Cold-pressed juice is extracted by mechanically pressing fruit and vegetables without heat. Pressing keeps the fresh flavour, but it does nothing to remove microbes carried on the produce. “Cold-pressed” is not one of the reserved juice names in the Fruit Juices and Fruit Nectars (England) Regulations 2013[8], so it describes the extraction method, not safety, and the rest of the label must not mislead about how the drink was made[9].
Two kinds of cold-pressed juice reach the shelf. Untreated (raw) juice has had no step to reduce pathogens and typically carries a short chilled life. HPP juice has been treated in the sealed bottle by high pressure processing, a non-thermal kill step. Some brands also pasteurise gently with heat. Is cold-pressed juice safe? That depends on which of these it is and on how well the controls behind it work.
Without a treatment, juice carries forward whatever came in on the raw produce from soil, water, animals and handling. The FSA notes that the low pH of fruit generally prevents pathogenic bacteria from growing, but that pathogens can survive without increasing in number, which is a particular concern in unpasteurised products[1]. Acidity is a useful hurdle, not a kill step.
Shiga toxin-producing E. coli (STEC) such as O157:H7, Salmonella and the parasite Cryptosporidium are the causes most often found in juice outbreaks, with Listeria monocytogenes a concern in chilled products. US surveillance recorded 21 juice-associated outbreaks from 1995 to 2005, with 1,366 illnesses; of the 13 with a known cause, five were Salmonella and five E. coli O157:H7[7].
The best-documented case is a 1996 outbreak linked to one brand of unpasteurised commercial apple juice in the western US and British Columbia. Seventy people were infected with E. coli O157:H7, 25 were hospitalised, 14 developed haemolytic uraemic syndrome and one died. Investigators suspected incoming apples, including lots from an orchard visited by deer, and concluded that standard procedures at a modern plant were not enough to eliminate the pathogen[6]. Outbreaks like this led the US FDA to adopt its juice HACCP rule in 2001[10].
Under 21 CFR 120.24, US juice processors must apply controls that consistently achieve at least a 5-log (99.999%) reduction in the pertinent microorganism, the most resistant pathogen of public health significance likely to occur in the juice, for at least the shelf life under normal and moderate abuse conditions[5]. Juice that has not been processed this way must carry a warning when sold to consumers: “This product has not been pasteurized and, therefore, may contain harmful bacteria that can cause serious illness in children, the elderly, and persons with weakened immune systems.”[11]
GB law has no juice-specific log-reduction rule or warning statement. Instead, food business operators must not place unsafe food on the market and must withdraw, recall and inform the authorities when food they supplied is unsafe[12]; they must run HACCP-based procedures[13]; and unpasteurised ready-to-eat juices must meet a Salmonella food safety criterion (not detected in 25 g) and an E. coli process hygiene criterion[14]. Many UK producers still use the US 5-log figure as their validation target, because it is the clearest published benchmark.
High pressure processing treats the sealed bottle at pressures typically between 400 and 600 MPa, held for 1.5 to 6 minutes. Its effect on vegetative microorganisms depends on the food’s pH and water activity, the pressure and hold time, and the organism, strain and its physiological state. HPP does not inactivate bacterial spores[2].
Pathogen strains vary widely in their resistance to pressure, and the juice’s pH and soluble solids change that resistance, so a validation study must use challenge strains and a matrix that match the real recipe[15]. A process proven on apple juice cannot simply be assumed for a low-acid green juice.
Spores matter because low-acid juices, such as carrot or many vegetable blends, have no acidity barrier. In 2006, pasteurised carrot juice caused six cases of severe botulism in Georgia, Florida and Ontario; the juice had no barrier to Clostridium botulinum other than refrigeration, and inappropriate refrigeration probably allowed toxin to form[16]. For HPP juice the lesson is the same: the bottle must stay cold from the plant to the consumer, and the date mark must come from a shelf-life study.
The recalls below are drawn from FDA enforcement data, FDA recall notices and FSA alerts. They show the four ways a cold-pressed juice usually ends up recalled: no treatment, an incomplete treatment, a labelling error and spoilage.
| Year | Product and market | What went wrong | Outcome |
|---|---|---|---|
| 2018 | Luckyberry Cold-Pressed Juice, nine variants, Lawrence, Kansas (US) | Unpasteurised juice distributed to retailers in violation of the juice HACCP rule | Voluntary recall, FDA Class II[17] |
| 2020 | Lidl Naturis Cold Pressed Juice ‘Rooting For You’ variant, 750 ml (GB) | Sulphur dioxide not correctly declared on the label | Recall with FSA allergy alert FSA-AA-26-2020[18] |
| 2024 | Happy Moose Tropical Roots and Strawberry Fields, 12 fl oz, made by co-manufacturer Youngstown Grape Distributors (US) | Part of the production run did not complete HPP; found after complaints of spoiled juice | 2,718 bottles produced; no illnesses reported; FDA Class II, with three Farmers Juice products[3][19] |
| 2025 | Everpress Juice, seven ‘JUICE from the Raw’ products, Philadelphia (US) | Under-processed product that may contain pathogenic bacteria | Initiated 24 July 2025; FDA Class I on 2 February 2026; shipped to 24 states[4] |
Spoilage recalls happen too. In 2018 PepsiCo recalled a batch of Tropicana Trop 50 Multivitamins juice in the UK because fermentation was spoiling it: bottles could appear bloated, with sediment or fizz[20]. That was an ambient juice, not a cold-pressed one, but the mechanism, organisms surviving and growing in the pack, is the same risk an HPP juice faces when hygiene, treatment or temperature control slips. FRL’s analysis of the Slimsy squash swollen-bottle recall looks at the same failure in a concentrate.
