Neogen Vet Hycoat® Hyaluronate Sodium Sterile Solution recall: Microbial Contamination

Recall published 9 months ago

Microbial Contamination

The hazard: Microbial contamination

This recall is a contamination finding. The product may be perfectly normal to look at, because testing — not appearance — is what caught it.

What the notice says: Microbial Contamination

Why it matters: The product was found, or is suspected, to carry a harmful micro-organism. The agency notice names the specific organism and that detail matters, because the illness it causes and the people most at risk differ from one to the next.

Symptoms and when to call a doctor

Most foodborne infections cause stomach cramps, diarrhoea, nausea and sometimes fever, starting anywhere from hours to weeks after exposure depending on the organism. See a doctor for a high fever, bloody diarrhoea, vomiting that stops you keeping liquids down, diarrhoea lasting more than three days, or signs of dehydration. Infants, pregnant people, adults over 65 and anyone immunocompromised should seek advice earlier.

This page is general information, not medical advice. If you feel unwell, a clinician who can see you is the only person able to judge your case.

Vet HYCOAT® Hyaluronate Sodium Sterile Solution

What the company announced

LANSING, Mich. – (BUSINESS WIRE) – Neogen Corporation (NASDAQ: NEOG) is voluntarily recalling all lots within expiry of Neogen®Vet HYCOAT® Hyaluronate Sodium Sterile Solution, for use in dogs, cats, and horses, to the veterinarian level. Neogen distributes this product, which is manufactured by a third-party supplier. This recall has been initiated due to microbial contamination in certain lots of 10 mL/50 mg product vials. Neogen received a number of reports of adverse events in horses following intraarticular injections of this product, which is inconsistent with its labeled, intended use. To date, Neogen has not received reports of adverse events when used in a manner consistent with the labeled use.

While the company’s investigation into this issue is ongoing, out of an abundance of caution the 2mL/20mg product vials are also being recalled. The company is proactively working with the FDA on this matter.

Risk Statement: This product is labeled as a sterile solution, but due to microbial contamination of certain lots, the recalled lots should no longer be considered sterile. Vials that contain a microbial contaminant potentially result in infection in the animal. The risk is particularly acute when used as an intraarticular injection (which is inconsistent with its labeled, intended use). There also is risk if used according to the label as a topical wound management system in surgical wounds, burns, ulcers, and autograft procedures. To date, Neogen has not received reports of adverse events when used in a manner consistent with the labeled use.

The product is intended for use as a topical wound management system and is packaged in vials of 2mL/20 mg (UPC Code 726087089386) and 10mL/50mg (UPC Code 726087089393).

The subject product lots within expiry include the following:

2 mL/20 mg lot numbers: 0236735, 0236736, 0336746, 0336747, 0536760, 0536761, 0636768, 0636769, 0836792, 0836785, 0836788, 0836789, 0936794, 0936795, 1036801, 1036802, 1036803, 1036804, 1136807, 1136808, 0246837, 0246838, 4L001B, 4L002

What to do about Contamination

Neogen — This recall is a contamination finding. The product may be perfectly normal to look at, because testing — not appearance — is what caught it.

  1. Stop eating it and keep it separate from other food.
  2. Bag and bin it, or return it to the store for a refund.
  3. Clean and sanitise the fridge shelf, container or surface it was stored on.
  4. Read the official notice for the organism named — the advice for Listeria, Salmonella and hepatitis A is not the same.

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.
