Can you get sick from homemade pickles?
Keeping this in view, can you get botulism from pickles?
Growth of bacteria, yeasts and/or molds can cause the film. Molds growing in pickles can use the acid as food thereby raising the pH. Making sure enough vinegar is added to the cucumbers is important to make safe pickles; Clostridium botulinum can grow in improperly canned, pickled foods with a pH higher than 4.6.
Furthermore, how can you tell if pickles are bad?
Check the pickles for signs of off-odors and mushiness of the pickles. If these signs are absent, the pickles are safe to eat. Sometimes the fillers (anticaking agents) in regular table salt may cause slight cloudiness, so always use pickling salt. Hard water might also cause cloudiness.
Fortunately for humans, C. botulinum needs a near-oxygen-free environment to grow, and doesn't like acid. Air and acids such as vinegar, lemon and lime juice help to keep us safe from food-borne botulism. That's one reason people preserve foods by pickling them in vinegar.
