This study investigated the impact of waterfowl on the bacteriological quality of village ponds in East Yorkshire, north-east England. Water and sediment samples were collected from ponds with and without resident ducks and geese; faecal indicator and potentially pathogenic bacteria were assayed by membrane filtration and by selective enrichment. Escherichia coli, faecal streptococci and, to a degree, Clostridium perfringens were more abundant in ponds with waterfowl; Salmonella was isolated in June–August from the sediment of a pond with waterfowl. The results suggested that the bacteriological quality of village ponds might be adversely affected by waterfowl. All water samples from ponds with waterfowl had faecal indicators at higher concentrations than EU requirements for bathing waters. Although these ponds are not bathing waters we suggest skin contact and accidental ingestion of water should be avoided.

Because damaged cells may account for a substantial proportion of the bacterial population in processed foods, the food microbiologist must choose the most appropriate methods for detecting damaged as well as noninjured cells. Any method intended to recover damaged organisms should include a resuscitative, or repair, process that will restore the injured cells to a sound physiological condition before subjecting them to the severity of selective enrichment media. It should also provide a reliable indication of the microbiological safety and quality of any particular food. This paper reviews various factors that affect the recovery of Salmonella spp., which include: (a) sample rehydration, (b) period of preenrichment, (c) incubation in both aerobic and anaerobic environments, (d) media composition and (e) the relative merits of preenrichment and direct selective enrichment. Because resuscitation of injured Salmonella cells does not occur during the selective enrichment step and beyond, the effect and interaction of these factors are considered primarily for the preenrichment step of the isolation procedure for Salmonella. This paper also reviews five methods recently developed for recovery of coliforms, which include: (a) hydrophobic grid membrane filtration, (b) radiometry, (c) electrical impedance, (d) fluorogenic assay and (e) the Petrifilm system. Each of these methods may incorporate a step for resuscitation of injured organisms.

Texas Tech Pediatrics at Northwest Texas Hospital System in Amarillo, Texas, currently practices giving “Mom/Dad of the Day” cards to all new parents, offering the opportunity for fathers to auscultate the newborn heart sound, and encouraging maternal and paternal skin-to-skin contact. New parents were asked to fill out 2 anonymous surveys regarding these practices. Survey results showed statistically significant positive responses by the parents for subjective improvement in fetal sleep and feeding as well as parental confidence and preparedness for taking care of their newborn. Additionally, these practices are desired by parents, with 96% fathers recommending that the hospital routinely offering opportunities for heart auscultation and 94% parents recommending “Mom/Dad of the Day” cards for all future parents in the hospital. Small, nonmedical initiatives such as these are well received and can be feasibly adopted in more hospitals to improve patient quality of care.

Milk and milk powders are very rich in several nutrients and relished by everybody throughout the world. The present study was undertaken with the aim of investigating the bacteriological quality of locally available dry powder milk in Bangladesh. A total number of eight powder milk samples were collected from Gazipur city and its surrounding areas during the period from January 2017 to February 2017. The analysis comprised of enumeration of total viable bacterial count (TVBC), isolation of bacterial isolates and identification of pathogenic bacteria. Almost all the powder milk samples showed the total aerobic heterotrophic bacterial (TAHB) level above the standard acceptable range (>104 CFU/g). Both gram positive and gram negative pathogenic bacteria viz. Staphylococcus aureus, Staphylococcus epidermidis, Bacillus, pseudomonas sp. and Enterobacter sp. were isolated from studied samples through morphological and biochemical characteristics. Pseudomonas sp. were confirmed by API 20E. These results highlighted the necessity to maintain appropriate sanitary and hygienic measures at each critical point in order to safeguard consumers from food borne pathogens.Asian J. Med. Biol.

The Impact

The main sources of potential ‘organic' pollutants (essentially pathogens, nutrients, floatables, suspended solids and detergents) discharged to the Gulf of Trieste by sewers and rivers are briefly reviewed; about 470,000 people live in the coastal area, and nearly 400,000 of them discharge sewage effluents to the Gulf. This brief review is followed by an evaluation of the impact of such discharges on the quality of marine waters, with reference to the impairment of uses such as bathing and shellfish cultivation. The sanitary and aesthetic aspects of faecal pollution which typically affect coastal waters are examined together with the water quality standards pertaining to bathing waters and shellfish cultivation areas; the extent of pollution of the coastal waters is determined. Experience gained at some wastewater treatment and disposal works is cited. On the whole, the Gulf of Trieste appears to be in a satisfactory condition: more than 85% of the shoreline (totalling 42 km in Yugoslavia and 93 km in Italy) is unpolluted, according to the pertaining standards. Ameliorations are, however, urgently needed in many respects. Recommendations regarding adequate forms of sewage treatment and disposal are made.

Faecal Indicators

In this Research Communication we investigate the microbiological profile of 12 dairy wastewater streams from three contrasting Irish dairy processing factories to determine whether faecal indicators/pathogens were present and in turn, whether disinfection may be required for potential water reuse within the factory. Subsequently, the impact of suspended solids on the inactivation efficiency of Escherichia coli via two means of ultravoilet (UV) disinfection; flow-through pulsed UV (PUV) and continuous low pressure UV (LPUV) disinfection was analysed. Faecal indicators total coliforms and E. coli were detected in 10 out of the 12 samples collected at the dairy processing factories while pathogenic bacteria Listeria monocytogenes was detected in all samples collected at 2 out of the 3 factories. Salmonella spp. was undetected in all samples. The results also indicated that organic dairy wastewater solids had an impact on the performance efficiency of the PUV system and, to a lesser extent, the LPUV system. The findings indicate that the targeting of key pathogens would be required to enable wastewater reuse (and indeed effluent discharges if regulation continues to become more stringent) and that LPUV may offer a more robust disinfection method as it appears to be less susceptible to the presence of suspended solids.

The Impact

To ensure optimum quality at Bathing Waters, the control of diffuse sources of bacterial contamination is receiving increasing attention. As part of an initiative to improve the quality of the EU designated bathing waters on the Fylde Coast (North West England), a project was undertaken to quantify the faecal indicator load from birds and assess the significance on water quality. High bird counts are encountered on the Fylde Coast with gulls, feral pigeons and starlings being prominent. The piers at Blackpool make an attractive roost for starlings with numbers peaking at over 30,000 in late summer. Systematic recording of bird numbers and locations was undertaken during 2001/2. Estimates were also made of the daily faecal organism production by the different species. The spatial distribution of faecal organisms from the bird population was statistically linked to synoptic water quality data. This allowed estimates to be made of the contribution from birds to the faecal pollution load at the bathing waters. The work confirmed a statistically significant link between bird populations and water quality with a marked seasonal bias.
