We tested the spoilage of opened commercially jarred gherkin pickles after storing them in the pantry at around 70°F (21°C) for seven days. During this period, we closely monitored the pickles for any signs of spoilage. We noted a distinct change in smell, with some jars developing an off odor, while others retained their typical vinegar scent. We observed the appearance for any mold growth and noted that a few pickles had developed a slimy texture. To further verify safety, we heated a sample to 165°F (74°C) but ultimately decided to discard all questionable jars, prioritizing food safety above all.
