Canada's food watchdog has issued two separate alerts, warning consumers that certain sesame seed crackers and dips have been found to be contaminated.

Sesame seed crackers distributed in Gatineau, Que., and Ottawa are being recalled because they may be tainted with salmonella bacteria, the Canadian Food Inspection Agency said Tuesday.

The recall applies to:

• Craquelins dorés, Raw Golden Chips.
  
• Crâque Pôt, Raw Gourmet Chips.
  
• Dulse Vita, Sea Magic.
  
• Les Biscrus des Gamins, Raw Cookies.
  

The crackers were sold up to and including Jan. 30.

Consumption of food contaminated with salmonella may cause serious and even deadly infections in children, the elderly and people with weakened immune systems. In healthy adults, the salmonella bacteria can cause high fevers, severe headaches, vomiting, nausea, abdominal pain and diarrhea.

The CFIA also says certain lots of Olivier brand Parmesan & Asiago Dip with Garlic & Basil have been found to be tainted with Clostridium botulinum. The recall applies to 335-gram jars with the lot codes:

• OPA 34171.
  
• OPA 23471.
  
• OAP 17271.
  
• OAP 17671.
  
• OAP 36061.
  
• OAP 36161.
  
• OPA 33961.
  

The dip was sold through Williams-Sonoma stores in Ontario, Alberta and British Columbia. The watchdog notes the product may have been sold in other stores across the country.

No illnesses associated with the crackers and the dip have been reported.

Food contaminated with Clostridium botulinum may not look or smell spoiled. Consumption of food contaminated with the toxin may cause nausea, vomiting, fatigue, dizziness, headache, double vision, dry throat, respiratory failure and paralysis. In severe cases of illness, people may die.
