Expired Yogurt and Food Poisoning

Food poisoning can follow contaminated food, but an expired date alone does not prove that yogurt caused the illness. Spoilage may change smell, taste, texture, or the container’s appearance; do not taste food that seems unsafe. Symptoms can include nausea, vomiting, diarrhoea, abdominal pain, and fever. They may begin after a delay, so consider other foods and contacts as well. Young children, older adults, pregnant people, and those with weakened immunity can become dehydrated more quickly. Keep the container or product details if a clinician needs to assess a possible foodborne illness.

Stop eating the yogurt and avoid serving it to anyone else. Take frequent small sips of water or an oral rehydration solution, particularly after vomiting or diarrhoea. When appetite returns, choose foods that feel easy to tolerate and rest. Wash hands carefully and clean surfaces to reduce spread if infection is possible. Do not take leftover antibiotics or use anti-diarrhoeal medicine without checking whether it is suitable. Oral rehydration therapy can help replace water and salts; IV fluid therapy may be considered when dehydration is significant or oral fluids cannot stay down.

Seek urgent care for confusion, fainting, very little urine, severe weakness, inability to keep fluids down, blood in vomit or stool, severe abdominal pain, or breathing difficulty. Contact a clinician for persistent vomiting or diarrhoea, high or ongoing fever, or symptoms in a person at higher risk of dehydration. Get advice if several people who shared the yogurt become ill or if a food safety concern needs reporting.

Could this be food poisoning or another infection? How much oral rehydration solution should I take? Do my symptoms or health conditions make testing, treatment, or IV fluids appropriate?
