food itself is fine. What is wrong is the label, and for the households that rely on that label it is a real risk.

  1. Read the official notice above for the exact ingredient involved, then check whether anyone in your home avoids it.
  2. Warn anyone else who eats from your kitchen, including schools and childminders.
  3. Report any reaction to the FDA so it is recorded against this recall.
  4. If nobody here avoids it, the product is safe to eat; the refund is still available if you would rather return it.

Getting a refund without the pack

The commonest reason people skip the refund is that they have already thrown the item away. That rarely matters.

  • A photo of the label and lot code is accepted by most grocers, and so is a card statement line showing the purchase.
  • Store credit is often offered first. You can ask for the original payment method instead, and it is normally granted.
  • No photo either? Ask anyway. Grocery chains settle recall refunds at the service desk because disputing them costs more than paying them.
  • For a multi-pack or a case, ask for the full purchase price rather than a per-unit figure — the recall covers what you paid.
