Whole cooked ham is a staple in many diets, but the nitrite used to preserve it raises health worries. A new study looked at how cutting nitrite from 150 ppm to 80 ppm affects safety, texture, and flavor over time.  

The researchers checked the meat every 15 days for bacteria like total viable counts, lactic acid bacteria, and harmful species such as Staphylococcus aureus and Escherichia coli. All counts stayed well below dangerous levels, and no Salmonella or Listeria were found in any sample.  

They also challenged the ham with dangerous bacteria, simulating storage up to 35 days and even a temperature slip to 8 °C. The lower‑nitrite ham still stopped Clostridium spores from growing and slowed Listeria, showing it remains protective.  

When they measured color, moisture retention, and texture, the low‑nitrite ham matched the regular version exactly—no noticeable difference in look or feel.  

The study monitored pH, water activity, and remaining nitrite over 90 days. The values stayed stable, with pH between 6. 0 and 6. 2, water activity close to 0. 95, and residual nitrite dropping from about 4 mg/kg to just 1 mg/kg.  

Overall, the data suggest that reducing nitrite to 80 ppm does not compromise safety or taste. The ham keeps its good texture, aroma, and flavor while meeting stricter health guidelines.
