Health Canada has issued an advisory to parents not to give unpasteurized apple juice or other unpasteurized products including cider, fruit juices and raw milk to their children. Even the elderly and people with weak immune systems are advised not to consume such products.

The reason is that such products contain Salmonella and E. coli, which are harmful bacteria and can prove fatal. But Health Canada also said that a majority of juice in the country was safe and pasteurized. “Unpasteurized juice products can be found at some farmer’s markets, orchards, and grocery stores,” it added.

Some of the symptoms of taking unpasteurized products include stomach cramps, vomiting, fever and bloody diarrhea.
