Consumer Reports recently tested 300+ frozen produce samples, focusing on their safety and nutritional value. Here's what you need to know:
Test Results
- No harmful bacteria like E. coli, listeria, or salmonella were detected in tested samples.
- Brands tested include popular names like Trader Joe's, Birds Eye, Great Value, and Dole.
Listeria Concerns
- Listeria monocytogenes is a key risk because it thrives in cold environments. While freezing halts bacteria growth, it doesn’t kill listeria.
- Listeria contamination is rare but dangerous, especially for pregnant people, older adults, and those with compromised immune systems.
Recalled Items
- Between 2017 and 2021, frozen fruits and vegetables were frequently recalled for listeria, norovirus, and hepatitis A.
Cooking is Crucial
- Cooking frozen vegetables minimizes risks for high-risk individuals. Frozen fruits, often eaten raw in smoothies, are more likely to harbor pathogens like hepatitis A or norovirus.
Nutritional Value
- Frozen produce retains most nutrients since it’s frozen soon after harvest.
- In some cases, frozen fruits and vegetables have higher vitamin levels than fresh produce stored for days.
Research Highlights
- A 2015 study found higher levels of some vitamins in frozen produce.
- A 2017 study revealed frozen items often outperform fresh produce stored for five days.
Practical Benefits
- Frozen produce lasts longer, reducing food waste.
- Easier prep (no chopping or washing).
For High-Risk Individuals
- Always cook frozen vegetables, especially if pregnant, immunocompromised, or serving children.
Handling Frozen Fruits
- Consider briefly cooking berries or other fruits before use in high-risk settings.
Variety is Key
- Combine fresh and frozen produce to maximize nutrition and variety.
Frozen fruits and vegetables are generally safe and nutritionally comparable to fresh produce. They’re convenient, budget-friendly, and can help reduce food waste. However, take precautions when serving raw frozen produce, especially for high-risk groups.
