Can spoiled juice make you sick?
Drinking juice is a tasty way to get vitamins and nutrients. But what happens if you accidentally drink juice that’s past its expiration date or has been sitting out too long? Can spoiled juice make you sick?
How Juice Spoils
Freshly squeezed juice can start to spoil soon after it’s made. Bacteria, mold, and yeast begin multiplying quickly in the sugary, wet environment. Enzymes in the juice also start breaking down vitamins, phytochemicals, and antioxidants. Here are the main ways juice can spoil:
- Fermentation – Yeasts convert natural sugars into alcohol and carbon dioxide, causing carbonation and alcohol taste.
- Mold growth – Mold spores floating in the air land on the juice and grow fuzz or cotton-like colonies.
- Bacterial spoilage – Bacteria produce gas, acid, rotting, or slimy textures.
- Oxidation – Exposure to air causes vitamin loss and color/flavor changes.
- Enzyme action – Natural enzymes degrade nutrients, proteins, fats, and vitamins.
Pasteurization and refrigeration help slow these spoilage processes. But no juice stays fresh forever, especially once opened.
Signs Juice Has Spoiled
Watch for these clues that your juice is past its prime:
- Appearance – Cloudiness, particles, foam, slime, or color changes
- Texture – Thick, sticky, ropy, or slimy consistency
- Smell – Fermented, rotten, sour, or moldy odors
- Taste – Alcoholic, sharp, bitter, sour, or “off” flavors
- Gas – Bubbles, fizzing, or hissing sounds
- Mold – Cottony, dry fuzz or spots on surface
The more signs of spoilage, the more risky it is to drink. Trust your senses – if juice doesn’t look, smell or taste normal, play it safe and toss it out.
Dangers of Drinking Spoiled Juice
So what actually happens if you drink spoiled juice? Here are some potential health effects:
- Food poisoning – Bacteria like salmonella, listeria, and E. coli can grow in juice, causing vomiting, diarrhea, fever, and cramps.
- Toxic mold – Mold can produce mycotoxins that cause allergic reactions or liver damage.
- Food intolerances – Fermented juice contains higher histamine levels, irritating those with intolerances.
- Alcohol toxicity – Enough fermented juice can cause intoxication, especially in children.
- Loss of nutrition – Spoiled juice has fewer vitamins, minerals, and antioxidants.
- Other issues – Headaches, upset stomach, or bad taste reactions are possible.
Not all spoiled juice makes you sick. Small amounts may cause no issues. But bacteria and toxins can build up to dangerous levels, so it’s better to play it safe and avoid drinking or tasting questionable juice.
Groups at Higher Risk
Some people are more likely to become ill from contaminated juice. Higher risk groups include:
- Children
- Elderly
- Pregnant women
- Those with weak immune systems
- People with chronic diseases
Their bodies have a harder time fighting off foodborne pathogens. Babies under 12 months old should not be given juice at all due to botulism risks.
Juice Types and Spoilage Risk
Not all juices pose the same safety concerns. Here is how common juice varieties rank for spoilage risk:
Juice Type | Spoilage Risk Level |
---|---|
Unpasteurized juice | High risk |
Fresh-squeezed juice | High risk |
Cold-pressed juice | High risk |
Pasteurized juice | Moderate risk |
Shelf-stable juice | Low risk |
Vegetable juice | Low risk |
Dried juice powders | Very low risk |
Unpasteurized, fresh-squeezed, and cold-pressed juices are most prone to harbor bacteria since they are not heat treated. Acidic juices like orange or pineapple resist spoilage better than vegetable or neutral juices. And concentrated juices or juice powders have very little spoilage risk due to their low moisture content.
How Long Does Juice Last?
Under proper storage, packaged juices can stay fresh for 1-2 weeks past the “best by” date. But juices have a short shelf life once opened. Here are some juice storage guidelines:
- Unopened pasteurized juice – 2-3 weeks in fridge
- Opened pasteurized juice – 3-5 days in fridge
- Fresh squeezed juice – 1-2 days in fridge
- Juice at room temperature – 4-6 hours max
