Biorisk Management and Antibiotic Susceptibility Pattern of Biofilm producing Pseudomonas aeruginosa Isolated from Broiler Chicken: A Public Health Concern
Summary
This paper is not about microplastics; it investigates antibiotic resistance patterns and biofilm formation in Pseudomonas aeruginosa isolated from broiler chicken meat, framing this as a public health concern related to food safety and antimicrobial resistance.
Control of biosecurity and biosecurity within poultry consists of a set of practical measures meant to prevent and control the spread of disease between people and animals. Infections, caused mainly by zoonotic agents, occur frequently due to the lack of safety monitoring regulations, as well as the inappropriate use of antimicrobial products, leading to the emergence of antimicrobial-resistant microorganisms. Pseudomonas aeruginosa, often known as the MDR pathogen has evolved resistance to multiple antibiotics. Because of its propensity to build biofilms in meat and other food products, P. aeruginosa is even more resilient to the phenomenon of drug resistance which is a major public health issue. Standard microbiological and biochemical tests were used to isolate and identify P. aeruginosa from a total of 100 meat samples (20 from each district from broiler chicken meat) gathered from various butcher shops and supermarkets. The Kirby Bauer method was used to identify antibiotic resistance, while the microtiter plate test was used to monitor biofilm formation. It was found that P. aeruginosa was identified from 22% of the broiler chicken meat samples and showed resistance to Cloxacillin, teicoplanin, ciprofloxacin, imipenem, and meropenem, followed by linezolid, streptomycin, amikacin, compound sulphonamide, aztreonam and cefepime which showed intermediate resistance. Multiple Antibiotic Resistance Index (MARI) was calculated as 0.45 for a total of 11 antibiotics. Also, all 22 MDR isolates of P. aeruginosa tested positive for the presence of the biofilm. In conclusion, it was determined that chicken meat was contaminated with Pseudomonas aeruginosa, and these strains that produce biofilms are more resistant to antibiotics. Thus, there is a serious threat to public health from biofilm-forming isolates found in broiler chickens.

This paper is not relevant to microplastics research — it investigates the antibiotic resistance and biofilm-forming ability of Salmonella and E. coli bacteria isolated from poultry feed.
Characteristics of microplastics in typical poultry farms and the association of environment microplastics colonized-microbiota, waterfowl gut microbiota, and antibiotic resistance genes
Researchers investigated microplastic contamination in poultry farm environments and in the intestines of farm-raised waterfowl for the first time. They found microplastics in soil, pond water, and bird guts, with the plastic surfaces hosting microbial communities that carried antibiotic resistance genes. This raises dual concerns: microplastics may both contaminate poultry meat that humans eat and help spread antibiotic-resistant bacteria through farming environments.
Biofilm–microplastic interactions in food safety: mechanisms, risks, and control strategies
This review investigates how microplastics in the food industry serve as surfaces where bacterial biofilms can form, creating complexes that resist cleaning and disinfection. Researchers found that these biofilm-microplastic combinations can shield harmful bacteria and promote the spread of antibiotic-resistance genes. The study evaluates strategies for preventing and controlling this form of contamination in food systems.
Formation of biofilms on microplastics in the food chain and their role as vectors of transfer of foodborne pathogens (literature review, part 2)
This literature review (Part 2 of a series) examines how biofilms formed on micro- and nanoplastic surfaces in the food chain can serve as vectors for pathogenic bacteria, their toxins, and antibiotic resistance genes — potentially increasing foodborne disease risk beyond what bare microplastic particles would cause.
Harmful impacts of microplastic pollution on poultry and biodegradation techniques using microorganisms for consumer health protection: A review
This review examines how microplastic pollution affects poultry health and food safety, finding that microplastics have been detected in chicken meat from supermarkets and open markets. Evidence indicates that microplastics can damage vital organs in poultry, reduce egg production, and accumulate in edible tissues. The authors also review biodegradation techniques using microorganisms as a potential strategy for reducing microplastic contamination in the food supply.
