Sushi could secretly be spreading antibiotic resistance
Antibiotic-resistant bacteria are an increasing area of concern for health experts and scientists are concerned that the popular food sushi could be spreading it. Researchers at the Norwegian University of Science and Technology were interested in looking at the health implications of sushi, which is considered pretty standard fare in the country. Dr. Hyejeong Lee, who recently completed her PhD at the Department of Biotechnology and Food Science at NTNU, investigated different varieties of Aeromonas bacteria in seafood products that aren’t processed in a way that reduces bacteria, such as sashimi (raw fish) and cold-smoked fish. Lee explained: “The goal was to gain more knowledge about Aeromonas in this type of seafood – both the bacteria’s role in the deterioration of the product and in causing disease. Furthermore, we wanted to see if raw seafood can spread antibiotic-resistant bacteria.” While Listeria monocytogenes is the most well-known bacteria that can cause illness from unprocessed seafood, the prevalence of Aeromonas in similar products is an increasing worry for scientists for another reason. This is because Aeromonas bacteria frequently exchange genetic material with other bacteria in the sea, which means they can inherit and spread resistance to antibiotics before ending up in sushi. Lee explained: “Some strains of Aeromonas can also spread antibiotic resistance from one type of bacteria to another. Eating seafood infected by resistant bacteria is a likely way these bacteria can spread from marine animals and environments to humans.” Resistant bacteria are foreseen to be a big problem in the future, with the worst-case scenario being that few or no antibiotics will work at treating them. Experts believe it is important that antibiotic resistance is seen as a broad approach that is seriously considered in all aspects of society. Anita Nordeng Jakobsen, associate professor at NTNU’s Department of Biotechnology and Food Science, explained: “To combat the spread of antibiotic-resistant bacteria, it is important that we adopt a broad approach that looks at animal and human health, food production and the environment together in order to achieve better public health.” Still, Lee was quick to emphasise that the risk of getting sick from Aeromonas is very small, especially for healthy people. But, she stressed: “Aeromonas is often ignored when we talk about food safety. I think my research highlights that the food industry needs to pay more attention to these bacteria."

A new Titanic expedition is being planned – and the US government wants to stop it
You would think people would read the room, and learn from the tragic and fatal implosion of the Oceangate submersible in July, yet there’s already plans for another trip down to the Titanic wreckage next year – and the US government doesn’t want it to go ahead. Two months after the Titan sub crushed underwater, killing five people, officials are trying to stop Georgia-based firm RMS Titanic Inc. (RMST) from trying to recover further historical items from the wreckage to add to its collection of artifacts it exhibits. While RMST owns the salvage rights to the doomed liner which infamously struck an iceberg and sank in 1912, the US government is drawing attention to both federal law and an international agreement which classes the shipwreck as a hallowed gravesite. According to the Associated Press, the government states in court documents filed on Friday that RMST is “not free to disregard” the “validly enacted federal law” mentioned above, but it nonetheless is “its stated intent”. “[The shipwreck] will be deprived of the protections Congress granted it,” its lawyers argue. RMST, meanwhile, says it looks to take images of the entire site, including areas where “deterioration has opened chasms sufficient to permit a remotely operated vehicle to penetrate the hull without interfering with the current structure”. Provided the objects are not “affixed to the wreck itself”, artefacts recovered could include items from “inside the Marconi room” – that’s the room where the ship’s wireless radio was used to communicate with other vessels and those on the shore. RMST also insists they do not plan to cut into or detach any part of the wreck “at this time”, but that they don’t plan to seek a permit from the National Oceanic and Atmospheric Administration (NOAA) – something the US government says it needs in order for the firm to move forward with its plans. The NOAA oversees the public interest in the Titanic, and on its website accepts it “may be in the public’s interest to salvage some artifacts” from the wreckage. “NOAA therefore balances this value with the Congressional intent to manage the wreck site as a maritime memorial consistent with the International Agreement, which proclaims that the Titanic shall be recognized as a memorial to those who perished. “NOAA has concluded that the recovery of many of the artifacts from the debris field (with certain exceptions) is consistent with the NOAA Guidelines and the International Agreement, including the in situ preservation policy. “However, NOAA has also determined that recovery of artifacts from within either of the two hull sections is not consistent with the purposes of a maritime memorial.” It’s not the first time the US government and RMST have had a legal battle over the ship, as back in 2020 a similar case concerning a planned expedition made its way to the courts, before the coronavirus pandemic scuppered proposals and the issue didn’t go any further.
