The advice comes from the Ministry of Health (MOH) and the Agri-Food and Veterinary Authority (AVA). The two agencies say these cakes are likely to contain a bacteria called Salmonella Enteriditis, which has caused some people to get food poisoning. Salmonella is a group of bacteria that can cause symptoms such as fever, watery diarrhoea, vomiting and abdominal pain. 106 people have so far reported getting food poisoning after eating the cakes. Six had to be hospitalised, but have since been discharged. They tested positive for Salmonella Enteritidis. Quality Management Slide 29 of 35 6. 1 Cost of Poor Quality
