229 people were sick and 45 needed hospital treatment after eating sandwiches, produced by an unlicensed food factory in Hong Kong and contaminated with salmonella.

The Centre for Health Protection (CHP) of the Department of Health found 96 clusters of suspected food poisoning related to the suspected sandwiches. All those affected are now in stable condition.

Retail outlets have been instructed to stop sale of the concerned products and the manufacturer to stop production. (we were not able to find further details of the suspected products)

The majority of outbreaks of salmonellosis in sandwiches, are related to eggs.

Infection with salmonella in developed countries generally results in food poisoning. The organisms enter through the digestive tract and must be ingested in large numbers to cause disease in healthy adults. Between 60% to 80% of salmonella infections cases go un-diagnosed.

Risk factors for salmonella infections include a variety of foods. Meats such as chicken and pork have the possibility to be contaminated. A variety of vegetables and sprouts may also have salmonella. Lastly, a variety of processed foods such as chicken nuggets and pot pies may also contain this bacteria.

Salmonella was first visualized in 1880. The name Salmonella was not used until 1900.
