For the second time in less than 24 hours, the Canadian Food Inspection Agency has added more products to the list of foods recalled due to a salmonella contamination in Las Vegas.

A total of 18 products have now been recalled in Canada.

All products contain hydrolysed vegetable protein (HVP), a common flavour enhancer manufactured by Basic Food Flavors, Inc. The contamination caused a massive recall of approximately 50 products south of the border and a handful sold and manufactured in Canada.

On Tuesday, the CFIA added the following four products made or sold in Canada to the recall:

  • Sabatini's Gourmet Spinach Dip, 250 and 500 g (UPC 6 25616 00135 9 and 6 25616 00134 2)
  • Sabatini's Gourmet Vegetable Dip 250 and 500 g (UPC 6 25616 00139 7 and 6 25616 00138 0)
  • Mom's Pantry All Dressed Popcorn Seasoning 65 g
  • No brand on label Popcorn Seasoning 65 g

Only a day before, the CFIA added the following products:

  • Family's Best Smokey Bacon Potato Chips (UPC 7 75284 14018 5)
  • No Name Onion Recipe and Soup Mix (UPC 0 60383 65353 8)
  • No Name Cream of Leek Soup Mix (UPC 0 60383 75573 7)
  • Compliments Onion Soup Mix (UPC 0 67257 11540 6)
  • Quaker Crispy Minis Rice Cakes Savoury Tomato & Basil (UPC 0 55577 10790 4)

The CFIA warns there may be more recalls on the horizon because HVP is incorporated into a number of food products.

"So that's the work that's actively taking place right now to identify those foods," said Cathy Airth of CFIA.

No illnesses linked to the recall have been confirmed in either country and CFIA says the danger to consumers is low.

"Health Canada characterized this as low risk but we like to take a cautionary approach," said Airth.

The CFIA warns that food contaminated with salmonella may not look or smell spoiled.

Salmonella may cause serious or even deadly infections in young children, the elderly and people with weakened immune systems.

Others may experience short-term symptoms including headaches, vomiting, diarrhea and nausea.
