Listeria, Salmonella & E. coli — How HPP Eliminates the Risk

Listeria, Salmonella, and E. coli are pathogens that can cause foodborne illness with very serious consequences. Retailers are frequently required to issue recalls, and a single incident can permanently damage a brand. The Listeria bacterium alone is responsible for around 100 deaths per year in the UK and EU. Pregnant women, newborns, the elderly, and people with weakened immune systems are at greatest risk — and these groups are often the most loyal consumers of the chilled, ready-to-eat products most at risk.
Reports of recalls appear regularly in the trade press. The question for any food manufacturer is not whether the risk exists, but whether they have done everything reasonable to eliminate it.

HPP Offers the Solution
High Pressure Processing (HPP) subjects sealed, packaged food products to pressures of up to 600 MPa — equivalent to six times the deepest point of the ocean. This pressure neutralises Listeria, Salmonella, and E. coli to a 5-log reduction, meaning a 99.999% kill rate, without the use of heat, chemicals, or preservatives.
HPP has been used commercially in the United States for over 25 years and is now rapidly gaining adoption across the UK and Europe. It is not only the most effective pathogen control technology available for ready-to-eat products — it also extends shelf life by 3 to 5 times compared to conventional preservation, and eliminates the need for E-numbers, preservatives, and artificial additives.
Your Product, Your Consumer, Your Customer, and Your Reputation
HPP is particularly well suited to ready-to-eat meats, cooked and cured charcuterie, smoked fish, seafood, dips and spreads, raw vegetable products, and cold-pressed juices. If your product is consumed without further cooking, HPP is the most robust line of defence available.
A Listeria recall does not just cost money in product destruction and retailer penalties. It costs you the listing. It costs you the trust of your retail buyer. It costs you the confidence of the consumer who bought your product and became ill.
HPP is not just a food safety tool — it is a commercial risk management decision.
