Make sure to check the box before whipping up some cake batter.
On Monday, General Mills Canada recalled Betty Crocker Super Moist brand Cake Mix Rainbow Bit over possible E. coli contamination.
The Canadian Food Inspection Agency is conducting a food safety investigation, which may lead to the recall of other products.
In a Health Canada advisory, people are warned not to consume the recalled product, which could cause sickness.
So far, there have been no reported illnesses linked to the consumption of the cake mix in Canada.
People are told to check if they have the recalled product at home; these should be thrown out or returned to the purchase store.
Health Canada said food contaminated with E. coli might not look or smell spoiled, but can still make consumers sick.
Symptoms include nausea, vomiting, mild to severe abdominal cramps and watery to bloody diarrhea.
More serious cases could lead to some people having seizures or strokes, needing blood transfusions and kidney dialysis or living with permanent kidney damage.
In severe cases of illness, people may die.
