This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Telling Porkies?
'Porkies' is derived from Cockney rhyming slang. Porkie pies/lies. 10% of sampled pork products in UK supermarkets have recently be shown to contain a dangerous antibiotic-resistant bacterium (https://www.theguardian.com/world/2022/jul/05/potentially-deadly-superbug-found-in-british-supermarket-pork). This bacterium is a variant of entercoccus, resistant to vancomycin (an anti-biotic of 'last resort' in human treatments). This bacterium can cause urinary tract/wound infections. In extreme cases, this 'superbug' can infect the bloodstream, the heart and/or the brain. The antibiotic-resistant bacterium was found in joints, chops and mince that mainly originated from british farms. Worryingly, it was found in some products that had been assured by the 'Red Tractor' or the 'RSPCA' (Royal Society for the Prevention of Cruelty to Animals) schemes. Some pork sold as 'organic', also contained the 'superbug'. Many of these designations specify 'responsible' use of antibiotics in pig stocks. Antibiotics (like vancomycin) are allowed for treatment of pig infections. These medications are not supposed to be used, however, as growth enhancers. Antibiotics are used to boost profits in many other parts of the world. 'Superbugs' are developed by over-use of antibiotics. The process essentially selects those bacterial variants that can survive exposure to the particular antibiotic. A limited number of antibiotics are available. Superbugs kill around 700,000 people each year.