In the US, FDA classifies recalls by risk. Class I covers products with a reasonable probability of causing serious adverse health consequences or death; Class II covers products that may cause temporary or medically reversible effects, or where the probability of serious consequences is remote[21]. FDA placed the Everpress under-processing recall in Class I and the Happy Moose incomplete-HPP recall in Class II[4][19]. In both, the finding was that a treatment the product relied on had not been fully delivered, not that illness had occurred.
In the Luckyberry case, the finding was simpler: juice sold through retailers without the process controls the juice HACCP rule requires[17]. In the UK Naturis case, the issue was an undeclared allergen, which made the product a risk to people sensitive to sulphites even though nothing was wrong with its microbiology[18].
| Failure | Documented example | Control that prevents it |
|---|---|---|
| Contaminated raw produce | 1996 apple juice outbreak, apples from a deer-visited orchard and decayed fruit suspected[6] | Supplier approval, culling, washing, then a validated kill step |
| No treatment | Luckyberry, 2018[17] | HACCP plan with a kill step, or clear labelling and controls for raw juice |
| Incomplete treatment | Happy Moose, 2024; Everpress, 2025[3][4] | Pressure and hold records per batch, physical segregation of treated and untreated packs, release check before dispatch |
| Temperature abuse of a low-acid juice | Carrot juice botulism, 2006[16] | Cold chain monitoring, clear storage instructions, date set from a shelf-life study |
| Spoilage organisms | Tropicana Trop 50, UK, 2018[20] | Hygiene and CIP, preservation hurdles, shelf-life and challenge testing |
| Labelling error | Naturis, UK, 2020; 3 of 30 orange juices with sugar below the declared value in FSA sampling[18][22] | Label check against the final recipe and test results, allergen review |
For cold-pressed juice, prevention is layered and release is the last gate. The full production chain is set out in how beverages are manufactured; the controls that matter most for juice are below.
| Control | What it does | Record to keep |
|---|---|---|
| Raw material control | Limits what enters the press | Supplier approval, intake checks, test results |
| Validated treatment | HPP or heat reduces pathogens by a known, validated amount | Pressure and hold, or time and temperature, for every batch |
| Segregation | Stops untreated bottles being dispatched as treated | Batch status labels, treated/untreated counts |
| Hygiene and CIP | Prevents re-contamination after treatment | Cleaning and verification logs |
| Cold chain | Slows growth in chilled product and prevents toxin formation in low-acid juices | Storage and distribution temperatures |
| Release criteria | Stops a failing batch leaving the plant | Batch release record, micro results, shelf-life data |
Formulator’s note: treat each juice as its own validation case. Apple, citrus and green juices differ in pH and soluble solids, so confirm the pressure, hold time and cold chain on each recipe, and challenge-test where the risk justifies it.
To choose between HPP and heat, see HPP vs thermal pasteurisation and hot fill vs cold fill vs aseptic vs HPP. To set the date mark, see real-time vs accelerated shelf-life testing. FRL’s cold-pressed juice lab note records a trial comparing low-temperature, HTST and UHT heat treatments on a juice prototype. More cases are collected in our recall insights.
Is cold-pressed juice safe? It is much safer when a validated treatment, good hygiene and an unbroken cold chain sit behind it, and risky when the word “cold-pressed” is all there is. The recalls on record show that the treatment has to be delivered to every bottle, the label has to match the recipe, and the date has to come from data. Test the process, not only the product.

Cold-pressed juice is much safer when treated by HPP or gentle pasteurisation, made hygienically and kept cold. Untreated juice can carry E. coli O157, Salmonella or Listeria from the produce; US law makes untreated juice warn that the risk is greatest for children, older people and anyone with a weakened immune system.
Pressing does not kill microbes, so pathogens on the fruit or vegetables pass into the juice. Fruit acidity usually stops them growing, but the FSA notes they can survive without multiplying. A 1996 unpasteurised apple juice outbreak in North America infected 70 people with E. coli O157:H7, and one person died.
HPP greatly reduces vegetative pathogens such as E. coli, Salmonella and Listeria when the pressure and hold time have been validated for that recipe. It does not kill bacterial spores, so HPP juice must stay refrigerated, and every bottle must actually complete the cycle. Hygiene and raw material control still matter.
Most cold-pressed juice recalls come from four causes: juice sold with no kill step, a treatment such as HPP that was not completed, a labelling error such as an undeclared allergen, or spoilage that makes bottles swell. FDA and FSA records include examples of each, from Luckyberry and Happy Moose to Lidl’s Naturis juice.
There is no single answer. Untreated juice usually has a short chilled life, and HPP extends it, but the safe date depends on the recipe, pH, starting microbial load, pack and storage temperature. The date mark should come from a shelf-life study on the real product, including challenge testing where pathogens could grow.
No. GB law does not require juice to be pasteurised or set a juice-specific log reduction. Producers must still place only safe food on the market, run HACCP-based controls, and meet the microbiological criteria for unpasteurised ready-to-eat juices: Salmonella not detected in 25 g, plus an E. coli process hygiene limit.
