Sample of prepackaged frozen giant scarlet shrimps detected with mercury exceeding legal limit
The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department today (June 9) announced that a sample of prepackaged frozen giant scarlet shrimps imported from Spain was detected with mercury, a metallic contaminant, at a level exceeding the legal limit. The CFS is following up on the incident. Members of the public should not consume the affected batch of the product. The trade should also stop using or selling the affected batch of the product immediately if they possess it.
Product details are as follows:
Product name: Frozen Giant Scarlet Shrimp
Place of origin: Spain
Pack Lot: FCCAR25114
Best-before: April 2027
Importer: Classic Fine Foods (Hong Kong) Limited
"The CFS collected the above-mentioned sample at the import level for testing under its routine Food Surveillance Programme. The test result showed that the sample contained mercury at a level of 0.85 parts per million (ppm), exceeding the legal limit of 0.5 ppm," a spokesman for the CFS said.
The spokesman said that the CFS had informed the importer concerned of the irregularity and instructed it to stop sale and remove from shelves the affected product. The importer concerned has initiated a recall according to the CFS' instructions. Members of the public may call the importer's hotline at 2612 2066 during office hours for enquiries about the recall. The CFS is also tracing the source and distribution of the product concerned.
"Mercury may affect the nervous system, particularly the developing brain. At high levels, mercury can affect foetal brain development, and affect vision, hearing, muscle co-ordination and memory in adults," the spokesman added.
According to the Food Adulteration (Metallic Contamination) Regulations (Cap. 132V), any person who sells food with metallic contamination above the legal limit is liable upon conviction to a fine of $50,000 and imprisonment for six months.
The CFS will alert the Spanish authorities and the trade, continue to follow up on the incident and take appropriate action. An investigation is ongoing.
FEHD releases fourth batch of gravidtrap indexes for Aedes albopictus in May

The fourth batch of gravidtrap indexes for Aedes albopictus in May includes First Phase Gravidtrap Indexes covering six survey areas and Area Gravidtrap Indexes covering six survey areas. Among which, six survey areas recorded gravidtrap indexes above 10 per cent, while Aberdeen and Ap Lei Chau in Southern District recorded a gravidtrap index above 20 per cent. Meanwhile, the gravidtrap indexes of six survey areas, namely Kennedy Town and Shek Tong Tsui in Central and Western District; North Point and Quarry Bay in Eastern District; Shau Kei Wan and Sai Wan Ho in Eastern District; Aberdeen and Ap Lei Chau in Southern District; Tai Po East in Tai Po District; and Tuen Mun South in Tuen Mun District, have recorded a decrease as compared to the indexes recorded in the last survey period, reflecting the progress of relevant mosquito control work.
With reference to the data from the past few years, the gravidtrap indexes start to rise from April or May every year. The actual timing and extent of the rise are affected by factors like weather conditions and rainfall. The average temperature and rainfall recorded in April this year were higher than those in the same period last year, creating favourable conditions for mosquito growth and breeding. As a result, the rise in gravidtrap indexes occurred earlier this year. With the increase in rainfall in May, the gravidtrap indexes are expected to rise further.
For survey areas which recorded indexes exceeding 10 per cent, in accordance with the mechanism implemented by the FEHD in response to the chikungunya fever (CF) situation (i.e. strengthening mosquito control work in areas with a gravidtrap index between 10 per cent and 20 per cent, instead of 20 per cent or above under the original mechanism), the FEHD is collaborating with relevant departments and stakeholders to identify locations with high mosquito infestations and carry out intensive and targeted mosquito control measures. The FEHD has initiated two prosecutions against the relevant construction site contractors following the discovery of mosquito breeding at construction sites in Tai Po District and Southern District. Moreover, following the discovery of stagnant water or stagnant water containers in a park, a construction site, a private housing estate, a clinic and a private premises in Tai Po District, Central and Western District, as well as Southern District, the FEHD has issued five statutory notices to the responsible persons-in-charge, requiring the clearance of such items within a specified timeframe. The FEHD, the relevant departments and stakeholders are following up on the mosquito control work, and will also organise exhibitions, distribute leaflets and posters, and notify residential estates that have subscribed to the gravidtrap Rapid Alert System, advising property management agents and residents to stay vigilant and work together in taking mosquito prevention and elimination measures. In addition, the FEHD will strengthen the monitoring of the gravidtrap index in the areas to review the effectiveness of the mosquito control work.
Public participation is crucial to the effective control of mosquito problems. The FEHD appeals to members of the public to continue to work together in strengthening personal mosquito control measures, including:
tidy up their premises and check for any accumulation of water inside the premises;
remove all unnecessary water collections and eliminate the sources;
check household items (those placed in outdoor and open areas in particular), such as refuse containers, vases, air conditioner drip trays, and laundry racks to prevent stagnant water;
change water in flower vases and scrub their inner surfaces thoroughly, and remove water in saucers under potted plants at least once a week;
properly cover all containers that hold water to prevent mosquitoes from accessing the water;
properly dispose of articles that can contain water, such as disposable meal boxes and empty cans; and
scrub drains and surface sewers with alkaline detergent at least once a week to remove any mosquito eggs.
Starting in August 2025, following the completion of the surveillance of individual survey areas, and once the latest gravidtrap index and the density index are available, the FEHD has been disseminating relevant information through press releases, its website and social media. It aims to allow members of the public to quickly grasp the mosquito infestation situation and strengthen mosquito control efforts, thereby reducing the risk of CF transmission.
Following recommendations from the World Health Organization and taking into account the local situation in Hong Kong, the FEHD sets up gravidtraps in districts where mosquito-borne diseases have been recorded in the past, as well as in densely populated places such as housing estates, hospitals and schools to monitor the breeding and distribution of Aedes albopictus mosquitoes, which can transmit CF and dengue fever. At present, the FEHD has set up gravidtraps in 62 survey areas of the community, with a surveillance period of two weeks. During the surveillance period, the FEHD will collect the gravidtraps once a week. After the first week of surveillance, the FEHD will immediately examine the glue boards inside the retrieved gravidtraps for the presence of adult Aedine mosquitoes to compile the Gravidtrap Index (First Phase) and Density Index (First Phase). At the end of the second week of surveillance, the FEHD will instantly check the glue boards for the presence of adult Aedine mosquitoes. Data from the two weeks of surveillance will be combined to obtain the Area Gravidtrap Index and the Area Density Index. The gravidtrap and density indexes for Aedes albopictus in different survey areas, as well as information on mosquito prevention and control measures, are available on the department's webpage (www.fehd.gov.hk/english/pestcontrol/dengue_fever/Dengue_Fever_Gravidtrap_Index_Update.html#).
