Conch alert after cases of suspected poisoning in Bahamas

Khrisna Russell of Tribune 242 reports food safety officials are cautioning against the consumption of fresh conch after several suspected cases of conch poisoning.

Several reports of conch poisoning made the rounds on social media over the past few days before the Bahamas Agricultural Health and Food Safety Authority issued a statement yesterday.

The authority warned consumers to avoid fresh conch until officials are able to determine the source of the contamination.

Conch poisoning is typically caused by the bacterium, Vibrio parahaemolyticus, with contamination attributed to poor hygienic practices during its handling and preparation.

Health Minister Renward Wells said there had been about 10 reported cases of conch poisoning.

Vendors should also avoid having the conch sit in the sun for long periods of time and after the conch meat is removed, it should be gutted and rinsed thoroughly under potable running water for enough time to carefully remove all the slime and debris present. Also, vendors should wash their hands before and after preparation with liquid hand soap and warm running water for 20-30 seconds.

Gloves should also be worn when preparing conch salad or other fresh preparations where further cooking is not done.

Hair nets and disposable aprons should also be worn to prevent cross contamination. Gloves should be changed regularly if they become torn or in between tasks.

Other precautions include conch salad vendors utilising separate cutting boards for slicing vegetables and the conch. Cutting boards and utensils should be cleaned and sanitised in between preparations to avoid cross contamination or the carryover of contamination between preparations.

Consumers are urged to be vigilant to ensure that wherever they are purchasing raw conch dishes, vendors are following hygienic practices. Those who purchase raw conch to prepare at home should follow these preparation steps as well.

Food safety and tourism are mutually dependent: Vibrio in conch in Bahamas

Morgan Adderley of Tribune 242 reports there have been four confirmed cases of conch poisoning and as many as six unconfirmed cases, Bahamas Health Minister Duane Sands announced yesterday.

According to Dr Sands, the exposure took place in the previous 72 to 96 hours with a number of the patients affected having eaten at Potter’s Cay.

Noting that an outbreak of conch poisoning is something the country can “ill afford” right now, Dr Sands was adamant the issue can be easily mitigated if proper hygiene is maintained.

Four cases have been confirmed via laboratory testing but Dr Sands said there are a number of unconfirmed cases – “possibly as many as six” awaiting laboratory results. He added the affected people are being treated at both Doctors Hospital and Princess Margaret Hospital, and so far, all the self-identified patients are Bahamian.

Dr Sands said the steps to controlling the outbreak lie in proper hygiene and public and vendor awareness.

“Environmental Health teams (are speaking) directly with the vendors, not only at Potter’s Cay but throughout New Providence and anywhere else that we may have reason to suspect possibility of exposure,” Dr Sands said.

“We learned back in the 1990s that this is easily controlled if people practice very simple techniques of washing conch with fresh water. And that minimises, if not eliminates the possibility of transmission.

If it’s so simple, why do so many people get sick?
