Science Diet Dog Food Recall History

When considering any commercial dog food brand, it’s important to review their recall history. Recalls indicate issues with food safety and quality control.

Science Diet has been recalled three times in recent history:

  • Feb 2022: Select canned dog food recalled due to potentially elevated levels of Vitamin D.
  • March 2019: Multiple canned dog foods recalled for excessive Vitamin D.
  • Sept 2010: Dry cat and ferret foods recalled for potential Salmonella contamination.

The February 2022 and March 2019 recalls both involved excessive and potentially toxic levels of Vitamin D due to supplier manufacturing errors. Excess Vitamin D can cause vomiting, lethargy, loss of appetite, increased thirst and urination, muscle tremors and seizures.

No dog food was affected in the 2010 Salmonella recall.

Overall, Science Diet has a relatively low rate of recalls compared to many other brands, signaling good quality control practices. The Vitamin D recalls involved their canned foods, not kibble.
